Binary Desktop Temperature!

February 24th 2016

A microcontroller-powered binary temperature display for your desk!
A PICAXE microcontoller takes the temperature from a DS18B20 temperature sensor and, with the help of a single shift register, outputs the binary value to a set of colourful LEDs.
It is capable of showing the temperature in either centigrade (default) of fahrenheit (press the botton, bottom, during power-up to enable 'F mode). This kit is capable of showing temperatures from -40'C to +59'C.
Usage Suggestions
it looks great on your desk at home or work. An ideal gift for anyone! Download the source code from the link below and customise it!
