The Idea
Read moreMany older cars use simple dim light bulps. Most modern cars have leds with nice on/off transitions. What if we could bring nice bright LED lights to the older cars.
PrototypeFor the prototype I first looked at how my interior light is wired. After some dissassembly and measuring with the multimeter, I got this simple scheme to how my interior light is wired.
- Door is only connected to ground when a door is open.
I also labeled the inputs and output inside my interior light.
I recreated the switch part on a breadboard with a switch and button:
The push button acts as the door sensor.
Finally I added some leds, a mosfet, potentiometer and microcontroller to control the leds.
A demonstration of the prototype.
