Here is a motor speed sensor module ... based tacho meter or similar circuit/device. The wiring of the hardware turned out to be deceptively simple. At the heart of the circuit is the OS25B10 ...

That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed Control ... test circuit uses six 2N2222 transistors to protect the Arduino from ...

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 ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor ... area of the Arduino sketch. In the next project I will ...

torque and speed. Implement the motor and accompanying rotary sensor into a motor control circuit in both hardware and software. Add a motor and motor control circuit into a microprocessor based ...

I was planning to use the opto-coupler speed sensor as part of a motor speed control – making the motor into the VCO ... then come up with a circuit that tracks the voltage across the external ...

This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors (see the figure). The circuit can find applications in light-tracking ...

The Arduino has been used for many purposes, and “shields” are available to make many common tasks easier. However, [Nick] wanted a stackable motor driver shield, so he build one himself!.
