A digitally controlled electronic device is an electronic device that uses digital signals for control and operation. Here are some common digital controlled electronic devices:
1. Microcontroller: A microcontroller is an integrated circuit that contains components such as a central processing unit (CPU), memory, and input/output interfaces. Microcontrollers can perform digital control tasks such as controlling motors, sensors, and other external devices.
2. Digital Signal Processor (DSP) : DSP is a microprocessor specially designed to process digital signals. It can perform high-speed digital signal processing tasks such as audio and video processing, communications, and control systems.
(3) Programmable logic controller (PLC) : PLC is a digital control device for industrial automation control. It can be programmed to achieve a variety of control tasks, such as machine control, process control and automated production lines.
4. Digital counter: Digital counter is a digital control device for counting and timing. It can be used for counting, measuring time and frequency, etc.
5. Digital potentiometer: Digital potentiometer is a digital control device used to adjust the resistance value. It can control the size of the resistance value through the digital signal, so as to achieve the adjustment and control of electronic equipment.
6. Digital multimeter: Digital multimeter is a digital control device used to measure parameters such as voltage, current and resistance. It can display the measurement results by digital signal, and has the advantages of high precision and convenient use.

In short, digital control of electronic devices with high precision, fast speed, high reliability, strong programmability and other characteristics, widely used in industrial automation, communications, electronic equipment and medical equipment and other fields.
