I'm new to this, but I'm stumped on why my IR transmitter circuit won't work. I'm using a TSOP4856 receiver, and a TSAL6100 IR emitter/LED.
Also using a 2n4401 transistor to drive the transmitting part of the setup. The wiring I have looks like this:
The code I'm running uses the Infrared4Arduino library, and the code I'm using is looks like this:
It sends on pin3, using a 56kHz carrier, when I input something to the serial console.
The problem: I can receive data just fine, and the timings get written to serial output. I'm testing this using a remote control I have in my home.
However, when I send a signal using the circuit connected to my Arduino (as pictured) I get nothing. I can visually verify that the LED is firing, because I can see it light up when I view it in dim light with the camera from my mobile phone.
There's something fundamental I'm missing because it seems to attempt to send, but I can't get anything to register and get recorded using both my receiver and transmitter. Any tips would be appreciated.
This is just a test setup to build on - mostly just trying to get something to work at this point. Appreciate folks taking a look.
