Tony Goacher] has worked with a lot of cheap brushless DC motor controllers built in China. They can be very cost-effective, ...

Renesas has recently launched the RA2T1 group of low-power motor control MCUs, built around a 64 MHz Arm Cortex-M23, for low-cost single-motor applications like power tools, fans, and home appliances.

This library is to control the I2C PCA9635 PWM extender. The 16 channels are independently configurable in steps of 1/256. This allows for better than 1% fine tuning of the duty-cycle of the PWM ...

This paper contributes to smart greenhouses and IoT (Internet of Things) research. Our pioneering achievement centers on successfully designing, constructing, and testing a 30m2 smart greenhouse, ...

In my previous design idea, a design for a simple GPS disciplined oscillator (GPSDO) 10 MHz reference was presented. A note at the end of that article describes the realization that a frequency ...

I was recently working on an experiment for a new design and was using a function generator. Although new function generators have pretty good frequency tolerance specs, I needed something with more ...

This library is to control the I2C PCA9634 PWM extender. The 8 channels are independently configurable in steps of 1/256. This allows for better than 1% fine tuning of the duty-cycle of the PWM signal ...

Pulse-width modulation (PWM) is a technique for changing the amplitude of digital signals to control devices and applications that require power or electricity. It effectively regulates the amount of ...

The humble ATmega328 microcontroller, usually packaged as an Arduino Uno, is the gateway drug for millions of people into the world of electronics and embedded programming. Some people just can’t pass ...
