LEGO Arcade Joystick

Below is a project I did at home. I built a Bluetooth arcade controller out of LEGO bricks. It incorporates an ESP32 (Arduino) micro controller that is used to to send Bluetooth gamepad button data to Bluetooth compatible devices. The electronics are mounted as if they are LEGO bricks. This idea has the purpose of not only making a fun open source project, but also to create a faster way of building electronic prototypes with the use of development boards.
