At the beginning of this video tutorial, we would have two separate cables. At the end of the tutorial, we would have a single, longer cable. The two cables will be connected to each other using a Heat-Shrink Tubing
This part of the course is challenging for many of the students.
Remember how we have the diode blink when connecting with the Phone to the Raspberry Pi. Now we would like to make the car lights blink when connecting with the Phone to the Raspberry Pi.
We would start connecting a lot of things to the Raspberry Pi. It will be good if we could have some way of referring to the pins on the Raspberry Pi. For example like Pin 5 or Pin 26. Luckily there is such a way.
Every electronics tutorial, book or course about Raspberry Pi or Arduino will use a motor driver. Very few of the courses will actually explain why do you need a Motor Driver, what is it for?
For powering the motors we would use the batteries that are in the remote control car. Not the power bank, but the batteries. We should connect the batteries to the Motor Driver
The power in the car comes from the batteries. The batteries are in a batteries holder. About 5 of them. Two cables are connected to the batteries holder. It is very important to identify which of those cables is the plus and which is the minus.
It might be tempting to move to all the other cables very fast and finish connecting them very quickly, but it takes time and it is important to be careful. Debugging the cable connections after they are connected is an interesting, but tedious task.
It's time we introduce you to all the elements on the L298N Motor Driver. What are the names of the different elements and how are we going to refer to them.
