Arduino is a network for open-source electronics focused on a technology that is easy to use. By giving a list of instructions to the microcontroller on the board, you can tell your board what to do.
Arduino was the brain behind thousands of projects over the years, ranging from everyday objects such as battery chargers to complex scientific devices like portable Electrocardigraphs(ECG). Arduino was founded as a convenient tool for easy prototyping at the Ivrea Interaction Design Institute, aimed at students without an electronics and programming background. All Arduino boards are completely open-source, allowing users to create them freely and eventually improve them to suit their specific needs. The software is also open-source and is developing worldwide through user inputs. Arduino has been used in numerous different projects and programs, due to its easy and open user experience. To starters, the Arduino software is simple to use and versatile enough for advanced users. Arduino is an important tool for learning new things.
Some of the Best Arduino Projects
Arduino Robot Arm
A robotic arm formed of 3D printed parts, joints to servo motors and operated using an Arduino Nano. We can use a smartphone and a specially made Android application to wirelessly manipulate the robot arm. The robot arm has Five degrees of freedom, so Five servo motors are required, plus the added servo of the gripper system. The MG996R servos were used for the first three points, the waist the shoulder and the elbow. The smaller SG90 micro servos were used for the other two axes, which is the wrist roll and wrist pitch and also on the gripper. The HC-05 Bluetooth system was used to connect with the device. The movement of each servo or axis of the robot arm can be manually controlled using the sliders in the device. We can also log each position or step using the “Save” button and then the robot arm can run and repeat these steps automatically. We can interrupt the automated process with the same button as we can restore or erase all measures so we can write new ones.
Arduino Alarm System
If you’ve ever thought of developing your own security system, this concept is a good starting point. The ultrasonic sensor is used here to detect movement. The warning will be triggered if a person or entity moves in front of the detector. You will need to enter a password using a keypad to deactivate the alarm. Upon clicking the A button, the alarm will sound in 10 seconds. This uses an ultrasonic sensor to identify objects, and a buzzer begins emitting a sound once the alarm senses it. We need to insert a 4-digit password to end the alarm. The standard password is 1234, but we can change it as well. We access the password update list by clicking the B button where we first need to enter the existing code to start and then enter the new4-digit password. Once the password is modified, we can only stop the alarm by entering the new password the next time we activate the alarm. When we type an incorrect password, we will receive a message that we must try again.
Arduino Wireless Weather Station
This design concept from Arduino is rather realistic as it includes calculation of indoor and outdoor temperature and humidity. It is based on the DHT11/DHT22 sensor, the wireless communication NRF24L01 transceiver module, and the DS3231 RTC. For display purposes, we can use either a 16-inch LCD character or a 3.2-inch TFT touch screen. The outdoor unit can be powered by batteries and an AC converter can be used to power the indoor unit. The outdoor unit tests the temperature and humidity and the measurements are sent to the central indoor unit. Here, together with the date and time values from the DS3231 real-time clock unit, these values are written on the LCD. We can also use the SD Card unit to store the data on a Micro SD card.
Home Automation using Arduino
Home automation for smart homes is today one of Arduino’s most popular projects. The goal of this project is to remotely monitor anything in your house, such as lighting, appliances, heat, security devices, and so on with a single device or your smartphone. So the idea here is to have a master unit that includes a touch display and several slave units that execute master commands. We can use the NRF24L01 radio frequency modules as far as wireless communication is concerned, and each slave unit can have different functions such as temperature monitoring, power outlet control, light control, security alarm, etc. There are, of course, loads of options and configurations to use the Arduino board to create a home automation network. You will switch and connect more apps at all times. You can also use your mobile to make a Bluetooth connection so you can monitor all of this.
Android Smartphone Controlled Power Outlet Using Arduino
The first step in home automation is managing your home power outlets via a smartphone.
Together with the Arduino panel, you only need two components for this design. You can use 220/110V AC to 5V DC converter to power the Arduino and the relay. You can attach and monitor your power outlet using your mobile with Bluetooth. Either you can use some already created software from the Play Store to power Arduino or you can make your own custom app. It is also possible to monitor the power outlets through voice control orders.
