Tutorial: How to Use a 200k Ohm Resistor

The 200k ohm resistor is a fundamental component for electronic projects, useful for both beginners and experts. It primarily serves to limit electrical currents in circuits.

What you need

• Arduino Uno
• multimeter
• 3d printer (optional)

Steps

1. Check the value of the resistor using a multimeter.
2. Connect the resistor between an input/output pin of the Arduino and ground.
3. Insert an Arduino sketch to measure the current through the resistor.

Example code

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

void loop() {
  int val = analogRead(A0);
  float voltage = val * (5.0 / 1023.0);
  float current = voltage / 200000;
  Serial.println(current);
}

Mini project

Create a light sensor using an LDR resistor and the 200k ohm resistor as a voltage divider.

Common mistakes

• Using a resistance that is too high for the circuit, excessively limiting the current.
• Connecting the resistor to the circuit without first verifying its actual value.

Recommended accessories

• Arduino Uno
• LDR
• LED
