Code Examples

Example 1: Basic Measurement using Arduino

In this example, we will use the Mastech MS8217 to measure the voltage of a 9V battery and display it on an Arduino Serial Monitor.

Hardware Requirements:

Mastech MS8217 Digital Multimeter Meter
 Arduino Board (e.g., Arduino Uno)
 Breadboard and jumper wires

Software Requirements:

Arduino IDE (version 1.8.x or later)

Code:
```cpp
const int multimeterPin = A0; // Connect the multimeter's voltage output to Arduino's analog input A0

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

void loop() {
  int reading = analogRead(multimeterPin);
  float voltage = reading  (5.0 / 1023.0); // Convert analog reading to voltage (assuming 5V reference)
  Serial.print("Voltage: ");
  Serial.print(voltage);
  Serial.println(" V");
  delay(1000);
}
```
Example 2: Interfacing with Raspberry Pi for Automation

In this example, we will use the Mastech MS8217 to measure the current flowing through a load connected to a Raspberry Pi's GPIO pins.

Hardware Requirements:

Mastech MS8217 Digital Multimeter Meter
 Raspberry Pi (e.g., Raspberry Pi 4)
 Breadboard and jumper wires
 Load (e.g., LED, resistor)

Software Requirements:

Raspbian OS (latest version)
 Python 3.x

Code:
```python
import RPi.GPIO as GPIO
import time

# Set up GPIO pins for output
GPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)  # Load connected to GPIO 17

# Set up multimeter on GPIO 18 (analog input)
multimeter_pin = 18

while True:
    # Measure current using the multimeter
    current_reading = GPIO.input(multimeter_pin)
    current_amps = current_reading  (5.0 / 1023.0) / 100  # Convert analog reading to current (assuming 5V reference and 100mA full scale)

# Control the load based on the measured current
    if current_amps > 50:
        GPIO.output(17, GPIO.HIGH)  # Turn on the load if current exceeds 50mA
    else:
        GPIO.output(17, GPIO.LOW)  # Turn off the load if current is below 50mA

time.sleep(1)  # Take readings every second
```
