To connect your Arduino Nano (U1) to the HC-SR04 ultrasonic sensor (US1), you will usually use digital pins from the Arduino for the TRIG and ECHO pins of the HC-SR04, while providing power and ground connections. Given the description of your project, here's how you can make these connections:
For power (VCC) and ground (GND) connections to the HC-SR04 (US1):
Connect US1:VCC to U1:+5V. This will power the HC-SR04 with 5V from the Arduino Nano.
Connect US1:GND to one of the U1:COM/GND pins (either pin 4 or pin 29). This establishes a common ground between the two devices.
For signal connections:
You'll need to choose two digital I/O pins on the Arduino Nano for triggering the ultrasonic pulse and reading the echo. For this example, let's use D2 and D3.
Connect US1:TRIG to U1:D2. The TRIG pin initiates the ultrasonic pulse.
Connect US1:ECHO to U1:D3. The ECHO pin receives the reflected ultrasonic pulse, allowing distance measurement.
Here are the connections in the specified format:
Connect US1:VCC to U1:+5V.
Connect US1:GND to U1:COM/GND (either pin 4 or pin 29).
Connect US1:TRIG to U1:D2.
Connect US1:ECHO to U1:D3.
Please remember, depending on your project, you might want to add resistors or capacitors for better signal integrity or to protect your pins, especially on the ECHO line. A common practice includes putting a small (e.g., 330-470Ω) resistor in series with the ECHO line and a pull-down resistor (e.g., 10kΩ) between the ECHO pin and ground.
Should any of these suggestions not fit your project needs or if you'd like a different configuration, feel free to specify, and I can adjust the recommendations accordingly.
