Shift Register + Potentiometer
Posted: Fri Nov 23, 2018 2:44 am
I am using Arduino UNO as my microcontroller and my goal is simply to control 7 individual LEDs and their brightness altogether. I intend to keep using Arduino UNO and not upgrade to Arduino MEGA or something. Arduino UNO only has 6 PWM pins, so I am short one PWM pin, that is why I am trying to use the shift register.
It seems to me that it can help me to control the LEDs, but I do not see how I can control the brightness combined with the shift register.
Is it just not possible? or
Any suggestions for other methods or components to try?
Thank you.
