As the electrical captain of Aragon Robotics’ Innovation Challenge team, I decided to introduce electrical engineering specifically by designing our own custom PCB to the team. My teammates and I decided to use the board to track stationary bicycle rotations, then translate that to movement in a video game, thus incentivizing exercise. On the board, there’s an I2C that connects to a light sensor, and an on-board HM-19 Bluetooth to connect to the videogame.
After hours redesigning the board, scrupulously placing components, reflowing, and debugging, it finally turns on!
The next steps are to bootload it to run with the sensor.
