Why We Use C++ To Code Arduino?
Performance is frequently a significant factor when writing code for microcontrollers. You, therefore, need programming languages that are robust and quick. Among the most potent languages available are C and C++. These are fantastic options for microcontrollers because they are relatively small and stable. The fact that C++ is object-oriented is its most significant “high-level” attribute. An object in such a language is a construct that combines “state” and functional code (the code that performs tasks like calculations and memory operations) with the results of such calculations (or simply values) stored in variables. When compared to older paradigms, object orientation made programming far more productive in most applications since it allowed programmers to use abstractions to build complex programs. So without any delay, let’s start working on the Top 10 Best Arduino Projects for Beginners with Source Code.
How To Choose The Best Project To Learn Faster
Arduino is a fantastic robotics platform. Almost every component or gadget in use today can be connected to and used with it. It’s a terrific way for novices to learn about inputs and outputs and how computers, robots, and mechanical devices may interact with you and the world around them. The projects covered will help you learn about motors, motion sensors, and VEX VR robotics. After uploading the code to the Arduino board, you may access the necessary functionalities. You must translate the source code for your project into a form that the Arduino’s microcontroller can understand. Since the Arduino IDE includes an open-source C++ version, you need not worry about the technicalities. The “Upload” button causes the IDE to start the compiler, which converts your human-readable code into ones and zeros and sends it to the microcontroller over the USB cable. These projects will help you understand Arduino’s variables, functions, and program architecture. Various C/C++ concepts are used in Arduino projects, including variables, constructors, conditionals, functions, operators, and many others.
You will also get to learn about the Arduino UNO board, Voltage Regulator, Power LED Indicator, ATmega Microcontroller, Digital Input/Output, and how to upload code to the Arduino board.
Avr-g++ is the compiler that converts source code into object files. The program is then uploaded into the Arduino microcontroller using an application called AVRDUDE.
Top 10 Best Arduino Projects for Beginners with Source Code
1. Traffic Management System
Traffic Lights and Traffic Signals are signaling tools used to manage traffic flow. They typically stand at intersections, ‘X’ roads, pedestrian crossings, junctions, etc., and alternate who must wait and who must move first. By flashing lights of uniform color, traffic lights will give cars and pedestrians directions. Red, Yellow, and Green are the three hues that are utilized in traffic signals. To ensure efficient and secure traffic flow, the system must be employed to manage the traffic lights. These control systems might be either contemporary solid-state computerized systems with simple setup and maintenance or electromechanical controllers with clockwork mechanisms.

2. Program RGB LED Using Arduino
The RGB LED comprises three distinct LEDs; as the name implies, these LEDs are red, green, and blue. By combining these colors, we may get a variety of additional hues. We may use the analog write function on the Arduino to get different colors for the Arduino RGB led. Once the program has been uploaded to the Arduino board, open the serial monitor to see how the values change as the light intensity changes. According to the LDR Values, the associated LED illuminates in analog mode.

3. Photoresistor Sensor To Glow LED Using Arduino
Arduino UNO is used to power the LDR and LED (Board). It includes a code that was uploaded on the message board. Once everything has been simulated, you can observe When the LDR detects darkness, it will send a signal to the board, supplying power to the LED. Here, a blue LED is used; one LDR is required to get readings. The sensor readings are read by the Arduino using an analog pin. Therefore, the potentiometer we wish to read will be connected to the Arduino’s analog pin.

4. Temperature Monitoring Using Arduino
The Arduino temperature sensor transforms the ambient temperature into electricity. The temperature in Fahrenheit is printed on the LCD screen after further conversions from Celsius to Fahrenheit and voltage to Celsius. A low-voltage temperature sensor is an option. These sensors can handle heavy capacitive loads without losing stability. Additionally, it works well for automotive applications. The features of the temperature sensors TMP 35, TMP 36, and TMP 37 are the same. The TMP 36 sensor’s operating voltage ranges from 2.7V to 5.5V. The system will produce the desired output once you upload the code.

5. Zoetrope
Like a flip book, a zoetrope provides the illusion of a single animated image by rapidly moving several images around one location. However, a zoetrope rotates the images, which are viewed through a slit, as opposed to a flip book, which you swiftly turn the pages of.

6. Mini Musical Keyboard Using Arduino
Here is a straightforward DIY project called Music Player with Arduino, where you can play audio files using an Arduino UNO. This project controls the playback of the audio and supports WAV Audio files. To increase the output power, utilize an extra amplifier like the LM386 integrated circuit. You can add an audio effect to your Arduino Projects Kit by using this project.

The procedure entails loading the data into the data registers that will be displayed on the LCD panel. The instruction register is used to store the instructions from the Register Select. The procedure for displaying characters on the LCD has been made simpler by the liquid crystal library. The 4-bit or 8-bit modes of controlling the LCDs require 7 and 11 Input/Output pins from the specific Arduino board, respectively.

8. Blinking LED Using a Button
It is a straightforward project made with Arduino. An electronic gadget called an LED (Light Emitting Diode) produces light when electricity flows through its terminals. There are many applications for LEDs. In certain electronic equipment, it also serves as an ON/OFF indicator.
The programmer’s delays are completely what drives the blinking setup. After obtaining the code, link the Arduino to the computer using its USB interface. In the software, select the COM port number and board type. Then verify, and after that, upload. then watch your LED as the magic happens.

9. Arduino Ultrasonic Distance Sensor
SONAR uses an ultrasonic sensor to calculate the object’s distance. It uses a frequency of 40KHZ or 40000 Hz to emit the ultrasound. Through the air, the frequency moves and impacts anything in its path. The rays return to the module after bouncing off the object. The HC-SRO4 has four terminals: VCC, TRIG, ECHO, and GND. VCC, or the voltage supply, is +5V. Any of the digital I/O pins on the Arduino board can be connected using the ECHO and TRIG terminals.

When a key is pressed, it is compared to the keys that have already been stored. The lock will unlock if the keys are pressed to coincide with the original password, which is recorded in the EEPROM. The LCD will display “access refused” if the password is incorrect. The existing password will be requested if the “#” key is pushed, and if it matches, the new password will be requested. If not, the password will remain unchanged.
