This project demonstrates a simple Arduino circuit that makes an LED blink on and off. The circuit uses an Arduino UNO, an LED, a resistor, and connecting wires. Connect the longer leg (anode) of the ...

Connect the four LEDs to Arduino digital pins 7, 8, 9, and 10, each with a 220Ω current-limiting resistor connected in series. Connect the other leg of each LED to a common GND pin on the Arduino.

The combined LED/driver chip on the LED is the extremely compact WS2812B – an improved WS2811 LED driver integrated directly into a 5050 RGB LED – which enables higher LED densities. On the right of ...

Push Switch (S1) input point is at pin 9 of the Arduino. Connecting the display pins directly to Arduino I/O pins is not a good practice. For testing purpose only one 330 Ohm resistor (R2) is added ...

While it’s great to look at professional maker projects that use motion tracking cameras or giant 3D prints that break the bank, it’s also nice to look at simple Arduino builds too. This ...

Raspberry Pi GPIO control with Arduino Cloud is a crucial aspect of many Internet of Things ... The first step is to physically set up the Raspberry Pi by connecting it to an LED and a push button.

When you read “Arduino wristwatch”, you fall into the trap of envisioning an Arduino UNO clumsily strapped to someone’s wrist. [Marijo Blažević’s] creation is much more poli… ...
