The INA333 is a triple operational amplifier ideal for measuring low-amplitude signals. Useful for beginner and intermediate makers.

What you need

• Arduino or compatible microcontroller
• Test lead
• Digital multimeter
• 10kΩ resistor (for testing)

Steps

1. 1. Connect the INA333 to the microcontroller using the following pins: VCC to 5V, GND to GND, SDA to SDA, and SCL to SCL.
2. 2. Connect an input signal to one of the input channels.
3. 3. Check the datasheet to properly configure the I2C registers.
4. 4. Load the provided Arduino code.
5. 5. Check the output with a multimeter.
6. 6. Repeat for the three input channels.
7. 7. Verify the system stability.
8. 8. Adjust the amplification coefficients if necessary.

Example code

```void setup() {  Wire.begin();  // Inizializza I2C}void loop() {  Wire.beginTransmission(0x48);  Wire.write(0x00);  Wire.write(0x00);  Wire.endTransmission();  delay(1000);  Serial.println(Wire.read());}```
