Nettet29. sep. 2024 · To blink an external LED with our ESP32 then we need to follow the following schematic diagram. Take note of the Anode and Cathode pins of the LED and don’t forget to add the 220 Ohm current limiting resistor to prevent our LED from being busted. The code for the ESP32 is below. NettetLook up the ESP32's pin source current limit and confirm that it's greater than your LED current limit. This will likely be something on the order of 20 mA, but it's good to know. Look up your LED's forward voltage. We'll call this Vf. This is the voltage drop across the LED and is related to the LED's color. For red it's typically around 1.2V.
