Let’s learn how to read a pushbutton using Arduino’s digital input! We’ll connect up a simple circuit using a solderless breadboard and use some simple Arduino code to control a single LED. So far you’ve learned to control LEDs with code, which is one use for Arduino’s outputs. This lesson builds on outputs by adding an

An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This guide demonstrates how to utilize a switch to activate one of

An if statement allows you to choose between two discrete options, TRUE or FALSE. When there are more than two options, you can use multiple if statements, or you can use the switch statement. Switch allows you to choose between several discrete options. This tutorial shows you how to use switch to turn on one of several

The popularity of Arduino boards has skyrocketed in recent times, thanks to the growing demand for automation in the market. These microcontrollers have become the go-to option for beginners looking to embark on their project-building journey, offering unparalleled ease of use and a wide range of options. Arduino has released several common boards that make

This example demonstrates one techinque for calibrating sensor input. The Arduino takes sensor readings for five seconds during the startup, and tracks the highest and lowest values it gets. These sensor readings during the first five seconds of the sketch execution define the minimum and maximum of expected values for the readings taken during the

A potentiometer is a simple knob that provides a variable resistance, which you can read into the Arduino board as an analog value. In this example, you’ll connect a poterntiometer to one of the Arduino’s analog inputs to control the rate at which the built-in LED on pin 13 blinks. Circuit image developed using Fritzing. For

This example demonstrates the use of INPUT_PULLUP with pinMode(). It monitors the state of a switch by establishingserial communication between your Arduino and your computer over USB. Additionally, when the input is HIGH, the onboard LED attached to pin 13 will turn on; when LOW, the LED will turn off. Circuit image developed using Fritzing. For more
