LEGO/Arduino Magnetic Stirrer

I accidentally turned the power supply/motor driver off and the fan kept going. Where is it pulling power from then? From the digital pins?

Rose. I want you to know that I have been following your lessons and, as a 70 year old Retired Electronics Technician, these lessons are a fantastic refresher for me and look forward to watching all of your lessons.

Aaarrrggghh it's not working 😢.
Maybe my chip is broken.

Hello sir, I am Milad Mirzaee, a student of MSc mechanical engineering at University of South Wales in UK. I have to thank you for such great videos, and I highly appreciate your explanation of the physics behind the hardware you used in these lessons. I really enjoy knowing the mechanism they work, otherwise, we can get the code from anywhere. I have to mention that I have watched all the 37 videos in full so far and I will continue doing so for the rest of the videos. As I remember the last few videos, the codes were Indigo, Rose and the name of your grand daughter who is going to visit you soon ==Gabriella??. I am really grateful to you for such great explanation of the physics driving the hardware.

Where does the value of the speed come from? If I wanted to run a bigger motor (with a different V source nd controller) would the scale still be between 0 and 255?

Hi Paul, I am seriously following your Arduino videos in sequence. Say Hello to Rose. I am getting a humming nice coming form my DC motor even after turning the power OFF on the power supply module. Is this normal or the DC motor is defective?

rose thanks Ronald have a good one!!!!!

I also had fun with a recent purchase of a tachometer and seeing the change in speed (RPM) of the motor with this tutorial - Oh and Homework done :)
