Bit-banging PWM/Pulse Generator On Any Digital Pin For Arduino
I completed a small software project for the Arduino back in July that will generate a PWM signal on any digital pin. Both the duty cycle and frequency can be specified and there is a full explanation of how the code works in the article I wrote, which is here: https://create.arduino.cc/projecthub/mariogianota/bit-banging-pwm-pulse-generator-on-any-digital-pin-5eb2f9?ref=user&ref_id=1350727&offset=3
There is also a video of the circuit working (see link in the article). It is extremely accurate.
Bill, would this be a good idea for coverage by you in a workshop video? Just wondering.
