Invent To Learn: Making, Tinkering, and Engineering in the Classroom - Join the maker movement! There’s a technological and creative revolution underway. Amazing new tools, materials and skills turn us all into makers. Using technology to make, repair or customise the things we need brings engineering, design and computer science to the masses. Fortunately for educators, this maker movement overlaps with the natural inclinations of children and the power of learning by doing. The active learner is at the centre of the learning process, amplifying the best traditions of progressive education. This book helps educators bring the exciting opportunities of the maker movement to every classroom. Children are natural tinkerers Their seminal learning experiences come through direct experience with materials. Digital fabrication, such as 3D printing and physical computing, including Arduino, MaKey MaKey and Raspberry Pi, expands a child’s toy and toolboxes with new ways to make things and new things to make. For the first time ever, childhood inventions may be printed, programmed or imbued with interactivity. Recycled materials can be brought back to life. While school traditionally separates art and science, theory and practice, such divisions are artificial. The real world just doesn’t work that way! Architects are artists. Craftsmen deal in aesthetics, tradition and mathematical precision. Video game developers rely on computer science. Engineering and industrial design are inseparable. The finest scientists are often accomplished musicians. The maker community brings children, hobbyists and professionals together in a glorious celebration of personal expression with a modern flare. When 3-D printing, precision cutting, microcomputer control, robotics and computer programming become integral to the art studio, auto shop or physics lab, every student needs access to tools, knowledge and problem solving skills. The maker movement not only blurs the artificial boundaries between subject areas, it erases distinctions between art and science while most importantly obliterating the crippling practice of tracking students in academic pursuits or vocational training. There are now multiple pathways to learning what we have always taught and things to do that were unimaginable just a few years ago. Making for every classroom budget Even if you don’t have access to expensive (but increasingly affordable) hardware, every classroom can become a makerspace where kids and teachers learn together through direct experience with an assortment of high and low-tech materials. The potential range, breadth, power, complexity and beauty of projects has never been greater thanks to the amazing new tools, materials, ingenuity and playfulness you will encounter in this book. In this practical guide, Sylvia Martinez and Gary Stager provide K-12 educators with the how, why, and cool stuff that supports classroom making.

The proximity sensor Bit senses objects in front of it. It can sense if an object is far or near. Try using it to create your own self-navigating car, or a hands-free instrument!

The servo is a controllable motor that can swing back and forth, or be turned to a specific position. Try attaching a flag to the servo to make it wave back and forth! Cross Axle: This servo has a cross axle shaft that works with any littleBits accessory with a cross axle opening. Hub Mount: Note that this bit is NOT compatible with the following kits. - Space Rover Inventor Kit - Cross axle mechanical arm (not available separately) - Cross axle motorMate (not available separately)

The RGB LED (or "Red-Green-Blue Light-Emitting Diode") Bit is a special light whose colour you can adjust. Use the included screwdriver to adjust each of the colour channels to get almost any colour. Use the RGB LED when you want to match the light to the colour of your creation!

The number module displays information about the signal it’s receiving from your other modules. It features a two-digit, seven-segment LED display. In the “read” mode, the module displays information about the signal it’s receiving. In the “count” mode, the module counts up or down with each trigger. The counter can be reset by receiving a trigger at the reset bitSnap. Geek Speak This updated number module has 2 main modes and 2 settings under each mode. Use the 4-position switch to choose between the modes. READ MODE: Read mode has two settings: values and volts. The number module reads the voltage on the input bitsnap, then calculates and displays either a value between 00-99 or a voltage between 0.0 - 5.0. The voltage on the output bitsnap is a filtered PWM value that equals the voltage on the input bitsnap. COUNT MODE: Count mode has two settings: up (from 00-99) and down (from 99-00). A step to the next number happens on input low-to-high transitions. The voltage on the output bitsnap is a filtered PWM value that is proportional to the number on display. For example, if the displayed number is 50 then the output voltage is 50% of 5V, or 2.5V. The RESET bitsnap can be used in this mode to reset the number on display. In the "up" setting, the display resets to "00". In the "down" setting, the display resets to "99". The RESET bitsnap resets the number on low-to-high transitions. Under the Hood An Atmega168 is used to constantly read the signal from the switch and determine which mode the module is in. It also reads the buffered signal from the input bitsnap, and sends a PWM signal through a Sallen key filter to the output bitsnap. In "read" mode, the signal from the input bitsnap is passed from the ADC pin to the PWM output. In "count" mode, a step to a new number is triggered on a low-to-high pin-change interrupt on the ADC pin. A PWM lookup table is used to output the corresponding PWM value. The reset is also triggered on a low-to-high transition. The Atmega168 also controls the seven-segment LED display to display the correct value.

The littleBits LED (or "Light-Emitting Diode") Bit is a very small board that shines a nice green light. It's our go-to when you want to light something up.

The DC (or "direct current") motor rotates a small shaft you can attach anything to. Try attaching a wheel! Use it to spin, turn, twist, and roll.

The buzzer Bit is just what it sounds like: it makes a noise that you just can't ignore. It buzzes whenever it gets an ON signal. Try using it to make your own doorbell or alarm!

The bargraph is one of littleBits favourite Bits: The bargraph shows you how much signal the Bit is receiving with a display of 5 light-emitting diodes (LEDs) in different colours. Try it with a pressure sensor to make your own strength-o-meter.

The toggle switch Bit is sturdy on/off switch that you can use to activate your creations with a nice, solid click. Try using it after a USB power Bit as an on/off switch for your whole creation.

Think of the littleBits threshold as a toll booth for signal passing through your circuit. The threshold compares the incoming voltage coming from the bit snapped before it against the voltage amount you’ve set by the threshold knob. If the incoming voltage value is greater than the selected voltage, the threshold will allow the signal to pass and activate any bits (lights, motors, etc…) following it. If not, then nothing will be activated. Use it to make any sensor module into a trigger module! The threshold is a minimum parts count design, using only a single opamp to accomplish the task of comparing the input signal to an onboard reference that is set via the potentiometer control. U1 is configured as a non-inverting comparator with approximately 100mV of hysteresis provided by R1 and R3. VR1 provides the comparator's reference. C1 is a bypass capacitor for U1 that sources current to the opamp during fast switching events.

The littleBits temperature sensor responds to the temperature surrounding its probe. The higher the temperature it senses, the more signal it sends out. The temperature sensor determines temperature via the IC that is located on top of the board. It communicates via I2C with an MCU located on the bottom of the board. The MCU gets a temperature reading in Celcius, applies a hysteresis to the reading, then converts it to farenheit if necessary. The final determined temperature is converted to a number module readable analog value. Every 50mV on the output of the bitsnap represents a single degree in either Farenheit or Celcius. Since heat will conduct through the board itself, there are slots around around the temperature sensor which provide thermal relief from board conductivity. Not Waterproof: littleBits are not waterproof. Please do not put the temperature sensor in your mouth to take your temperature. Plus, they taste weird so you will wish you hadn’t.

It functions just like a light dimmer you might find at home, or a volume fader in a recording studio. Follow it with an LED for some adjustable mood lighting.

The remote trigger lets you use a common remote control with your modules. Make your littleBits circuit and point your remote control at the remote trigger’s sensor. Then, press any button on your remote control to activate the module. The remote trigger will work with almost any button on a remote that uses infrared light to send signals.

The pulse Bit is like an electronic heartbeat. It sends out a stream of short ON signals, and you can make the speed of the pulses faster or slower using the included screwdriver. It's great for making LEDs blink!

The pressure sensor is a touch-activated module; give its pad a little squeeze to activate it. The more pressure you apply, the more signal it sends out. Put it in front of a vibration motor to control how much it shakes!

The motion trigger is similar to the sensor on an automatic door: when someone is moving nearby, it sends an ON signal to the following Bits. It's very sensitive, so don't breathe unless you want to be detected! Try it with some LEDs to create a security light!

The littleBits light sensor measures how much light is shining on it. It has two modes: “light” and “dark”. In “light” mode, the more light shines on the sensor, the higher the signal it sends out. In “dark” mode, it's just the opposite – the signal increases the darker it gets. You can use a screwdriver to adjust the sensitivity. Use a bargraph to see how it's working!

The littleBits envelope modifies the loudness contour of a sound. It takes a sound input and shapes it into something you'd hear from an acoustic musical instrument, like a piano or saxophone. This envelope has two controls: "attack", which is how long it takes to ramp up to maximum volume, and "decay", which is how long it takes to go down to silence again. You can use its third bitSnap[TM] to trigger the envelope from different sources, like the keyboard. [Try it putting the envelope after an oscillator being controlled by a micro sequencer.]

The button Bit is a classic: big, round and springy for comfortable pressing! Push to turn your creation on, and release to turn it off. Snap a buzzer in place after your button to sound out signals in morse code! The button module will make or break the signal path between two modules. When the button is pressed, the output of the module is directly connected to the signal line input. When not pressed the output of the module is weakly pulled low through a 1meg resistor.

The wire Bit is just what it sounds like - it allows you to physically separate your Bits. Try it whenever you need to break up your chain of Bits, like when you need to put a light at the top of a model building! You'll find many situations where you want a wire Bit.

The littleBits split module sends a single input to two wired outputs. It's great for connecting one output to two inputs, like using a keyboard to control two oscillators. But keep in mind that it can be used just like a wire module if you ignore one of its outputs.

Use the littleBits latch to turn any momentary input, like a button or a trigger module, into an ON/OFF switch, like a toggle! If you place a button in front of the latch, pressing the button once will turn it ON, and pressing it again will turn it OFF again. Or for even more fun, place a sound trigger in front of the latch, and a light after it...then, just snap your fingers!

The littleBits inverter is a very contrary logic Bit. It sends out the opposite of whatever it receives: send it an ON signal, and the inverter changes it to an OFF signal, or vice versa. Try putting it between two lights after a button: clicking will make the LEDs blink back and forth, like the lights on top of a police car! The lights on top of a police car flash back and forth. A pulse sends a signal to both of the lights, but they flash opposite one another due to the inverter.
