25 Flickering and flashing with six LEDs
With a total of six LEDs and two identical resistors of 1k Ω
(brown, black, red), we are going to create a colourful and
varied LED light at the end, in which all LEDs flash or flicker.
Actually, the package contains only two LEDs with a built-in
controller. But there are some circuit tricks with which other
LEDs can blink or flicker.
The circuit consists of two LED series circuits and a bridge
circuit with two oppositely poled LEDs. Note the installation
direction of each LED. If something does not work, it could be
because an LED was installed the wrong way around.
