PCB Terminals
Looking at the picture we have a total of 7 blue screwdriver connectors. These connectors are called PCB Terminals. That is the official name. You can search on the internet for it and you will see many other such terminals.
The two on the left are for motor A. In our case these will be used for the back motor that will drive the car forward and backwards. On the right, we have two other blue connectors that will be used for turning left and turning right.
Input Pins
There are four pins on this driver numbered 1 to 4. These are called input pins and they should be connected to the controller.
Jumpers
We know. We know. It is getting quite tedious with the new names. Only three more. We promise.
In the picture below, you could see 2 of the 3 jumpers that the motor driver has. They are highlighted. The jumpers simple connect the output PCB Terminals to the Input Pins.
Capacitors
We are not going it use them in any way during this course. The capacitors are the two large cylindrical elements.
Radiator
Where there is current there is also heat. The goal of the radiator is to disperse this heat.
The driver from Below
Take a look at the driver from below. In the picture, you could see the out 1,2,3,4 highlighted.

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.
