Tutorial: How to use 1.2M ohm Resistor

The 1.2M ohm resistor is a fundamental component to limit the flow of current in electronic circuits. Ideal for beginners and intermediate projects that require a high resistance.

What you need

• Arduino Uno
• Resistance Reader
• Jumper Wire

Steps

1. Check the resistance with a resistance reader.
2. Connect one end of the Arduino to GND and the other end to pin A0 using jumper wires.
3. Write an Arduino sketch to read the value of the analog pin A0.
4. Verify the read values on the Arduino serial monitor.

Example code

const int analogPin = A0;

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

void loop() {
  int sensorValue = analogRead(analogPin);
  float voltage = (sensorValue / 1024.0) * 5.0;
  Serial.println(voltage);
}

Mini project

Create a simple thermometer by connecting a thermistor to this resistor and reading temperature changes with Arduino.

Common mistakes

• Connect the resistor to a digital pin instead of an analog pin
• Use it in series with direct power supply without a current limiting circuit
• Do not check the resistance value before use

Recommended accessories

• Arduino Uno R3
• Various colored jumper wires
• Resistance reader
• 10k ohm resistors for pull-up/down

Frequently asked questions

How do you read the resistance value?
