This code results in a LED (connected to pin 13) blinking on and off repeatedly, with each state (on and off) lasting for one second. More Arduino Tutorials
To start, we will work on blinking an LED, the Hello World of microcontrollers. It is as simple as turning a light on and off. Establishing this important baseline will give you a solid foundation as we work towards experiments that are more complex....
Arduino Code - Blink Multiple LEDs To blink multiple LEDs simultaneously, we can't rely on the delay() function. This is because using delay() blocks other code execution, preventing us from blinking multiple LEDs at the same time. Instead, we utilize the millis() function to manage time...
HC-05 has a red light emitting diode (LED), which indicates the connection status with the Bluetooth. Before connecting to the HC-05 module the red LED blinks continuously in a periodic manner. When it gets connected to any other Bluetooth device, its blinking slows down to two seconds. Th...

If everything worked, the onboard LED on your Arduino should now be blinking! You just programmed your first Arduino! Note:Depending on the architecture and development board, the built-in LED may be defined on a different pin. You may need to adjustLED_BUILTINor pin13to a different value...
In this post I have explained how to generate sine wave pulse-width-modulation or SPWM through Arduino, which can be used for making a pure sine wave inverter
The Blink sketch, which comes with Arduino, is used as an example for recipes in this chapter, though the last recipe in the chapter goes further by adding sound and collecting input through some additional hardware, not just blinking the light built into the board.Chapter 2covers how to str...
