Features

• Measures DC voltage up to 100V
• Measures DC current up to 10A
• Includes red LED to indicate current

What it is for

This voltmeter and ammeter is ideal for monitoring voltage and current levels in electronic prototypes. It can be used to create energy consumption monitoring systems, displaying real-time voltage and current values.

Tutorial: How to use DC 100V 10A Voltmeter with Red LED

This digital voltmeter and ammeter is ideal for monitoring voltage and current levels in electronic circuits. It is perfect for both beginners and experts, offering a clear and precise reading.

What you need

• Arduino Uno
• USB A-Micro B Cable
• Protoboard Connections
• Battery or External Power Supply

Steps

1. Connect the voltmeter to the circuit between the power source and the element you want to monitor.
2. Connect the Vcc, GND, COM and AMP pins of the voltmeter to the power supply and desired current signals.
3. If necessary, connect the voltmeter to an Arduino for digital reading of voltage and current values.
4. Install the required software on the Arduino (see code below).
5. Check that the red and blue LEDs light up in response to current levels.
6. Adjust the switch to select voltage or amperage mode.
7. Monitor the digital display for current and voltage readings.

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
  int val = analogRead(A0); // Leggi dal voltmetro collegato ad A0
  float voltage = (val / 1024.0) * 5;
  Serial.println(voltage);
}

Mini project
