ATtiny85 Digispark How to Blink an LED Using Visuino

Step 1: What You Will Need

• ATtiny85 board
• Visuino program: Download Visuino

Step 2: Start Visuino, and Select the Digispark Board Type

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 "Digispark (Model A)" or "Digispark (Model B)" as shown on Picture 2

Step 3: In Visuino Add & Connect Components

• Add "Pulse Generator" component
• Connect "PulseGenerator1" pin [Out] to Digispark board > LED >Digital pin [In]

Optionally: You can set the speed of the LED blinking by selecting the "PulseGenerator1" component and in the property set the "Frequency" to a higher or lower number.

Step 4: Generate, Compile, and Upload the Project

• 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.
• Connect the board to the USB only after you click the ""Compile/Build and Upload" button" and when you see in the window a message:

"Plug in device now... (will timeout in 60 seconds)"
 "Please plug in the device ..."

• You don't need to select any port or anything else, Visuino will do all the work and Upload the project.

Step 5: Play

After uploading the project to the Digispark board the internal LED will blink.
