This opens our LED_BLINK project that we created inside the EXPLORER tab. As you can see there are several folders inside our project folder (LED_BLINK). This is the same for every project which you will create through ESP-IDF Explorer. Themainfolder contains the source code meaning the ma...
For my "SparkFun ESP32 Thing" I only commented out the: Code: Select all /* // check for the presence of the shield: if (WiFi.status() == WL_NO_SHIELD) { Serial.println("WiFi shield not present"); while(true); // don't continue } */ and changed to Pin5 as Output..1...
In this tutorial, we will learn how to use GPIO pins of the ESP32 devkit with LED blinking examples using Arduino IDE. Whenever any beginner starts learning about any microcontroller-based development board, Experts always recommend beginners to start with an LED blinking example which is also kn...
we are using the ESP32-S2 DevKit M1 v1.0 (ESP-S2-MINI-2; `XXN4R2`) and are encountering strange behavior on some of them. Instead of the on-board WS2812 Led going white when told so it will show red. All of the other primary colors seem to work (red, blue, green). ...
