Hardware connections:
Uno Pin INA169 Board Function
+5V VCC Power supply
GND GND Ground
A0 VOUT Analog voltage measurement
VIN+ and VIN- need to be connected inline with the positive
DC power rail of a load (e.g. an Arduino, an LED, etc.).
*/
// Constants
const int SENSOR_PIN = A0; // Input pin for measuring Vout
const int RS = 10; // Shunt resistor value (in ohms)
const int VOLTAGE_REF = 5; // Reference voltage for analog read
// Global Variables
float sensorValue; // Variable to store value from analog read
float current; // Calculated current value
void setup() {
// Initialize serial monitor
Serial.begin(9600);
}
void loop() {
// Read a value from the INA169 board
sensorValue = analogRead(SENSOR_PIN);
// Remap the ADC value into a voltage number (5V reference)
sensorValue = (sensorValue * VOLTAGE_REF) / 1023;
// Follow the equation given by the INA169 datasheet to
// determine the current flowing through RS. Assume RL = 10k
// Is = (Vout x 1k) / (RS x RL)
current = sensorValue / (10 * RS);
// Output value (in amps) to the serial monitor to 3 decimal
// places
Serial.print(current, 3);
Serial.println(" A");
// Delay program for a few milliseconds
delay(500);
