How do I use Raspberry Pi to control DC, Servo motors and some sensors on an Arduino and then use Blynk app to control the motors? I found a youtube video but he didn’t give any instructions.
I found this
and tried to run a DC motor but he used High/Low signal, I’m trying with USB communication so it didn’t work at all.
I need to make an RC car that can be controlled via smartphone and I’m new to this. Thanks for any help.
