Introduction

Relay is an automatic switching element with isolation function, which is widely used in remote control, telemetry, communication, automatic control, mechatronics and power electronic equipment, and is one of the most important control elements. The traditional relay module has complicated wiring and is not friendly to novice makers or electronic enthusiasts. The CQRobot relay module simplifies the wiring of traditional relays. The input terminal is equipped with an adapter, which is compatible with most power supplies and battery boxes. , DC power supply, power bank, etc. While simplifying the wiring method, the functions of the relay NC and NO are retained, and only a simple adjustment of the toggle switch is used to switch between normally open and normally closed modes.

CQRobot's latest simple relay module uses a standard Ocean sensor interface and supports a wide voltage input from 3.3V to 5.5V, making it easy to Compatible with Raspberry Pi, Micro:bit, Arduino and other main control boards. Satisfy your needs in robot control, lighting control, smart home, surveillance and other control applications.

Testing for RaspberryPi

  • Download the Sample Code for RaspberryPi.
  • Upload the code to the RaspberryPi.
  • Wire according to the Connection Diagram.
  • Execute the following command in the terminal to run the program.
ls
gcc TS1818.c -o TS1818 -lwiringPi
sudo ./TS1818
