Lights & Light Control

Items in this category perform functions involving light. Most of the circuits here work with LED's (Light Emitting Diodes).
Flashes five very bright LED's in any one of seven, user-selectable, patterns. A COB (chip-on-board) IC makes assembly very easy; the chip is supplied premounted on its own board a...
A sensitive photo Darlington transistor is used with a CMOS nand gate. The circuit detects light and triggers a siren. You could add your own triac or relay and switch practically ...
Versatile light organ based on PIC microcontroller.
The most popular use for this kit is to make you own night-light. It can also be used to switch just about any appliance on or off in light or darkness. Light sensitivity is adjust...
The circuit flashes five LED's in sequence repeatedly until you turn it off. Flash rate is user adjustable. The circuit uses an IC chip on Board which you will then mount on the in...
This is a very eye appealing audio accessory. Displays an approximate output level for each channel of a stereo amplifier. Connects to the speaker terminal; levels are displayed in...
The Traffic Lights circuit performs actions just like those of a real traffic light system, switching between red, amber & green.
A bright, variable flash rate strobe light. This is a 9 Volt battery powered xenon tube flasher. A small circut is easily transported for camping etc. Flash rate may be varied betw...
