Battery dual color light circuit

Can a bi-color led indicate two different colors?

Instead of using two different color LEDs for the indicator lamp, we can use a single Bi-color LED to indicate two different colors. Bi-Color LED Driver Circuit using a 555 timer IC. A Bi-color LED is a special type of LED that consists of two diodes that are connected in

How does a tri-colour LED circuit work?

This video shows the circuit operating. The circuit can be powered from a 9V battery but should also be able to operate over a range of voltages from 5V to 12V. The tri-colour LED used in this circuit is a three pin LED containing two LEDs in a single LED package that is capable of displaying three different colours.

What is a bi-colour LED?

A bi-colour LED is normally a two pin device that contains two LEDs. When current flows in one direction through the device, one LED switches on and the other off; when the current is reversed, the opposite LED is switched off and the other on. A two transistor circuit that flashes a tri-colour / bi-colour LED two different colours (colors).

What is the difference between tri-colour and bi-colour LEDs?

There seems to be some confusion about naming of tri-colour and bi-colour LEDs. This LED can display 3 colours and would normally be called a tri-colour LED (tri-color - American spelling), but the datasheet actually calls it a bi-polar and bi-color indicator lamp. A bi-colour LED is normally a two pin device that contains two LEDs.

What is dual color brightness adjustment?

Equipped with Dual Color brightness adjustment, this project gives you the flexibility of adjusting your light source's white balance to match your surrounding's ambient light. LED Panels are one of the essential tools for filming. Unlike softlight setups, LED panels are very versatile, portable enough to fit in your backpack.

How do you power up a red color led?

When the power is OFF, how do you power-up the RED Color LED? This circuit would be used to power up the red LED when the switch is open, then the green LED would simply be wired up to the switch. Problem is I'd need two seperate LEDs for this particular circuit to work, and what I have is a bi-color with a common cathode.
