In this tutorial, I am going to show you how to use the RFID Reader ID-20LA with CT-UNO (or any Arduino Uno equivalent). Before going through this tutorial, please have a look on the getting started with Compact RFID Reader, ID-20LA.
Generally, there are two methods to load the program into Arduino: USB/Serial Communication method ISP method The first method is the most common method, which implemented using USB-to-serial adapter chip/converter. For example, CT-UNO is using FTDI FT23x chips which is a
If you are building your own Arduino, or need to replace the IC, you will need to load a bootloader program into the Atmega328 (on UNO and BBFuino). There are also cases where you have put your board into a
