This repository contains my NodeMCU Arduino examples, each folder contains the .ino file an image of the wiring setup and any notes to explain the setup where required. As I’m new to coding if anyone ...

This ensures your arduino IDE is setup properly. Contributing. For minor fixes or new examples, submit a pull request. If you submit new examples, try to make the example only do a single thing. Of ...

Arduino Micro SD Card Module Circuit Connection Diagram. Now that we have completely understood how a Micro SD Card Module works, we can connect all the required wires to the Arduino and write the ...

Connect the 2N2222 transistor to the pin3 of the Arduino with a resistor connected to the base of the transistor and collector terminal to the 5V of Arduino Uno. Connect a small bulb between the ...

We can use the ADC of the Arduino to process the signal and we can light up some LEDs to show the intensity of the sound received by the microcontroller. The connection of the circuit is also very ...

Get the example sketch from the Short Circuits website, and copy it to a new Arduino IDE sketch window. I am preparing to upload this sketch to the Motherboard via the FTDI module. As with a regular ...

Before the software part, let's first set up the circuit to connect the LED to the Arduino. The completed circuit should look like Figure 2. Figure 2. Circuit for a Single LED Blink Next, in your ...
