Checkout to branch:

git checkout --track origin/<branch_name>

Run the code:

cd PiCar
python main.py

PiCar setup

The Pi is configured to startup in Command Line Interface (CLI) mode and automatically logged in as pi. This saves memory and startup time because the front end GUI doesn't have to load. To manually start the desktop GUI, type startx into CLI.

The password for the default user has been set to picar.

First, I set up hotspot on my phone and connect both the Pi and my laptop to it. Note that the IP address may change when the Pi is connected to different wifi. SSH instructions:

Marty's pi:

pi@raspberrypi:~ $ ssh [email protected]
[email protected]'s password: picar

Tom's Pi:

pi@raspberrypi:~ $ ssh [email protected]
[email protected]'s password: picar
