HI All,
Recently i build a IR communication circuit and still fails to figure out what went wrong..
I hope can get your expert help on this. Below are component list and attach files is my circuit schematics. Please help and this is urgent!!
TX IR Component List
- C1 = C2 = C3 = 120pF, C4 = 10nF (Polarized Capacitor)
- XTAL = 455Khz
- D1 = IN4002 and D2 = IN4148
- Q1 = Q2 = PNP A1015
- LED0 = Infrared Transmitting LED
RX IR Component List
- C1 = 100pf
- R1 = R2 = 39K
- 1738 IR Receiver (38Khz)
- PNP A1015
- Receiver IR Sensor
