Показать описание
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. There are two main types of rotary encoder: absolute and incremental. The output of an absolute encoder indicates the current shaft position, making it an angle transducer. The output of an incremental encoder provides information about the motion of the shaft, which typically is processed elsewhere into information such as position, speed and distance.

Hi, i want to control one dc motor with rotary encoder and wireless communicate with nrf24l01.
For dc motor its need to be have speed and direction control with rotary encoder.
Please help me in cods for transmitter and receiver.

Why does so many content creators use fake computer generated voices, and why does it have to sound like a circus clown ?
