When the switch is open the LED turns on, but when I push the button, the light just dims. This is obviously a very small portion of the project.
HOLD BUTTON TO KEEP LIGHT ON ARDUINO HOW TO
Should I use a button counter, if statements, or while statements? I'm really new to coding and took on a large project I'm not sure how to complete. I don't know how to change the state of the LED back on after the 24 hours. However, if the switch is closed within the 24 hours, the light doesn't turn on and pushing the button does not do anything. Use this code the onAndOff is boolean that has one of the two values (true, false) we put false in it if led is off we put true in it if led is on and we check if its true or false when we press the button if its false then turn the led on and put true in onAndOff otherwise turn off the led and put false in onAndOff. When the button was released at anytime, all LEDs would be off. So 7s after the button was pressed and hold, all 8 LEDs shall light up. When the switch is open, the LED turns on and pushing the button turns it off and stays off for 24 hours then turns back on if the switch is still open and I can again turn off the light with one push of the button. There are 8 LED lights in total, when the toggle button was pressed, 1st LED lights up keep holding/ pressing the button, the 2nd LED lights up after 1sec, the 3rd LED lights up after 2sec and so on. Create and position a high value resistor (such as 10K) between that same button leg and ground. Connect the diagonally opposite leg to Arduino digital pin 2. I have system connected to an Arduino Uno where I want to read whether the switch is open or closed.īased on if the switch is open/closed, I want an LED light to turn on/off. Click to create a wire connecting one button leg to power.
