This little guy staves off (or welcomes) the sun by monitoring the room with a temperature sensor ... Arduino shield from some perfboard to which he added a handful of discrete components: some ...

I recently had to build an infrared close proximity sensor ... Arduino Uno (TP2). See a couple of random oscillograms below. Thus, the infrared emitter transmits bursts of 38kHz infrared signal ...

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 ...

Arduino, the building block of many off-hours ... A knob, eight LEDs, a proximity sensor, a motion sensor, a simple buzzer/speaker, a temperature/humidity sensor, and three simple buttons.
