Audio oscillator with frequency counter

Friday, April 17th, 2015

Xristost blogged about his DIY Audio oscillator with frequency counter project: After I finished the oscillator, I made some minor changes in the square signal part of the schematic. I connected five of the inverters in parallel with low value load resistors, thus reducing the influence of the parasitic capacitance of...

Optically controlled servo motor

Thursday, October 23rd, 2014

Dilshan Jayakody  writes: This is demonstration project to control servo motor movement using physical marker and normal video camera. In this project video camera capture the movements of marker and calculate rotation angle based on that. This calculated rotation angle is feed to the servo through small MCU based interfacing...

0-99 minute timer

Thursday, December 1st, 2011

Raj decided to make a tutorial on how to implement a 0-99 minute timer on a PIC16F628A microcontroller. His design uses a HD44780 compatible 2x16 text LCD, to setup and display the count-down timer. One pin of the PIC should be used to drive a relay, but for testing purposes...
