Hardware Design The hardware section, where I'll
show you how I built the transmitter and receiver is split into two sections,
one for the transmitter and one for the receiver. Below are detailed
descriptions and pictures of my step by step construction of the transmitter.
Building The Circuit
I always like to begin assembling a circuit by having all the parts for it
laid out in front of me. When working with a breadboard a pair of needle-nose
pliers can also be helpful for getting wires into the breadboard holes.
The first step is getting the power regulation
circuit on the breadboard.
Afterward we add the PIC circuitry, with a
crystal and 10kΩ resistor.
Now, I added the first 2n2222 buffer stage for
the IR output.
The final step is adding the 2nd part of the
2n2222 buffer stage, and IR Emitter.
Hopefully that was seemingly painless, the circuit is not too complex and
therefore fits nicely on a breadboard. Now let's make the receiver!
