Description
This project uses minimal materials and was made from mainly spare materials which I have access to. It was inspired by Microsoft's Otto robot which inspired me to create my own micro-version over the past few days.
Parts List:
-ESP32 C3
-MX1508 Motor driver
-MT3608 DC -DC converter
-FR107 Diode
-1000 μF Capacitor
-LED
-20mA Resistor
-Battery Connector (Male and Female)
-2x 612 DC Brushed Motors (3v)
-12mm Shrink Tubing
-Enameled Wire
-2x 550mAh Lithium Batteries (I took mine out of recycled vapes)
-Multipurpose lithium Ion Battery Charger (Or TP4056)
The wire diagram is slightly complicated but I will included it, alone with the most recent code that I created. The car can be controlled on the phone, or computer. Simply connect the battery, connect to the broadcasted wifi network, search "192.168.4.1" on the browser, and the controls will display. Refer to the images included. Please like, comment, and share!
