Circuit Components — buying guide

What is in this category

4 products: 10k potentiometer, Push Button, Resistor (THT, 1/4W, Carbon), 5mm LED.

How to choose

  • A 220–330 Ω resistor in series is a must when connecting an LED to an Arduino pin.
  • Learning analog input → 10k potentiometer (to pin A0).
  • Buttons → push button + 10k pull-down resistor (or INPUT_PULLUP).

Compatibility

Everything plugs straight into a 2.54 mm breadboard; works in 3.3V and 5V circuits.
