TL. DR.
Do the class yourself alone before the class. This is an absolute must. Follow the teacher notes in each section. Do not rush the group. If time is not enough, make more time for these sections.
Connect the car yourself
It is a process that requires some preparation. A few days before each class spend some time to actually move through the content and connect the car yourself. It is very easy to lose the interest of students if you are not prepared yourself. Even if you are a professional engineer, the process of connecting the motors to the controller involves a number of details. Details that are important, that are mentioned in the course, but nevertheless, you should be prepared for them. Move through the content yourself.
It should be fun. Keep the spirit up
In each section, we've provided notes for the students and notes for the teacher on what to do if something is not working. This whole process of finding what is not working, experimenting, working with your hands should be a fun activity for the students. If the challenge that they are facing is too complicated they would give up and the classes would become quite tedious. As a teacher try to motivate and direct them and to keep the spirit up by constantly bringing up the end result of the whole activity - having your own smart car controlled with a phone.

Perfect STEM course. Module 1 - Smart Car with Raspberry PI
Disassemble a remote control car. Change the brain of the car with a smart computer like Raspberry Pi. Build a smart device with artificial intelligence that you could control from your phone and that could freely navigate itself in the real world and on the Internet. Use your hands. Develop programs for your robot and your phone. Be curious and invent.
The perfect course lives up to its name. You move through the content, we check it and return feedback to you.
In the end, you should be able to better understand how to program and design smart devices that would make the world a better place. For everybody age 12+, 16+, 21+, 35+, etc. The hardware costs about 150$. It changes through the years so it might take some time for you to find it as Raspberry PI, motor drivers, power banks and h-bridges.. they change. Note that the course was designed to be led by a teacher with a decent knowledge in embedded hardware and software. This, on the other hand should not stop you, if you are curious.

Connecting overview
We are about to connect the whole car with the lights and motors to the controller. Let's recap to know what is ahead of us, what would the process be and what is the end result of the next couple of sections when at the end we have a car controlled by the phone
