I’m playing with the Arduino for about a month, and I’ve stucked I’ve got: 2 Arduinos, RF transmitter, RF reciever, button and LED. My project is very simple - when I’m pressing the button, LED connected to another Arduino is turning ON. For about a day I was able to control LED from another room and everything worked fine. Yesterday I backed to my project again, and the distance that I was able to reach had shrinked to 1 meter! Today it suprised me with 1-2 centimeters max range. I’m guessing that tomorrow it won’t work completely. The best thing is, that I’ve tried
- changing RF modules to new pair
- changing power supplies
- soldering an external 17cm antenna
- even changing the Arduinos.
Anybody can tell me what the hell is going on? It is the same code, same room, and exacly same desk as with the first test.
