So I am interested in building a Controller that will fire relays wirelessly. I would have one handheld controller with 4 buttons Labeled 1-4. The controller will need to fire a relay on 4 field devices. So when button one is pressed module one relay will fire. So when button two is pressed module two relay will fire. (and So On) I am fairly new to these projects and was wondering if anyone could help me find some information on how to do this.
I am almost thinking of soething like a Walkie talkie with multiple channels. Channel 1 fires relay 1 and channel 2 fires relay 2. How can i make a circuit to do this??
Any help is greatly appreaciated.
