This instruction is executed only one time. Next is the loop function that sets the pin 13 HIGH (+5V on pin 13), waits a second (1000 ms), then turns OFF the LED (0V on pin 13) and waits another ...

By building this project, you’ll master: Digital input handling – How Arduino reads button states Output control – Turning LEDs on/off programmatically Circuit design fundamentals – Why resistors are ...

🧠 Purpose The default delay () function in Arduino halts the processor, which makes it unsuitable for multitasking scenarios. This project provides a customdelay () function that adds additional ...
