Integrate the motor to a machine, based on analysis of motor equations for voltage, current, torque and speed. Implement the motor and accompanying rotary sensor into a motor control circuit in both ...

Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

The hardware is consists of an Arduino microcontroller (here an Arduino Uno R3) and a pre-wired soil moisture sensor module. The soil moisture sensor module , built around the LM393 comparator, gives ...

I was planning to use the opto-coupler speed sensor as part of a motor speed control - making the motor into the VCO block in a phase-locked loop. When ...

His test circuit uses six 2N2222 transistors to protect the Arduino from excessive current. You can see six red LEDs above which are inline with the base of teach transistor.
