根据输入电压的值,我们给出了一些条件来控制LED条形图LED。您可以在代码中检查以下条件: if (input_voltage < 0.50 && input_voltage >= 0.00 ) { digitalWrite(2, HIGH); delay (30); digitalWrite(2, LOW); delay (30); // when the voltage is zero or
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...
