Tutorial: How to use 0.680 ohm Resistor

Resistors are fundamental components to limit the flow of electrical current in a circuit. This 0.680 ohm resistor is ideal for Arduino projects, 3D printing or any other project that requires a low value resistor.

What you need

• Arduino Uno
• Jumper Wire
• Multimeter

Steps

1. Check the resistance value using a multimeter in ohm mode.
2. Connect the resistor between two Arduino pins. For example, connect one end to GND and the other to one of the input/output pins.
3. Use the Arduino sketch to measure the value of the resistance with a digital multimeter or read the value of the circuit.
4. Check that the resistance does not exceed the power limits (1/4 watt) during use.

Mini project

Create a simple project to measure the electrical current through a resistance using Arduino. Connect the resistance to one of the input/output pins of the Arduino, write the sketch to read the value of the resistance.

Common mistakes

• Using a resistance with a value too low that can cause circuit overload.
• Not verifying the maximum power of the resistance before using it in a project.

Recommended accessories

• Arduino Uno
• Basic Kit for Arduino
• Multicolored jumper wire

Frequently asked questions

How do you read the value of a resistance?
Use a multimeter in ohm mode and connect the terminals of the resistance to the two pins of the multimeter.

What is the difference between 1/4 watt and 1 watt?
The power rating of a resistor indicates how much heat it can dissipate before it gets damaged. A 1/4 watt resistor can handle less heat than a 1 watt resistor.
