Take 4096 LEDs, 64 RGB microcontrollers and four Atari joysticks, throw them (with some degree of accuracy) at a coffee table, and you might get this: a four-way Pong table. The whole top surface of ...

Controlling LEDs is really quite simple. As you know, they need to be current limited which is as easy as applying Ohm’s law to your given set of values. To make things even more even there’s a slew ...

In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

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 ...

The PowerUP Expo is welcoming potential presenters to submit papers for their three-day virtual conference and exhibition, focused on the frontiers of power technology. This year's program includes ...
