The MCP6004 can be used to amplify an analog signal for an Arduino UNO's ADC. Below is an example circuit and code:
// MCP6004 Example: Reading an amplified signal from Op-Amp A
const int analogPin = A0; // Analog pin connected to OUT A of MCP6004
void setup() {
Serial.begin(9600); // Initialize serial communication
}
void loop() {
int sensorValue = analogRead(analogPin); // Read the amplified signal
float voltage = sensorValue * (5.0 / 1023.0); // Convert ADC value to voltage
// Print the voltage to the Serial Monitor
Serial.print("Amplified Signal Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(500); // Wait for 500ms before the next reading
}
