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 "Arduino UNO" as shown on Picture 2

1 / 3

• Add "Clock Generator" component
• Add "MAX6675" component
• Add "TM1637 7 Segment Display 4 Digits Module + 2 Vertical Points (CATALEX)" component
• Select "Display1" and in the properties window set "Points" to True
• Double click on the "Display1" and in the "Digits" window Drag "Analog Display 7 Segments" to the left side
• Close the "Digits" window

1 / 3

• Connect "ClockGenerator1" pin [Out] to "Thermometer1" pin [Clock]
• Connect "Thermometer1" pin [Out] to "Display1" pin [In]
• Connect "Thermometer1" pin Control [SPI] to "Arduino" pin SPI [In]
• Connect "Thermometer1" pin Control [Chip Select] to "Arduino" digital pin [10]
• Connect "Display1" pin Control [Clock] to "Arduino" digital pin [8]
• Connect "Display1" pin Control [Data] to "Arduino" digital pin [9]

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.

If you power the Arduino module, The LED Display will show the Temperature from the MAX6675 sensor.
