While there is a time and place for wirelessly controlled devices, sometimes you want something you can just reach out and ...

FM (Frequency Modulation) is a popular method for transmitting audio signals wirelessly over a radio frequency carrier wave. In FM transmission, the frequency of the carrier wave is varied in ...

Arduino library for the KY-040 Encoder. This library allows the user to connect one or more encoders to any of the interrupt pins supported by your board. The user may then add rotaries that will each ...

The product we are reviewing today is the “MaTouch ESP32-S3 Rotary IPS Display with Touch 2.1” ST7701″ from Makerfabs which offers an alternative to the MaTouch_ESP32-S3 4-inch Display Demo Kit that ...

A rotary encoder is a type of electromechanical position sensor that can be used to identify the angular position of the rotary shaft. This type of sensor or module generates an electrical signal ...

In industrial automation and control, PID controller has become one of the most reliable control algorithms that can be implemented to stabilize the output response of any system. PID stands for ...

I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...
