I update the code. It can use for any no of relay from 1-8. In this hardware I only use 4 relay.
Also I add 2 new command for 'ALL ON' and 'ALL OFF'

Hi. I'm a student and I'm doing a project which requires me to connect my microcontroller(8051) to some 240VAC home appliances using relay. I don't know which relay should I use but my project is a bit similar to yours, so I think I can use the same type of relay. So can you tell me what model of cytron relay circuit you used in the circuit? that will help me a lot. Thanks.

Relay no model. Just go to electronic shop and pick relay with the current rating you want.

hie can i have code for gsm module that send msg once detected obstacle
component that i used is arduino uno+ gsm 900A..please send me asap...urgent need
