Tutorial: How to use 6.8K ohm Resistor

The 6.8kΩ resistor is a fundamental component for electronic projects, useful for limiting current flow in circuits such as those used with Arduino.

What you need

• Arduino Uno
• Connectors
• Needle Nose Pliers

Steps

1. Install the resistor on a breadboard.
2. Connect one end of the resistor to a digital pin on the Arduino.
3. Connect the other end to ground (GND) or another component such as an LED.
4. Check the circuit operation with Arduino IDE.

Example code

void setup() { pinMode(13, OUTPUT); }
void loop() { digitalWrite(13, HIGH); delay(500); digitalWrite(13, LOW); delay(500); }

Mini project

Create a simple dimmer for an LED using the 6.8kΩ resistor as part of the current limiting circuit.

Common mistakes

• Connect the wrong end of the resistor.
• Do not verify the resistor values with a multimeter.
• Use a resistor that is too small or too large for your application.

Recommended accessories

• Arduino Uno
• LEDs in various colors
• Breadboard
• Test Connections

Frequently asked questions

How can I verify the value of a resistor?
Use a multimeter and measure the value between the terminals of the resistor.

What is the difference between a 6.8kΩ resistor and a 10kΩ resistor?
The resistance value determines how much it limits the flow of current in the circuit; a higher resistance impedes a greater flow.
