What do you need to control a 5V relay module?
What do you need to control a 5V relay module?
Similarly for PNP type relay modules, an active low signal, activates the relay and an active high signal deactivates the relay. To control a 5V single-channel relay module with any microcontroller, we need to use a GPIO pin as a digital output pin. Digital output pin provides an active low and active high signal to control pin of relay module.
Can you control a relay module with Arduino?
Controlling a relay module with the Arduino is as simple as controlling an output – you just need to send HIGH or LOW signals using an Arduino digital pin. With the relay module you can control almost any AC electronics appliances (not just lamps).
What are the pins on the relay module?
The six pins on the left side of the relay module connect high voltage, and the pins on the right side connect the component that requires low voltage—the Arduino pins. The high-voltage side has two connectors, each with three sockets: common (COM), normally closed (NC), and normally open (NO).
Are there different ways to control electronic relays?
There are plenty of ways to use relays, and each method can achieve several different results. Check out this step by step guide to figure out what you need. Skip to content Search POPULAR SEARCHES:

What kind of voltage does a relay module need?
There are other relay modules that are powered using 3.3V, which is ideal for ESP32, ESP8266, and other microcontrollers. The following figure shows the relay module pinout. The six pins on the left side of the relay module connect high voltage, and the pins on the right side connect the component that requires low voltage—the Arduino pins.

How is a relay used to control a switch?
A relay is an electromagnetic switch that can be operated by a smaller current to turn on and off a much larger current. Relays consist of two isolated circuits, one control circuit, used to control the switch and the other circuit containing the switch.
