Hey everyone,
since my lighting control is working now i started with the dosing pumps.
Because i‘m an absolute noob the last time i fried my pi zero.
I read about back emf and wondered if there is a protection against it in the circuit from the guide?
Also i‘d like to connect 4 pumps and since i already have the PCA9685 can‘t i use this to generate multiple pwm signals?
Using some transistors to get the right voltage and using the L293D should work, right? If someone could point me into the right direction (e.g. what Transistor to use, how to handle the emf‘s from the motors etc.)
The peristaltic pumps i plan to use are 12V and 250-300mA.
Thanks in advance
