4 Standby light for the night
Here we will install another resistor with 330 kΩ (330 kilo-
ohms). The resistor has the color rings orange, orange, yellow
and an extra golden ring. The greater the resistance the less
current flows. Our first resistor had only 4.7 kΩ (yellow,
purple, red) and the light was relatively bright. By using the
larger resistor, the LEDs will only glow dimly.
The larger resistor used in this standby light ensures that
you can find the lamp at any time, also in the dark. When
you need to use the lamp, just turn on the higher brightness.
The same mechanism is used in some light switches. A small
glowing light helps you to find the switch easily.
