Hello, in this project I want to show you how to build a multi functional Police Light with a Attiny25/45/85 .



It will have serval animations , which can be changed with a button on the circuit board, it has 2 channels, which can be controlled with PWM. That allows us to add serval animations or police light flashing sequences. The maximum rated current per channel is 500mA, that allowes us to control high power LED´s, LED stripes or old Light Bulbs!



Why did i build this?



Well, my motivation was a colleague of mine is a huge fan of very old toy cars, so he asked me if i can repair a broken police light of one of this cars. As it was a american car so a astable multivibrator wasnt a possibility. That is why i used a Attiny to controll it, that allows us to add serval animations!

Voltage: 5V

Current(stand by): less then 10mA

Serval animations

2 Channels

Both output channels have PWM

Output Current per channel: 500mA

On/Off button

Animation change button

Small size
