Title Short description
Connecting two LEDs on a single uC pin v2 How to connect two LEDs on a single microcontroller pin.
Dual LED 12V blinker Double LED blinker on 12V.
LED VU-meter LED VU-meter using opAmps.
LED display with Atmel microcontroller LED display with AT90S8535 controlled with PC keyboard.
LED signal level display Device uses MAX924 IC.
Remote RGB LED strip driver with PICBasic If you have some RGB LED strip leftover from your previous project, do not let it go to waste. Why not building a simple three channel PWM driver with IR remote control support to power it with? It is a great weekend project that anyone can build. This project is based on an old PIC16F84 we had lying around, three 1A transistors and an IR remote receiver. The firmware is written in PICBasic and is commented out so beginners could learn a thing or two about the way that device works. There are few firmwares available that decode: Nokia remote protocol, Sony and Philips.
VU-meter with 6 LED diodes VU meter with 6 LED diodes with no power supply.
Word Clock A clock that tells time with words. Parts used: ATmega168P/328P, DS3231/DS3232 RTC, AT42QT1011 capacitive touch sensor and MAX7219 dot matrix driver.
