Ideas for Arduino Projects


The following section of this article contains Arduino project ideas based on my detailed tutorials on various sensors and modules, as well as your suggestions from the comments section below.

For each project idea I will point out the required components as well as the particular tutorial for each of them.

Arduino Wireless Weather Station

This Arduino project idea is rather practical because it features indoor and outdoor temperature and humidity measurement. It is based on the DHT11/ DHT22 sensor, the NRF24L01 transceiver module for the wireless communication and the DS3231 RTC. For the display we can either use 16×2 character LCD or a 3.2 inches TFT touch screen.

Android Smartphone Controlled Power Outlet Using Arduino

Controlling your home power outlets via a smartphone is the first step in home automation. You can easily make your own Arduino controlled power outlets utilizing the knowledge you can get from my Arduino tutorials.

Android Smartphone Controlled Power Outlet - Arduino Projects Ideas

 

For this project you just need two components along with the Arduino board. An HC-05 Bluetooth module and a 5V Relay module for which I already have detailed tutorials. For powering the Arduino and the relay you can use 220/ 110V AC to 5V DC converter.

Using your smartphone you can connect and control your power outlet via Bluetooth. You can either use some already made apps for controlling Arduino from the Play Store or create your own custom made app. In this way we can also control the power outlets through voice control commands.

Difficulty: Advanced

Home Automation using Arduino

Home automation is one of the most popular Arduino projects nowadays. The goal of this project is to remotely control anything in your house like lights, appliances, temperature, security devices and so on, with a single device or your smartphone.

In order to make such a project we need decent amount of knowledge in Arduino. The following home automation concept that I suggest is based on my detailed Arduino tutorials for various sensors and modules.

Home-Automation-Arduino-Projects

So the idea here is to have a master unit which includes a touch display, and several slave units which will execute commands coming from the master. As for the wireless communication we can use the NRF24L01 radio frequency modules, and each slave unit can have various functions like, temperature monitoring, power outlet control, lights control, security alarm and so on.

Of course, there are endless possibilities and combinations for building a home automation system using the Arduino board. You can always change and add more devices. You can also make a Bluetooth communication so you can control all of this using your smartphone etc.

Arduino Robot Arm

When it comes to automated manufacturing, robotic arms play big role with so many applications. They are often used for welding, assembling, packing, painting, pick and place tasks and much more.

Building an Arduino controlled robot arm can be both easy and difficult. It all depends on the control complexity and the results that we want to get. This project suggestion will keep things simple.

Robot Arm - Arduino Projects

You can make a 5 DOF robot arm with just 5 servo motors and an Arduino board. As for the control you can use simple potentiometers for each motor, or pre-program the movements of the arm. On the other hand, for the construction, the simplest solution is to use a card board. Of course, you can make the construction much better if you are using sheet metal.

Note that you should use separate power supply for the motors. The Arduino will only send the PWM signal to the motors.

Difficulty: Advanced

Arduino Gesture Control

The idea for this project is to remotely control an Arduino project using hand gestures. Let’s say we want to control the Arduino Robot Car that we mentioned above. So instead of the joystick we will use an MEMS module for the control.

Arduino Gesture Control Arduino Project

We can use the GY-80 module which features an accelerometer, a gyroscope and a magnetometer. The data we get from these sensors can be used for controlling the steering of the robot car. As for the wireless communication we can use the NRF24L01 transceiver modules.

You can also check my Mechatronics Final Year Project where I used a similar method for controlling a 3D model in Matab Simulink.
