There are hundreds of homemade thermostats with various MCU and sensors. Some are very simple, others are very sophisticated. However I decided to build my own thermostat especially for a solar panel ...

You can see a video of the tool in operation, below. According to their site, the tool works for timers 1 through 5 on an Arduino Nano, Uno, or Mega2560.

Arduino Uno, or systems based on the ATmega328 chip has no a true analog output. The easiest way is to use one of the PWM outputs and filter the signal with a passive RC filter to obtain an analog ...

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

To create extra channels of 16-bit PWM using the available 4 channels of 8-bit PWM on ATmega328P, this project requires the use of Timer0 and Timer2 in the microcontroller. However, since Arduino uses ...
