Step 2:Plug the Anode (+) of the LED to 220 Ohm resistor to digital pin 10 of the Arduino. It is better to take common Ground for all, and you can connect the Arduino ground, and cathode of the LED to the breadboard. With this connection, you can turn ON and OFF the LED using...

The module contains four 7-segment LED numeric displays. These digits can be turned on and off independently. Each of the four digits in the module uses its own common cathode (or common anode) connection point. It means that every segment (line) shares the same anode (or cathode) connecti...
(currentLine.endsWith("GET /H")) { digitalWrite(LED_BUILTIN, HIGH); // GET /H turns the LED on } if (currentLine.endsWith("GET /L")) { digitalWrite(LED_BUILTIN, LOW); // GET /L turns the LED off } } } // close the connection: client.stop(); Serial.println("Client ...
Set up a network connection between an Android device and Arduino. Configure and run Simulink models for Android device and Arduino to remotely control the brightness of the LED on the Arduino. Prerequisites Before you start with this example, you must: ...
Hardware Connection Connect the long leg (anode) of the LED through a resistor to the D1 (GPIO 5) pin on the NodeMCU, and the short leg (cathode) directly to GND. The resistor is used to limit the current flowing through the LED to prevent damage. ...
