![]() We code programming on Sketch – Arduino IDE as code below. Then, we connect parts on breadboard and the arduino as Figure 2įigure 2 circuits connection on breadboard So we use schematic as Figure 1įigure 1 Schematic diagram of The Button becoming Toggle Switch using Arduino We want to control LED ON-OFF by button (as toggle switch). Then, we press it again it will “off” and store status “off” as well. When we press the button “on” it will store status “on” hold, although, we will release. Today we will as push button switch as toggle switch. Now we use the button or switch as a digital input. The LED will delay time turn ON about 10S. ![]() And upload When we press the button LED will glow as we press. How to Program a Push Button with an Arduino Robot Research Lab 1. We test it as Video, first type code on IDE without “delay” command. Afterwards, load a sketch that reads the state of the switch. PinMode(buttonPin, INPUT) // initialize the pushbutton pin as an input:īuttonState = digitalRead(buttonPin) // read the state of the pushbutton value:ĭigitalWrite(ledPin, HIGH) // turn LED on:ĭigitalWrite(ledPin, LOW) // turn LED off: Connect a push button switch to an Arduino Uno or MEGA 2560 in this part of the tutorial. Then for quite some time the code is busy doing those delay calls. PinMode(ledPin, OUTPUT) // initialize the LED pin as an output: 1 Your problem is that the button only gets read at the top of loop. Click Upload button on Arduino IDE to upload code to Arduino. Copy the above code and open with Arduino IDE. Click Install button to install ezButton library. Search ezButton, then find the button library by ArduinoGetStarted. Int buttonState = 0 // variable for reading the pushbutton status On Arduino IDE, Go to Tools Manage Libraries. ![]() Int ledPin = 13 // the number of the LED pin Figure 4 the Simple Button Digital Input code with delay int buttonPin = 3 // the number of the pushbutton pin ![]()
