It is a simple construction of 8-channel lights controller.
The controller uses 5V converter on LM2574 and 2A polymer fuse. Maximum load of no more than 40W per channel.
Atmega16 works in the system to provide enough space in the FLASH memory for special light effects.
The program may consist of many elements switched every 20-30 seconds.
Additional pin /SS was brought to the programming socket, so a full SPI is reached.
Also a radio module can be applies in order to use a remote control or computer to control the driver.
Simple desk lamps with clamps for attaching can be used as reflectors. Each of them can be connected to the controller by a special extension.
Note! Mains voltage is used in the system.
