Danny Staple builds robots and gadgets as a hobbyist, makes videos about his work with robots, and attends community events such as PiWars and Arduino Day. He has been a professional Python programmer, later moving into DevOps, since 2009, and a software engineer since 2000. He has worked with embedded systems, including embedded Linux systems, throughout the majority of his career. He has been a mentor at a local CoderDojo, where he taught how to code with Python. He has run Lego Robotics clubs with Mindstorms. He has also developed Bounce!, a visual programming language targeted at teaching code using the NodeMCU IoT platform. The robots he has built with his children include TankBot, SkittleBot (now the Pi Wars robot), ArmBot, and SpiderBot.

Writing code to test your motors

Before we get stuck in and do fancy things with the motors, we need to get them set up and test them. This way, we can make sure they work and iron out any problems.

We need to download the library to work with the motor board we have chosen. Many robot parts, apart from the simplest ones, have an interface library to control the motors and other devices on the board. It's time to log in to your Pi using PuTTY again.

Preparing libraries

We download this code from a project on GitHub using Git on the Raspberry Pi. So, we need to install Git on the Pi; we also need I2C (i2c-tools and python3-smbus) and pip to install things into Python. Type the following command:

pi@myrobot:~ $ sudo apt-get install -y git python3-pip python3-smbus i2c-tools

To get the library for the motor board, Raspi_MotorHAT, we use Git and download it from GitHub, installing it for use in any of your scripts with the following command:

pi@myrobot:~ $ pip3 install...
