To make life easier, we also implemented a USB to Serial function to the Arduino Sketch which saves you the need of additional hardware! By default, it is defined asSerial1and it's the Hardware Serial pins. For example, it's pin 6 and 7 for Seeeduino XIAO. ...

but the USB to serial TTL converter I ordered from Ebay still hadn’t arrived. So I got all these cool bluetooth 4.0 and Wi-Fi modules I couldn’t use, or so I thought at first. In this tutorial I’ll show you how to use an Arduino as a bridge between your computer and Serial ...
