Tutorial: How to use Resistor 68K ohm

A 68K ohm resistor is a fundamental component for electronic projects, useful for both beginners and experts to limit currents or divide voltages.

What you need

• Arduino Uno
• Multimeter
• Wires

Steps

1. Check the resistance with the multimeter.
2. Connect the wires to the Arduino board and the resistor.
3. Use a simple sketch to measure the resistance.
4. Check the specifications on the datasheet if necessary.

Example code

int ledPin = 13; // definisci il pin collegato al LED
void setup() {
pinMode(ledPin, OUTPUT); // imposta il pin come output
}
void loop() {
digitalWrite(ledPin, HIGH); // accendi il LED
// qui inserire codice per misurare la resistenza
}

Mini project
