Building an Arduino speed detector using IR technology to measure the speed of a moving object is much more cost-effective, ...
This isn’t about connecting a temperature sensor in your Arduino. This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno ...
[mircemk] shows how to create a simple non-contact proximity sensor using little more than an Arduino Nano board, and a convenient software library intended to measure the value of capacitors.
