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 ...

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 ...

The main focus of this project is to create extra channels of 16-bit PWM in the MCU using the available 4 channels of 8-bit PWM on ATmega328P. This is important because high-resolution PWM is ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using the ...

I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough to build into a prototype. See also: An AVR ...

A new fully featured Arduino development board has been created called the Prestissimo Uno+ which is now available to back via Kickstarter with earlybird pledges available from just $20, AUS$28 or ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...
