30 Arduino Compatible Modules

Nowadays electronic devices are becoming compact, flexible, and cheap that are capable of doing more functions as compared to their predecessors. A Microcontroller was introduced as a new innovation in the electronics industry. Designed with the purpose of making our tasks easier, with minimum effort, and giving maximum output.

Let’s take a look at the world of Arduino modules in this blog. There are a variety of Arduino Sensors and Modules on the market. To make things easier, I put up a list of some of the most helpful Arduino Sensors and Modules. 

What are Arduino Modules?

Arduino is an open-source hardware and software corporation, initiative, and user community that creates single-board microcontrollers and microcontroller kits for the creation of digital devices. It is critical to understand the pin configuration of the Arduino board before beginning any project based on it. An Arduino Module incorporates all of the essential components and connections for a sensor (or a device) to function and provides you with a ready-to-use product.

Consider the Infrared Obstacle Avoidance Sensor Module, which is both simple and effective. It comprises of an IR LED, a Photo Diode, an Op-Amp, a Potentiometer, a couple of passive components, and a connector.

The module takes care of the “Sensor” side of the circuit, such as current limiting resistors, decoupling capacitors, connections, connectors, and so on, so all you have to do is attach it to an Arduino board and you’ve got yourself an Obstacle Avoidance Robot.

  • Two Colour LED Module

Let’s start with an LED Module because the first Arduino program you’ll build will be to blink an LED. This is a two-color LED Module, which has a three-pin two-color LED, as the name implies.

A popular two-color LED is red and green. To control the brightness, connect them to the Arduino’s PWM pins. Current limiting resistors must be connected. I believe the current limiting resistors should have been built into the module itself.

  • RGB LED Module

After using a Two-Colour LED, the next obvious step is to use an RGB LED. A 4-pin RGB LED, three current limiting resistors, and connections make up an RGB LED Module.

  • Push Button Module

One of the most basic input devices for Arduino is a momentary push button. Along with the connectors, the Push Button Module includes a momentary tactile push button and a pull-up (or pull-down) resistor.

If a pull-up resistor is utilized, logic HIGH is detected when the button is not pressed and logic LOW is detected when the button is hit. Opposite in case of the pull-down.
