50 Pack 1.5 Ohm 1/4W Resistor 5%

Description

50PCS 1.5 ohm resistor 1/4w 1/4 w 5%

Tutorial: How to use 1.5 ohm resistor

The 1.5 ohm resistor is a fundamental component for electronic projects, used to limit the flow of current in circuits such as those for Arduino or 3D printing. Ideal for beginners and intermediate makers.

What you need

• Arduino Uno
• Multimeter
• Jumper wire

Steps

1. Check the resistance with a multimeter.
2. Connect the red lead of the jumper wire to the resistor.
3. Connect the black lead of the jumper wire to the other end of the resistor.
4. Connect the free ends of the jumper wires to two pins of Arduino (e.g., GND and 5V).
5. Use a multimeter to measure the voltage between the two pins connected to the resistor.
6. Verify that the resistance value is in accordance with the nominal value (1.5 ohm) using Ohm’s equation (U = R * I).

Mini project

Create a simple circuit to measure the current through an LED lamp with the support of a 1.5 ohm resistor.

Common mistakes

• Do not check the resistance value before use.
• Incorrect polarity connection of the resistor.
• Use of excessive voltage that exceeds the maximum power (1/4W).
• Imprecise calculation of the current flow through the resistor.

Recommended accessories

• Arduino Uno R3
• Jumper cable kit
• Digital multimeter
