Resistor 470 Ω (1/4W)

Resistor

Carbon film resistor. One of the most common values for limiting an LED's current: about 10 mA through a red LED on 5V, so both the LED and the Arduino pin stay safe.

Projects with this part

• LED BlinkBeginner10 minYour first project: it blinks an LED on the Arduino's pin 13 once a second and writes each change to the Serial Monitor. It teaches you to use a breadboard, an LED and a resistor. The board's own L light is also on pin 13, so it blinks along with the LED. No extra library needed.Open project
• Arduino-Free Dark-Activated LampBeginner25 minA night light with no Arduino and no code, built from just a 9V battery, a BC547 transistor, an LDR and a potentiometer: when it gets dark the LED lights by itself, and it goes out when the light comes back. With the potentiometer you set how dark it must be. It teaches three cornerstones of basic electronics: the voltage divider (the potentiometer and the LDR), the transistor as a switch that turns a large current on and off with a small base current, and limiting an LED's current with a resistor. You see how these parts, used in Arduino projects all the time, work without one.Open project
