Hi guys,
I have a small DC motor which I want to control the speed of using a 10K pot as an input.
I would normally go about this by using a 555 timer circuit, but we are in lockdown at the moment and I don’t have any on hand. My idea is to use the 14m2 that I have and PWM control to control the speed based on the value of my pot.
However this is where I need help as I wasn’t able to find any circuits with that setup.
The components I have available right now are... a 10k pot, various resistors, Picaxe 14m2, ULN2003A motor driver, Various NPN and PNP transistors, a few power diodes, an irfz44 mosfet and of course the small DC motor I am using.
I am planning to power the motor and Picaxe chip from a 3.7V Lipo battery.
If someone could suggest how I could make this work with a schematic and code that would be fantastic and much appreciated as I am a novice with Picaxe still.
Cheers
