The project is originally designed as LED calculator but the addition of a rotary encoder to set the target system voltage results to adjusting the LED brightness using the potentiometer. By turning ...

The TVOERH080P is a three-channel, lensless reflective optical encoder chip with an integrated infrared LED, enabling an exceptionally compact design. Its high-density photodiode (PD) phase array ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

It's just that their speed varies least from no load to full load of all ac-induction motors. Other induction-motor types don't even come close to matching the speed regulation of these motors. Yet, ...
