Police light emulator with Attiny25

Jan shared his small project where he built a police light simulator using couple blue LEDs and Attiny25 (or other tiny’s from series 25/45/85). Each channel can drive up to 500mA so LEDs can be replaced with LED stripes or bulbs. There are couple effects programmed in that are controlled by using PWM. This project came to mind when repairing toy police car. But this schematic could be used to prank friends or for other purposes. Be sure to check if using it in public wont break the law.

The Fabulous LED Flasher!

If you think that the Light-emitting-diode (LED) is nothing more than an ordinary semiconductor diode that emits light when an electric current is applied in the forward direction of the device, then you must change your thoughts here… Do you know that LED is being classified as one of the most incredible inventions for the electronics components? Furthermore, LEDs are widely being used as indicator lights on electronic devices and increasingly in higher power application, such as flashlights and area lighting. Talking about the flashlights, would you want to build an awesome LED Flasher? Well, this LED flasher is somehow unique than other flasher, as it has five different blink patterns, and it’s the right choice for those that want to decorate their house during the Christmas season… For your information, you’ll need the PIC16F84A and eight high brightness LEDs for this project. Some other electronic components, such as 78L05 regulator, IC socket, Resonator, Switches, Resistors, Capacitors, Wiring terminals, Studs and Printed boards will be needed for this LED flasher project as well! The circuit will control the blink of… Continue reading
