Arduino circuit with a push button and 3 LEDs; All LEDs on when button is pressed, all LEDs off otherwise. Setup pins; Power on/off LEDs depending on button’s state; Improve the code with arrays and functions. Create defines and a global array; Init the pins; Read the button’s state and power on/off all LEDs

Dec 29, 2014 · Here is a toggle code for one push-button. By duplicating the toggle part, you can use it for as many LEDs as you want. // Button toggle with extreme reliability! const int led1Pin = 13; // LED pin number const int button1 = 10; int led1State = LOW; // initialise the LED char bstate1 = 0; unsigned long bcount1 = 0; // button debounce timer.

Aug 23, 2017 · I see the buttons are paired with a resistor. Wire your buttons between the pin and ground and enable the internal pull-up, then you can lose the external resistor. Note that buttons are active LOW in this case, so logic is reversed.

Dec 21, 2012 · Hey I'm currently trying to make a buzzer system with 3 push buttons, 3 LEDs, and 1 buzzer. The way I want to set it up is so that if you press one switch it will deactivate the other two, light up the LED for 30 seconds and activate the buzzer for …

Apr 3, 2018 · We’ll see here how to control LEDs and how to select different functionalities of the code using only one button. This summarize in a simple way what you could encounter working on a robot: Brain (Arduino board), Senses (sensors, here a button) and Ouputs or actuators (here symbolized by LEDs).

In this guide we will use 3 LEDs and one push button. For this project, we will need : 220 Ohm value resistors are for the 3 LEDS, 1K Ohm value resistor is for the push button. We will add the pushbutton on pin 7, first LED1 on pin 8, second LED on pin 9 and third LED on pin 10 of Arduino board. This will be the connection :

Apr 27, 2014 · I am writing a simple program that is supposed to have 3 buttons control 3 LEDS when the button is double clicked. The code itself works fine for a single button + LED and for 2 buttons + 2 LEDS. When I put the 3rd one in it won't work.
