This is one of the most important steps in building our Micromouse getting the PCB in place. This tiny circuit board is what brings the whole robot to life, connecting all the sensors and making sure they can talk to the microcontrollers. It’s what allows the Micromouse to sense where it is, process that information, and send the right signals to move in the right direction. Without it, the robot wouldn’t be able to navigate or avoid obstacles. Now that the PCB is set up, the real fun begins testing, troubleshooting, and fine-tuning everything to make sure it runs smoothly.
