Hello, I love your videos. One question. By any chance have you made a video the allows you to use a push button to turn the dc motor on and off? This would allow you to turn it on and off. I'm trying from your code but I'm having issues for some reason. If not, thank you anyways. Again, great videos.
could we not power both VCCs from the power supply, provided that it outputs 5V? Also, would connecting all ground leads (4 from the L293D, 1 from Arduino and 1 from power supply) together on the ground bus of a breadboard work? Or do they need to be separate? thanks for the video, very helpful
