In this demonstrative example it is shown how to make a simple web server using an Arduino UNO WiFi to command the switch ON/OFF of a LED.
1. Hardware
- Arduino UNO WiFi
- Led
- 220Ω Resistor
- wire
- Breadboard
2.Circuit
You can use the integrated L LED on pin 13 or use another one, in this case connect the LED anode (usually the longer pin) in series to a 220Ω resistor and connect it to the board pin 13.
After connect the cathode to GND, as shown in the picture.
