i was wondering if somebody could help me with a project im working on. i want to make a radio controlled switch. I want to build both the receiver and transmitter myself i was looking into RF modules and relays but ive never used any of these components before so i would appreciate any help with that also any hep with the actual project IE ideas,new directions, schematics. I'm hopeing it will have about a 2-3 km range and im not adverse to using pic's but as much detail as you can give on it would be really beneficial as ive never used them before. thanks in advance for all your comments and help. ps I've posted a few links below of a few sites I've found helpful
