I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

We’ve featured loads of IR Arduino projects and they are all exciting and unique. The projects spring from a specific need or problem where a custom infrared remote control is the solution. [Rick’s] ...

To make a remote temperature sensor with the LTC2970, run two different currents (ILOW and IHIGH) through the transistor and measure VBE at both currents (VBE_LOW and VBE_HIGH). The difference between ...

How many times have you wished for a pocket-sized multimeter? How about a mini microcontroller-based testing rig? Have you ever dared to dream of a device that does both? Multiduino turns an Arduino ...

With just an Arduino board, a DHT11 sensor, and an I2C LCD, you can create a simple yet effective weather station at home. This beginner-friendly project displays real-time temperature and humidity ...
