First, upload the following PWM sketch to your Arduino Uno r3/Nano v3 and connect a 10mm water-clear green LED to D9. const int ledPin = 9; // Test LED wire to D9 void setup() { // Set the pin as a ...

The nano sensor interface presented ... In short, the simple code excites the onboard LED (D13) to let you know that the program has started. It then sets up for sleep mode and goes to sleep. When the ...

the stand’s onboard Arduino does both automatically. Pressing the red button on the stand starts a countdown procedure complete with flashing LED, after which a relay is used to energize a ...

To the human eye, it looks like multiple LED’s are lit up simultaneously. [Alex] planned to use an Arduino to control this display, but it doesn’t have enough outputs on its own to control all ...

At the heart of this project is an Arduino Nano, based on the Atmel ATmega328 (for the Nano 3.0) or ATmega168 (Arduino Nano 2.x). Basically, using a finger clip, an analogue… ...
