Learn how the UART serial communication protocol works with the ESP32 using Arduino IDE: the basics of UART, default and custom UART pins, basic functions, communication between boards.
Send configuration messages or initialization commands when MegunoLink connects to your Arduino sketch using the SerialConnection.
I'm going to explain how to use note on, note off, velocity, and pitchbend in this instructable, since these are the most commonly used commands. I'm sure you will be able to infer how to set up the others by the end of this. Step 3: Send MIDI Messages With Arduino- Hardware Pa...
while programming Arduino uses serial ports to load programs from the Arduino IDE. If these pins are used in wiring, the program will not be loaded successfully to Arduino. So you have to disconnect wiring in Rx and Tx each time you burn the program to Arduino. Once the program is loaded...

In this tutorial, we have learned how to use the SIM800L module and ThingSpeak’s API to send data from an Arduino board to the internet. We have set up the SIM800L module and used AT commands to connect to the internet and send HTTP requests. We have also set up a ThingSpeak chann...
