Arduino DC Motor Control with a MOSFET and tachometer

[@ronshaw80]

You videos on the Arduino has prompted me to order one from Amazon. I am an analog type, so digital is foreign to me, but I will start learning what I can. Great videos.

Hello, nice video :-) The motorola is not starting very slowly. For get a slower speed start, you can decrease the PWM frequency. The Arduino standard PWM frequency is about 500Hz depending on the pin you chose. For a motor, a PWM frequency of about 100Hz is far better. ( a few more or a few less depending on the motor) A great key of using PWM is firs, try to use frequency lower as possible for the system. If you try with lower frequency, you will probably can start the motor very slowly.

this is what got me into electronics. I wanted to convert a car to electric. then saw the price of the motor controllers for series wound brushed DC motors. I would still like to build one. I have forklift motors. two of them are almost new. I have three all together. seeing this I was wanting to ask. could a arduino be used to base a controller off of? use it for the pwm. and for over temp of the MOSFETs. and over volt and current protection. with a little modification the motors can handle about 72volts +. I would want a temp warning or a gauge on the motor or motors. with about 600-800 amps current capacity I think it should survive. giving the voltage capacity of the FETs. it would be nice to harness the back emf from the motors some how. I have seen videos of ppl experimenting with doing so. I don't want to take the motors apart to do so. I would like to start with a smaller motor controller and work my way up. I do have smaller motors. I guess a e bike would be a good start. thanks so much for the knowledge you share.

+James stranger Yes you could use an Arduino for the motor logic. Definitely going to want some heavy duty to to talk to the motors though.

My remote control car witch I lost the remote for,has a circuit board with a 3vdc Relay. Since I lost the remote to the car I scrapped the circuit board an added a Arduino an motor shield. What I wanna know is will I have any problems using a arduino uno. Also the car uses a 7.2v battery the motor is slightly larger than most remote controlled cars, so I wanna know is will there be any problem with the method I’m going to use with the arduino uno & the motor shield

[@learnelectronics]

+Steve Jenkins No, you shouldn't have any trouble.

Thank u so much for the feed back 👌👌😁👌👌👌👌👌couldn’t thank u enough

Hi! Brilliant videos! Thanks! You mention in the video that there is a 4th video coming up containing PID for maintaining the speed regardless of load on the wheel. Where can I find that one? Br. Pelle

Haven't done it yet.

A question,when in the map statement the 0,1023, 0, 255 should the last part be 0, 254 or does it make any difference? Thanks for putting the pieces together for us!

[@learnelectronics]

+George Chambers 255 = always on

[@georgechambers3197]

Ah thanks, I wasn't sure.

[@learnelectronics]

+George Chambers No problem George. Think of it like this...0 is off, 1 is the lowest PWM value, 254 is the highest PWM value and 255 is On. 0 and 255 are like doing a digitalWrite()

[@georgechambers3197]

OK, I wasn't thinking of the PWM I was thinking like a programmer? Guess I need to pay attention to those things too! Thanks Paul.

Please make a playlist of you vids, or oganize them cause if been looking for part 4 but Cant find it.

@@learnelectronics thx so much, my yt was doing weird things but by going to thé link it worked, din't Found part 4, but but continued making thé timer😁 thx again.
