Tutorial: How to use MAX471

The MAX471 is a module for measuring current and voltage, ideal for electric monitoring projects.

What you need

• MAX471
• Arduino
• Power cable
• Multimeter

Steps

1. Check the MAX471 datasheet specifications.
2. Connect VCC to 5V Arduino.
3. Connect GND to GND Arduino.
4. Connect the OUT pin to the A0 pin of Arduino to read the voltage.
5. Connect the IOUT pin to the A1 pin of Arduino to read the current.
6. Load the Arduino code.
7. Check the measurements with the multimeter.
8. Select a current or voltage monitoring project.

Example code

```void loop() {  int tensione = analogRead(A0);  int corrente = analogRead(A1);  Serial.print("Tensione: ");  Serial.println(tensione);  Serial.print("Corrente: ");  Serial.println(corrente);  delay(1000);}

Mini project

Build a current monitor for a test circuit in 30 minutes.

Common mistakes

• Connect VCC to 3.3V instead of 5V.
• Forget to check the specifications on the datasheet.
• Do not use a multimeter to check the measurements.
• Connect the output pins to the digital pin instead of the analog pin.
