This add-on pack gives an existing Nezha Inventor's Kit or TPBot car a new set of senses. A colour recognition sensor and a gesture sensor let students build projects that respond to what they can see and to a wave of the hand — the point at which coding starts to feel like artificial intelligence rather than switches and timers. What's included: Planet X colour recognition sensor Planet X gesture recognition sensor Planet X NeoPixel light ring Planet X trimpot module Four RJ11 (4P4C) connecting leads Over 180 building bricks micro:bit, TPBot car and Nezha board are not included — this pack expands a kit you already own What students practise: Working with sensors that classify rather than simply measure Mapping an input range to an output using the trimpot Extending a project they have already built, instead of starting over Block coding in MakeCode with the Planet X extension Six documented projects on the ElecFreaks wiki introduce the ideas behind machine perception in terms a primary or lower secondary class can follow.

The TPBot works straight out of the box without a micro:bit — it will follow a line and avoid obstacles on its preset modes alone. That matters in a classroom, because a child who is stuck can still see the thing work, then slot in a micro:bit and start changing what it does. What's included: TPBot smart car with an ABS shell Line-tracking map Sticker sheet and user manual Runs on 4 x 1.5V dry cell batteries, not included micro:bit board is not included — add a micro:bit V2 at checkout What students practise: Sequencing and steering — getting a robot to follow a planned route Using sensor input to make a decision instead of running a fixed program Block coding in Microsoft MakeCode, with Python available for older students Designing a body for the robot, then testing whether it still drives properly Lock joints on both sides and studs on the roof take standard building bricks, so the same car becomes a police car, a delivery truck or a football player. Four sensor connections and four servo connections allow expansion, and it works with our Interactive Coding Accessories Pack. Winner of a bronze IDEA Design Award. Measures 113 x 128 x 90 mm.
