hi,
i am doin a project on ucontroller.i have a transmitter & receiver circuit a nd i am cotrolling devices through u controller using these infrared transmitter & receiver. now the prob is of range.when i take transmitter circuit away from receiver(distance=4 inches approx)it does"nt work .help me out
To do a good wireless control, first have to make sure what frequency u are use. Because high frequency and low frequency have different effect on the circuit. When using in high frequency, the miller effecr will affect the amplifier gain.
If you have an oscilloscope you can look at the receiver signal with the transmitter off. This will tell you if there is any interference from the room lights.
