SunFounder has sent me a review sample of the Fusion HAT+ Raspberry Pi expansion board designed for motor and servo control ...

A small portable device featuring timer, clock, and calendar functions, equipped with a simple and functional interface and a truly long battery life.

Third PWM fan goes full speed, RPM controls not working and changing pins also doesn't tho 9th and 10 pin works fine. It seems that app only likes 9th and 10th pin. The Arduino I am using is Arduino ...

Figure 1’s negative constant current source has been a textbook application for the LM337 regulator forever (or thereabouts). It precisely maintains a constant output current (Iout) by forcing the ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Power management leader, Kinetic Technologies, is expanding its portfolio with the introduction of KTB2140. This single-chip, highly integrated active-clamp ...

The Adafruit Metro RP2350 is a Raspberry Pi RP2350 development board that closely follows the Arduino UNO form factor for compatibility with existing Arduino shields. Key features include 37 GPIOs, a ...

This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of the motor ...

// 1) Read OEM push buttons to set the mode (33 RPM, 45 RPM, 78 RPM, Reverse, Start/Stop. // 2) Set the PWM to the H-bridge driver (L298N) via arduino PWM output based on the hall sensor RPM speed ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...
