Arduino code is written in C++. The second step is to connect your Arduino to a computer via a USB cable and launch the Arduino IDE. Head to theToolsmenu and hover over ‘Port‘ to see if your Arduino was detected. If not, follow the link in the paragraph above for more information....
If you do understand it and get it working, try adding in a second LED to the mix and get them blinking at different rates. More information on this subject can be found on Adafruit Industries website, where Bill Earl has provided a three-part series on multi-tasking your Arduino—even ...
Arduino is an open source prototyping board which is made around ATmega328P; it has 14 GPIO (general purpose input output) pins, out of which 6 pins has capability to do analogue functions, all the 14 pins has the capability to digital functions. A USB 2.0 type B placed right corner of...
A Line Follower Robot (LFR) is one of the most popular Arduino robotics projects that teaches core concepts of automation and sensor integration. This step-by-step guide will show you how to build a professional-grade line follower robot using Arduino UNO, with complete code explanations and tr...
Example code of how to use Arduino interrupts Below the example code of LED blinking in which the interrupt function is used to understand more clearly. const byte ledPin = 13; Led is attach on the board of input pin 13. const byte interruptPin = 2; ...
Arduino Code for Interfacing MQ-3 Gas Sensor Module The code for theArduino MQ-3 alcohol sensor moduleis simple. We're simply reading the analog data from the sensor and adjusting the brightness of the LED to match the data. Please keep in mind that we are merely processing the analog dat...
In this tutorial we will learn how to build an Arduino Mecanum Wheels Robot which is capable of moving in any direction. The unique mobility of the robot...
Arduino Code for Decimal to Hexadecimal Converter Below given is the Arduino code that converts a user input number to hexadecimal: void setup(){ Serial.begin(9600);//initialize serial communication at9600baud } void loop(){ long decimal_input; ...
advantages and disadvantages associated with using it. One of the most common errors encountered with Arduino is the “Does not name a type” error. This can be frustrating to troubleshoot, but understanding some of the pros and cons of this error can help you better understand how to fix ...
Let’s break down the code to help you understand each part. We created two variables — push_btn_pin and pushBTN_state. push_btn_pin, which denotes digital pin 8 connected to the push-button in the circuit, stores the current value (state of the push-button) of the push-button. pu...
