This blinking light circuit is a basic circuit that is suitable for those who are interested in learning electronics related to IC No.555, both LED sets will turn on and off alternately, which the user can adjust the speed of blinking.

This circuit is a small light circuit The operation of the circuit will work automatically when it gets dark. Suitable for installation in energy-saving house model or point Tell locations such as light switches or outlets, etc.

This flashing light circuit is a basic circuit that is suitable for those who are interested in learning about electronics related to IC op-amps. The LED can choose to work by turning on and off alternately or LED brightness adjustment circuit (DIMMER)

Circuit is suitable for learning about op-amp ICs The running style will run from the first to the last and then turn off or set to turn off completely. When the light has reached the last light or it can be flashing and turning off.

A basic circuit that is suitable for those who are interested in learning and knowledge of electronics related to multi-purpose ICs that are commonly used No.555, both LEDs will turn on and off alternately, which the user can adjust the speed of blinking.

This is an easy game-play electronic version of the traditional coin-flip decision maker. Just cover the sensor on the FK193, both LEDs will alternately flash. When remove the cover, the LED action will slow down until randomly one LED remains lit.

3 Volt DC 100ma Power Supply for use with FK200 Series 3 volt Kits.

Triple Welder Kit with selectable pauses. 3 super bright welder flash LEDs in one kit. Micro processor controlled special effects. Great for multiple welders in one scene or across the layout. see details

Two LED hearts are pierced by an arrow.

LEDs in this flasher kit are aligned in the shape of a robot. This is a fun and easy circuit to assemble for beginners!
