CuteDuino USB Tutorial

Recently Cytron have launch a new product called CuteDuino (RM25 only!). If you are new to this product, please read the CuteDuino User’s Manual first. For quick start guide video, please refer to this link. Since CuteDuino don’t have serial COM port (like Arduino Uno) or virtual COM port (like Arduino Leonardo) to act as monitor, this tutorial will guide you how to use USB as a monitor and control.


1. CuteDuino (link).
2. USB Micro B Cable (link).

Modified Arduino IDE (by Digispark) and DigiUSB Programs.

Before we proceed to USB driver installation, we need to program the CuteDuino with USB function.
*All this step have been record on the video
1. Connect USB Micro B cable to CuteDuino.
2. Open Arduino IDE and type this example code to the new sketch. Upload to the CuteDuino.

[code lang=”c” highlight=””]
#include <DigiUSB.h>

#define led 1 // LED on CuteDuino connected to pin1

char inByte = 0;

void setup()
pinMode(led, OUTPUT); // Set LED on CuteDuino as output
DigiUSB.begin(); // USB begin
DigiUSB.println(“USB ready”); // USB print

void loop()
if(DigiUSB.available()) // Incoming data from USB
inByte =; // Read incoming data from USB
if(inByte == ‘0’) // If data equal to ‘0’
digitalWrite(led, LOW); // Turn OFF LED
DigiUSB.println(“LED OFF”); // Print status to USB
else if(inByte == ‘1’) // If data equal to ‘1’
digitalWrite(led, HIGH); // Turn ON LED
DigiUSB.println(“LED ON”); // Print status to USB
DigiUSB.delay(10); // Refresh the usb port for 10ms

3. Go to DigiUSB Programs – DigiUSB Windows Driver and install “InstallDriver.exe“. Done Installation
4. Open Device Manager, and look for libusb-win32 Usb Devices – DigiUSB. USB driver installation is succeed.
5. Go to DigiUSB Programs and open digiusb.exe.
6. Type 1 (followed by enter) to turn ON the LED and Type 0 (followed by enter) to turn OFF the LED.

* If you are having problem with program loading, please check pin 3 and pin 4. Try avoid using it during program loading as it is shared with the USB pins.

  1. How to upload the code? The code that you give here did not declare what is DigiUsb and errors were display. I still don’t understand how it is work.

  2. hi,

    for the first line of the program it states:


    should there be something after the #include like iostream, usb…? is there something missing or is it just me?
