How to connect third-party motors to Arduino?

Question

Arduino

There was a radio-controlled car at home. I wanted new sensations, and I decided to put Arduino instead of the machine board and control it via Bluetooth. The program for connecting to the phone is written, the engines are connected, launched, but nothing works. Began to dig. Moved the program for the engines into a separate sketch. Launched - does not work. There are no errors while compiling. Can you please tell me how to access the port in order to start the engine?

Answer 1

How did you hook up the engine?
Considering that there is not a word about the drivers, I will immediately say that the engine will not spin directly from the controller legs. :)
You need to fence the driver to control the engine / buy a ready-made shield.

Answer 2

google "l298n connection"
