How do you turn an LED on and off with a button on Arduino? We set the pinButton variable as integer 8 and we connect the button at pin 8 on the Board. Then the LED is connected to pin 2 using the ...

Note: This is a non-isolated Arduino-DMX adapter circuitry, so there is no galvanic isolation between the master device and the rest of DMX device(s). The pin 2 (RE) of MAX485 controls whether the ...

#define LED_BUILTIN 13. This indicates digital pin 13 on the Arduino's pins connector (also called a header). But at the same time LED_BUILTIN tells the Arduino to use the actual built-in LED on ...

When the Arduino code sees the button getting pressed, it brings the corresponding LED pin high and starts a fade out timer using the SoftPWM library by [Brett Hagman].

If you want to add a keypad to your Arduino project, the options are pretty limited. There’s that red and blue 4×4 membrane we’ve all seen in password-protected door lock projects,… ...

The down-side of being busy and spending ages in the car commuting is that time for making things is limited. The up-side of not finding time to make things, is that you get more time to ponder the ...

The Adafruit Gemma measures just 1 inch in size and is powered by an ATtiny85 and programmable with an Arduino IDE over USB, allowing you to create those wearable projects of the future.
