This is an android dimmer which also works by hand,
The power on the servo's is only there when it's android operated with a HC-05.
it works with an Pro mini atmega168 or 328
The program drives a servo which drives 3Dprinted gears on a simple triac dimmer,
so you can control any lightbulp by hand or phone or tablet.
Step 1: Build Dimmer
First i did build a simple bulpdimmer on a cheap pcb, you alwayskeep in mind
the voltage can be dangerous , all parts including the potentiometer have high voltage !!
Step 2: Circuit Building
First order your stuf from the picture above, i got mine from ebay, but you can buy them anywhere.
don't forgot to order the buck converter and the 9 gram servo(s)
I did build it on a pcb as you can see,
Before connecting the power to the board, be sure the adjusted power does'nt exceed 5 volt !!
This cicuit does'nt only dim a bulb, it also controls a fan, wich i use for my Bbq.
If you don'nt need this you just leave the parts away.
Step 3: Programming
You have to program the Pro mini atmega 128 and here is the program.
Here are the files to print the gears on a 3D printer.
