I’m learning. I’m converting an electric scooter I found to a horseless electric roman chariot, for personal transportation, of course, and I’m making the motor controller work today.
I was lead to believe that I could treat my scooter throttle like a big resistor, a big potentiometer. TURNS OUT that mostly they’re hall effect sensors that give you a varying voltage (0-5V in, 1-4 out). I didn’t find a lot of info on this on the internet, but thankfully Geo filled me in on some of the details, and I used my power supply and voltmeter to figure out the rest.
So, my circuit is getting modified (in the direction of simplicity, awesome) and will not involve a 555 to PWM the motors to the tune of a throttle’s varying resistance. I think maybe this is helpful information to publish! More Roman Charioteering to come!
