#4710 - RE: Increase the IR range |
I am using +5V to Anode of IR LED the cathode is directly connected to an NPN transistor's collector(C458), and emmitter of this transistor is connected directly to ground.
The base of transistor is directly connected to AT89C52 one of IO pin. It is working perfect but with short distance. I would appreciate if any example could be seen. Thanks Rauf |
