• Ultrasonic Sensor HC-SR04
• Arduino UNO R4
• Jumper wires
• Visuino program: Download Visuino

• Connect Ultrasonic module pin (VCC) to Arduino pin [+5V]
• Connect Ultrasonic module pin (GND) to Arduino pin [GND]
• Connect Ultrasonic module pin (ECHO) to Arduino pin digital (2)
• Connect Ultrasonic module pin (TRIG) to Arduino pin digital (3)

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 R4 WiFi" as shown on Picture 2

• Connect "UltrasonicRanger1" pin [Out] "AnalogToInteger1" pin [In]
• Connect "AnalogToInteger1" pin [Out] to "MultiSource1" pin [In]
• Connect "MultiSource1" pin [0] to ArduinoUNO R4 WiFi > Display > "Fill Screen1" pin [clock]
• Connect "MultiSource1" pin [1] to ArduinoUNO R4 WiFi > Display > "Draw Text1" pin [Text]
• Connect "MultiSource1" pin [1] to ArduinoUNO R4 WiFi > Display > "Draw Text1" pin [clock]

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 LEDs on the Arduino Display will start to indicate the distance of the obstacle detected by ultrasonic sensor.

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.com
