I am happy to present a preview of the first prototype of the circuit that allows me to make "dimmable" my LED light.
The first image shows the components used and assembled:
1 - The ATMEGA168 microcontroller, allows me to manage all other circuits.
2 - The circuit (PWM LED DRIVER) drives the LED lamp. It has a PWM input that allows to set the current of the LED and then the light they emit.
3 - The keyboard used for settings various parameters.
4 - A display showing the details ...
The second image shows the box that contains the power supply, it takes as input the 220V and provides 24V DC outputs.
You can see in the video the fishes, do not get scared anymore. http://www.youtube.com/watch?feature...&v=ES0wxpuqQD4
I set a duty equal to D.060, this means that the leds work to 60% of the maximun power...
Now I'm looking for a suitable container where to put everything...
What do you think?
Ciao ciao Christian
