Breadboard (prototyping board) – The basics

A breadboard or prototyping board, is a little board made of plastic studded with little holes where we can connect a lot of electronic components. What’s the point ? It’s about multiplying the pins of your Arduino/Raspberry Pi or every other device working with pins. If you don’t understand quite well, let’s take a concrete example : We want to set up a system which will retrieve the temperature from different temperature probes. We have

Serial – The basics

The Serial is the default communication protocol of Arduino. This means its via Serial that data transmits. For example, when you upload your code to your Arduino, it is via Serial (with a USB cable). You can check data transmission in real-time with TX and RX LEDs. TX blinking => Arduino is transmitting data. RX blinking => Arduino is receiving data. You can try to upload your code to the Arduino and watch for the RX led
