I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller ...

I made a few initial tests the other day, trying to have the DFR sensor module communicating with my Arduino Uno first using the serial monitor. It works! Note that with the “DFR” sensor, we get a ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...

The build relies on an Arduino Uno as the brains ... [Maker 101] gave the Arduino an infrared sensor which can pick up signals from a simple IR remote control. It can be driven backwards and ...

When it comes to performance, there's a world of difference between the Raspberry Pi and Arduino ... if you're only using one shredder. Aside from the Uno and the ultrasonic sensor, you also ...
