Bluetooth Mini Pickup Truck

I've built a bluetooth pickup truck to transport your daily goods!

1. ESP-32
2. Jumper cables or wires
3. 8x AA Batteries
4. Battery Pack
5. 2x Battery Terminals
6. 2x LEDs
7. 2x Hobby Gearmotors
8. 2x Hobby Gearmotors Wheels
9. 2x H-bridge Motor Drivers
10. Ultrasonic sensor (4-Pin)
11. Soldering Iron

Start by attaching your ESP-32 and motor drivers. Then add your wires. Follow this diagram for an easier understanding. Using the TinkerCAD link, finish up the wiring and continue with attaching the wheels to your motors.

Next solder the LEDs and the Ultrasonic sensor with spare wires. Attach them to their respective locations on the ESP-32.

With the following code file, send it to your ESP-32. While you're waiting for that to upload, download the LightBlue app on iOS or the Bluetooth Serial Terminal on Android. If the code was sent successfully, you should see "ESP32-Robot-BLE". Click connect and now enter the application. You should see a section where you can write and then make sure you're format of information is UTF-8. Now write letter "F" for forward, "B" for back, "L" for left, "R" for right and "S" for stop. This is your method of controlling!

Now print out the following file and slide all of your different components into the car. Enjoy!
