Press the button. You can now use ‘digitalWrite’ or other other functions to switch on an LED, relay, adjust PWM duty cycle (for example, increase the brightness of a lamp) whenever the button is pressed.A simple way to test this is to use an ‘if’ statement to check the value ...
buttonState = reading; if(buttonState ==HIGH) { relayState = !relayState; } } } digitalWrite(relayPin, relayState); //change the last state of button lastButtonState = reading; } After uploading the sketch, you can control the relay and LED with the button. Code The debounce of push bu...
Description: These are collections of pre-written code that make it easier to control complex hardware or perform common tasks. Utility: Libraries provide a simple way to interface with hardware, but they can sometimes be inefficient and limit access to hardware features due to their high-level ...

Relay Module is a versatile and reliable solution for controlling various devices with capacitive or resistive touch screens. Designed for use with Arduino, this module offers a simple and efficient way to integrate touch-based control into your projects. Whether you're working on temperature control...
To control the "box" we have to tell it what hardware to use. We must tell the "box" how to manipulate the gates and hardware. that is what machine code does. I am using compiler Arduino-1.6.3. Results may vary with other compilers or a non-Nano Arduino board. Fig. 1 shows the...
