You can use the following code example to introduce a delay within the circuit. So, the “stayON” variable is utilized to delay() the program execution within the preferred amount of time. Here, once the button is pushed then the relay will be turned ON & after five seconds the relay ...
Note the above code snippet. Press S1 LED1 turns on and stays on. Press S2 and LED1 turns off and stays off. (This could also be a motor control for example.) In each case pressing S1 or S2 returns a 1 or 0; the "if" command does the rest. Another note is the () must be...
Learn how to use relay with Arduino, how relay works, how to connect relay to Arduino, how to code for relay, how to program Arduino step by step. The detail instruction, code, wiring diagram, video tutorial, line-by-line code explanation are provided to

Connect one of the button pins to pin 11 through a ~ 5 kOhm resistor, and the other pin to ground (GND). 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)...
If it is equal or less than what the Arduino is rated to give out, you should have no problems connecting the Arduino directly to the circuit. If, however, the circuit needs more, you will need to use some kind of transistor-driving circuit. The circuit below shows a relay, which is ...
