The IR circuit is the foundation of how the micromouse is meant to see the obstacle, trace the line and detect other robots or preventing from going out of the ring. This is then a key part of the micromouse which a mistake can result in a issue which results in the activation movement going at different time.

The image shown below give us a look at the breadboard key for detecting the IR signals. We can see on the IR circuit that the breadboard only contain one IR LED. This is due to us only needing one as it is very sensitive and can pick up from a wide range. This is why you can see the sleeve on it. This narrows it point of view so it doesn’t pick up unwanted interference. You can also see to LEDs with different colours, this is to allow us to be able to distinguish which side is moving inside the microcontroller. This may seem not needed but when we come to debugging our micromouse this will make it clear what is going wrong.

In addition to building the IR circuit, we must also use the oscilloscope to see the different waveforms of the circuit at different points. Each of these screenshots will represent different points and functions foe the circuit.
