In this Tutorial we will learn how to use Seeeduino XIAO by making a Simple LED Blink project.

Watch the video!

Step 1: What You Will Need

Seeeduino XIAO
LED
1K ohm resistor
Breadboard
Jumper Wires
Visuino program: Download Visuino

Step 2: About Seeeduino XIAO

Powerful CPU: ARM® Cortex®-M0+ 32bit 48MHz microcontroller(SAMD21G18) with 256KB Flash,32KB SRAM
Flexible compatibility: Compatible with Visuino & Arduino IDE
Easy project operation: Breadboard-friendly
Small size: As small as a thumb(20x17.5mm) for wearable devices and small projects.
Multiple development interfaces: 11 digital/analog pins, 10 PWM Pins, 1 DAC output, 1 SWD Bonding pad interface, 1 I2C interface, 1 UART interface, 1 SPI interface.

Typical Application

Wearable devices
Rapid prototyping (directly attached to the expanded PCB as a minimal system)Perfect for all the projects need mini Arduino
DIY keyboard
USB development (USB to multi-channel TTL/USB host mode, etc.)
A scenario where you need to read multiple mock values The DAC output

Step 3: The Circuit

Connect XIAO board pin [GND] to LED negative pin [-]
Connect XIAO board pin [7] to 1k ohm resistor
Connect 1k ohm resistor second pin to LED positive pin [+]

Step 4: Start Visuino, and Select the Seeeduino XIAO Board Type

The Visuino: https://www.visuino.eu also needs to be installed. Download Free version or register for a Free Trial.

Start Visuino as shown in the first picture Click on the "Tools" button on the Arduino component (Picture 1) in Visuino When the dialog appears, select "Seeeduino XIAO" as shown on Picture 2

Step 5: In Visuino Add,Set & Connect Components

On the right side of Visuino type "Pulse Generator" in the search box and drag the component to the main Area (Picture1)
Connect "PulseGenerator1" component Pin [Out] to "Seeeduino XIAO" Digital Pin [7] (Picture 2 and Picture 3)

Step 6: Generate, Compile, and Upload the Arduino Code

In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.

Step 7: Play

If you power the Seeeduino XIAO module, the LED will start to blink.

Congratulations! You have completed your project with Visuino. Also attached is the Visuino project, that I created for this Tutorial, you can download it and open it in Visuino: https://www.visuino.eu
