Technical requirements
Before we get started, make sure you have the following parts:
- The Raspberry Pi robot and the code from the previous chapter: https://github.com/PacktPublishing/Learn-Robotics-Programming-Second-Edition/tree/master/chapter10.
- Two slotted speed sensor encoders. Search for slotted speed sensor, Arduino speed sensor, LM393 speed sensor, or the Photo Interrupter sensor module. Include the term 3.3 V to ensure its compatible. See the The encoders we are using section for images of these.
- Long male-to-female jumper cables.
- A ruler to measure the wheels' size on your robot – or better yet, calipers, if you can use them.
The code for this chapter is available on GitHub: https://github.com/PacktPublishing/Learn-Robotics-Programming-Second-Edition/tree/master/chapter11.
