Tutorial: How to Use Digital Voltmeter and Ammeter YB4835VA

The Digital Voltmeter and Ammeter YB4835VA is useful for monitoring voltage and current in electronic circuits. Ideal for beginner and intermediate makers.

What you need

• Digital Voltmeter and Ammeter YB4835VA
• Arduino or compatible microcontroller
• Power cable
• Resistor (optional)

Steps

1. 1. Check the product specifications in the datasheet.
2. 2. Connect the power supply cable to the VCC and GND terminals.
3. 3. Connect the microcontroller to the VCC and GND terminals.
4. 4. Connect the A0 terminals to pin A0 of the microcontroller.
5. 5. If necessary, add a resistor between A0 and GND to protect the microcontroller.
6. 6. Load the Arduino code.
7. 7. Enter the voltage and current values in the code.
8. 8. Run the code and check the values on the display.

Example code

void loop() {
  float tensione = analogRead(A0) * (5.0 / 1024.0);
  float corrente = tensione / 0.1; // Assumendo resistenza di 0.1 ohm
  Serial.println(tensione);
  Serial.println(corrente);
}

Mini project

Build a simple power supply circuit with a load and monitor voltage and current.

Common mistakes

• Do not connect the microcontroller directly to the A0 terminals without a resistor.
• Ensure that the maximum voltage does not exceed 5V.
• Check that the maximum current does not exceed the microcontroller’s capacity.
• Make sure the display works correctly before connecting to the microcontroller.
