A cable connecting the controller with the motor driver could be broken. This happens when closing the car. Because of the force applied, if there is not enough space for the driver, the cable might be broken
The is the whole step-by-step process of connecting the motors with the Raspberry PI with the driver and the batteries. No scheme needed. Everything is already here. In the course, the motors are part of the car and the batteries are in the batteries holder, but with this scheme, you could see the whole process.
In some cases, the two lights will not work. The voltage will not be enough if you connect two diodes one after the other, no matter if it is with or without a resistor.
Here we will start sending manual commands to our Raspberry Pi micro-computer and it will execute them for us.
Now it is time to import a complex program and to learn from it.
Here we have detailed explaination what we expect from you. Bonus: how to do copy-paste within nano.
We want to be able to interact with the car and its programs and we are going to add the simplest sensor, a button.
You already know the process. Open nano, copy and paste the material code with a right mouse click, save the file and execute the program.
These challenges will throw you in the deep water, get prepared and read carefully.
