Infrared: Sensor Led

A circuit with 8 LEDs that flash in a somewhat random fashion (well it's not actually at random, but it does visually appear that way).

Circuit diagram for an ultra low-noise driver/supply circuit for white LEDs, using the IC LTC3201. Ensures a stable brightness in white LED driven items.

This super sensor detector sounds an alarm if someone approaches the unit. Adds safety to your home or office. Learn the basics of motion detector technology. Uses pyroelectric infrared sensor.

This kit uses an infrared beam to monitor door & passage-ways or any other area.

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 included mother board; battery holder is included. Powered by a 3 volt supply

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 and a motherboard contains the entire circuit. Operates on 3 volts DC, batte

Versatile light organ based on PIC microcontroller.

Electronic circuit schematic that works as a Hangman LED game. Fun game to play with a friend, and very educational and entertaining circuit to build.

Schematic for an electronic circuit that behaves as an electronic version of a Roulette wheel. Flashed 10 LEDs in sequence with slowing pace until only 1 remains illuminated.

Schematic for an electronic audio level VU meter that uses LED's to display the volume/audio levels.

Similar to lail couriers used in large corporations, the Line Tracker follows a designed course. By using an infrared emitter and light-sensor circuitry, it demonstrates how robots "see" a pathway. Make a pathway with a black felt marker or blac

Low cost 12 channel Infrared Remote Control with relay board

A simple circuit that flashes an LED when a cell phone has an incoming call. Uses a coil to pick-up the signal emitted during an incoming call event. Cell phone call detector.

A bit different from other kits. We supply the three basic components for you to make your own movement detector. Included is a PCB mounted fresnel lens, a PIR movement sensor and the latest movement IC just released. Eight pages of application notes show

A stronger, Mecha-Medusa is a walking robot that operates with the aid of a sound sensor. Clap hands or snap fingers to command this robot to start walking on four legs. Stops automatically after a preset time. Ideal for the hobbyist or budding scientist.

Power on/off almost anything with this infrared controlled electronic switch. Some spell it Infared!
