Hi all!
I am making a Arduino E-Scooter! The motor driver requires a PWM signal from 0 - 5V, but I am using an ESP-32, so it only has 0 - 3.3V. I made the circuit attached, and I am wondering if it is ok! Anything I should change? I know this is really simple lol, but I am looking for any tips.
Thanks in advance!
That will work, but it inverts the PWM timing. The "ON" time on input becomes the "OFF" time on output.
Thanks @jremington!
Yeah, I know. Are the resistor values correct?
The resistor values will produce the desired output.
"Correct" depends on other factors, like the load impedance. For a digital input I would use 10K to 100K for the collector resistor.
@jremington ok, thanks!
