Sheet metal intake manifold build
This relay module is 5V active low. Relay output maximum contact is AC250V 10A and DC30V 10A. Standard interface can be directly connected with microcontrollers. Working status indicator lights are conducive to the safe use; 4-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino ... So, connect the 5V and the ground of the Arduino with the 5V and the ground of the relay module. Then connect the signal pin of the relay module with the pin 12 of the Arduino. On the other side of the relay module, we will use the common pin and the normally open pin because we are going to connect the relay in the normally open state. This 8 Channel Relay module can adopt most common range of microcontrollers, such as Arduino, Raspberry Pi, AVR, PIC, ARM with digital outputs to control larger loads devices like AC or DC Motors, Electromagnets, Soleniod, Incandescent light bulbs, Actuators and any another devices that you want to drive with in the relay. This is a 5V 8-Channel Relay interface board, Be able to control various appliances and other equipment with large current. It can be controlled directly by Micro-controller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). Since the Arduino operates at 5V it can’t control these higher voltage devices directly, but you can use a 5V relay to switch the 120-240V current and use the Arduino to control the relay. The Arduino can be programmed to turn on the relay when a certain event occurs, for example when the temperature of a thermistor gets higher than 30° C.
