Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

The project uses a PIC16F684 microcontroller to control this LED chaser face wherein various patterns are followed by the LEDs. Different patterns can be made and added with the help of the SMD ...

Interested in teaching circuits to kids on a budget? You can build circuits and program Arduino microcontrollers in TinkerCAD, and we’ll show you how. This free two-hour workshop will teach you some ...

The project illustrates how LEDs provide current flow from light when put in backward position. The output of the photodiode needs to be amplified for the light-detection signal to be useful in most ...
