Raspberry pi car platform
This project in its current form is a raspberry pi zero based wifi car platform. Although this platform can be expanded into futher projects involving autonomus operation, image recognition this platform currently can be used as a simple keyboard operated car connected over WiFi.
Parts
- Raspberry Pi Zero
- 4 Motor Chasis like this LINK
- Motor Driver LINK
- 2x18650 cells with holder
- Assorted mounting headers
- Wifi dongle (not Req in case of Rpi0 W)
Assembling the chasis. Although i did not end up using these two motor drivers
Almost Done
2 x 18650 cells with battery holder installed
Once you login to your Rpi0 via SSH clone the below code and run it in the terminal
#!/usr/bin/python3
