In this tutorial, we will learn to use a 16×2 LCD with Arduino. The following image shows the pinout of 16×2 LCD. Components required for this project: Name Quantity Component U1 1 LCD 16 x 2 R1 1 Potentiometer 10k U2 1 Arduino Uno R3 R2 1 220 Ω Resistor 🛠️ Dive into our collection…
In this tutorial, we will create a sketch in which the RGB LED emits only the green light that turns on and off gradually. In the second example, you will see that red, green and blue lights also turn on and off gradually. This project is suitable for school students and beginners. For this experiment,…
In this tutorial, we will use the digitalRead function and learn how to read a digital pin. In our case, the digital sensor that will be read will be a common button/reset tactile switch that when pressed will turn on the LED. Components required: Name Quantity Component U1 1 Arduino Uno R3 D1 1 Green…
In this tutorial, we will use a servo and a potentiometer to make the servo motor change its position according to the given value given by the potentiometer. Components used in this project: Name Quantity Component U1 1 Arduino Uno R3 Rpot1 1 10 kΩ, Potentiometer M1 1 Servo Arduino Sketch:
This is just a simple Arduino project comprising Arduino, LM35, and I2C LCD. It displays the room temperature on the I2C LCD and the serial monitor. The project is suitable for beginners and can be used for school projects. In the past we have done several projects using LCD and LM35, please check the projects…
This is a simple motion sensor project using Arduino. A 220V AC lamp is connected to a 5V relay and the relay is activated once the motion sensor senses motion and sends a signal to the Arduino. List of materials Arduino Uno ( Rev 3 ) Sensor ( PIR ) HC-SR501 Keyes SRD-05VDC-SL-C Relay Module or any 5V relay module…
In this tutorial, we will learn how to use a servo motor. A Servo is a motor capable of making maximum rotations of 270° and is widely used in robotics and modeling. It requires a library (<Servo.h>) that is already installed on the Arduino IDE software. In this tutorial, we will vary the position of…
In this project, we will learn to experiment with LDR and a buzzer. The output of this experiment is sound with different frequencies that are produced depending upon the light falling on the LDR/photoresistor. STEPS – Connect the negative black wire of the buzzer to pin GROUND and the black positive to the digital pin…
In this tutorial, we will learn to use a potentiometer with Arduino. It allows us to change its value by turning a small knob, the analog value read by Arduino will enable us to do our flashing of the LED depending on the value read. Steps: -Connect the LED as shown on the image. -Connect…
The photoresistor or LDR is a resistor that varies its value according to the light falling on it and therefore it can be used with Arduino to create innovative and more complex projects. Connect the LED and LDR to Arduino as shown on the image. List of components: U1 1 Arduino Uno R3 R1 1…
This is the most basic project for Arduino beginners. Almost everyone starts Arduino with this project. The output of this project is a blinking/flashing LED. Insert an LED on your breadboard and connect it to your Arduino using wires as shown on the image. We can also use the inbuilt LED present on the Arduino…
This project shows a combination of analog and digital circuits ready for interactive sound production! The project uses Arduino and NE555.
We are now selling BLUE colored DIY Arduino kit. You know that there are several versions of Arduino hardware. Hobbyists have also made Arduinos on strip boards giving different looks. Here’s one more Arduino, that is a simple do-it-yourself (DIY) kit. It is just like any other Arduino UNO board. However, it does not…
In Amarino shield version 3.0, there are headers for 3 different bluetooth adapters. a. General Bluetooth Adapter – Cheapest adapter available at www.buildcircuit.net. RECOMMENDED ! b. BlueSMiRF– Bluetooth Mate Silver– More expensive adapter available on sparkfun.com. c. BlueSMiRF Gold – The most expensive adapter available on sparkfun.com. – Whichever Bluetooth adaptor you are using, the baud rate of Bluetooth adapter should match…
The 4 channel RF receiver and transmitter can be used with or without an Arduino. You can connect relays to the receiver outputs to control it wirelessly.
See page 1 Remaining part of assembly of line following robot… Fix the nut bolt set on the PCB Solder the photo resistor/LDR as shown on the image.Make sure that the LDR is at least 5mm above the ground or spot where you are placing the robot. Solder the transparent 5mm LEDs. The LEDs should…
