Tutorial: How to use USB to TTL Converter FT232RL

The USB to TTL FT232RL converter is essential for serial communication between computer and Arduino. Ideal for beginner and intermediate programmers who want to easily load sketches onto devices without an integrated USB connector.

What you need

• Arduino or device with serial port
• Computer with Windows, Mac OS, or Linux operating system

Steps

1. Connect the converter to the computer via USB
2. Check the correct installation of the driver on the FTDI website (check the datasheet for specifications)
3. Configure the Arduino IDE: set the serial port as ‘FTDI Basic’
4. Load a test sketch onto the Arduino connected to the converter
5. Verify that the converter’s indicator LED lights up during communication
6. If necessary, use a multimeter to check logic levels (3.3V or 5V) on the TX and RX pins
7. Use a software serial console such as PuTTY or Tera Term to send commands to the connected device
