Recognizes the distance of an object away from the sensor up to about 10 inches (~25cm) and the location of the object from side to side across the sensor in about a 6 inch (~15cm) span. You will be able to use I2C or UART to communicate with the ZX Sensor via an Arduino-based microcontroller as well as a computer. SEN-12780

An educational kit for learning electronics and programming using the BBC micro:bit. It allows you to create creative projects combining crafts with interactive elements like a motor, servo, or touch-controlled light. The kit is powered by three AA batteries, has an on/off switch, and is operated via the MakeCode editor with a dedicated extension. The kit includes an instruction booklet and two ready-made projects to get you started quickly. Kitronik 56132
