LED (5 mm) Basic Circuit

Build a basic LED (5 mm) circuit with labeled pins, component values and connection guidance.

LED (5 mm) in a circuit

Supply, series resistor, LED and the return to ground.

5 V supply through a 220 ohm resistor into the LED anode, cathode to ground; current about 14.3 mA for red and 7.7 mA for blue.
The resistor can sit on either side of the LED; the current is the same.

Connect it, step by step

Follow the component values and pin connections

Choose the current

10–20 mA for a bright indicator, a few mA for a panel light.

Size the resistor

R = (5 V − Vf) / I; take the next E24 value above.

Mind the polarity

Long lead to the resistor side, short lead and flat to ground.
