8V and 22V

This thin silvery ribbon is an interesting sensor

We thought this could really make for a great breakout

Micro:Bit offers a much more graphical way of working and programming with microcontrollers

This is the Standard RCA version which uses RCA connectors that you know from your normal stereo equipment

Pololu QTRX-HD-07A Reflectance Sensor Array: 7-Channel; 4mm Pitch; Analog [Discontinued] _RPI_CASE_AUDIO 8V and 22VThis Pololu IR LED phototransistor pair is great for precisely identifying changes in reflectance (like line detection). It operates from 2. 9 V to 5. 5 V and offers dimmable brightness control independent of the supply voltage. In general, the closer the object, the higher the contrast between light and dark readings, but high reflectance objects are generally detectable out to around 40 mm. This version features a high performance, low current QTRX
