| + | The ESP 32 Dev Module is plugged into a breadboard, with the ground pin connected to the power rail, as well as the 5V pin. There are two IR FC-51 Sensors on a smaller breadboard, with the ground pins connected to the ground rail, the VCC pins connected to the 5V rail, and the output of the "left" sensor to the 34th GPIO pin, "right" being pin 35. In addition, two buttons, connected on another breadboard for "forward" and "back". They get ground from the main ground rail, and their other connectors are plugged into pins 27 and 26. | ||
