First steps with Arduino and LEDs

LED Activation and SOS Command with Arduino

Here I will start presenting the first part of our project with ARDUINO, made together with Alex Sanfeliu

We will first start with the materials used for the first things done:

A protoboard

Programmable chip: ESP 8266 MOD

Some black and red wires

Resistors

LEDs

An USB connector

Now before starting programming, we will need to download some stuff to our computer:

We download Arudino IDE or Visual Studio Code to setup the code, we will be using Arduino IDE now

Inside Arduino IDE, we download the configuration of our protoboard and programmable chip, in our case ESP8266

If we use Visual Studio Code, we will need to download Expresif-IDF and PlatformIO IDE as extensions

For the drivers, we will go the the principal page of ESP-32 and download the last drivers of our chip, and then in our computer configuration we will activate them with our chip

Now we can start working with Arduino IDE

First we should test if everything is alright, and we can do this with one of the blinking examples given in Arduino. If everything it's setup well, our LED should blink in differents periods wich we can control

Now we will try to do the morse code, the main command we used in Arduino it's this one:

Here I made a video showing how this command is running:

Anyways, there are other ways to run this as maybe the last one doesn't work for you, so here are other tested SOS codes for Arduino:
