Give +12V power supply to AVR Slicker Board; the Relay module is connected with AVR Slicker Board. When the program is downloading into AVR in Slicker Board, the Relay module is ready to work. Connect the serial port cable from pc comm., Port to AVR Slicker board. The relay will be ON if the controller receive the character ‘C’ and OFF if it receives ‘D’.
If you are not getting any output from Relay, then you just check the configuration switch settings & check the Relay is connected properly. Otherwise you just check it with debugging mode in CodeVisionAVR.
