Hardware

Componets needed:

• RC Car (Rock Crawler Reely 1:18) with a controller
  • 
• ESP8266 (WEMOS D1 R2 WiFi)
• 4x Relay 3.3V
• 4x NPN Transistors
• Wires

Hacking Remote Controller with Wemos / Arduino

1. Extract battery and board from the remote controller

   • 

2. Locate buttons on board from RC Controller. There are buttons for each movement: left/right, forward / backward.

   • 

3. Create circuits with relays and transistors in order to simulate clicking on controller's buttons.

   • 

4. Connect wires from each relay to a controller button

   • 

5. Connect wires to Wemos as described in the schema above

6. Done

   •
