In this tutorial, we will develop a 5V variable voltage source from Arduino Uno. For that, we are going to use ADC (Analog to Digital Conversion) and PWM (Pulse Width Modulation) features. This ...

If you ever wanted to adjust a circuit using a digital version of a potentiometer (variable resistor) controlled by an Arduino then this is the easy way to do it - and at a price that won't break the ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...
