Smart wireless potentiometer specially design for measure the chemical potentials. Potentiometry is one of the most useful electroanalytical techniques which has a wide range of industrial ...

This project uses two Arduino boards to control the speed of a DC fan using a potentiometer. Three LEDs indicate different speed ranges: red for slow, green for medium, and blue for fast. The serial ...

Call it synchronicity, or manually setting a 16-bit number in an Arduino, or how to turn an OLED into a rotary dial... What am I talking about? Well, I was just compiling the blogs pages for the next ...

A resistor is an electrical device that resists the flow of electrical current. In the digital era, we can find a variety of “digital resistors” for our everyday applications. This article is about ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...
