Electronic Traffic Light Circuits & Light Controller
The Traffic Lights circuit performs actions just like those of a real traffic light system, switching between red, amber & green.
This circuit will play a tune when light strikes a light dependent resistor, such as when a music box lid is opened.
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 adjustable over quite a range. The relay can handle up to 10 Amps at 110VAC. Oper
Preprinted Circuit Board with all the parts to assemble a controller that allows you to change directions, vary the speed, or single step the included stepper motor. Has LED's that flash when motor steps.
Three relay-based electronic switching circuits that switch according to light levels.
This kit allows you to control the speed of an AC motor. It can provide high torque at even low speeds.
This kit uses a Grey switch aka bit switch, to single step a unipolar stepper motor in either direction. Uses a
Introduces the Optocoupler-triac MOC3010. Complete electrical isolation between input audio signal (low voltage circuit) and output light modulation. Operates from 100 VAC line. Audio input via 3.5mm jack.
Use an old PC as a dedicated controller to turn on or off devices lab or radio shack. The circuit includes eight relays controlled with (included) software for either DOS or Windows 3.1. The kit is a boon to the Science Fair project, laboratory experiment
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 anything. The kit uses the MEL12 Darlington super alpha phototransistor, ty
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.

Circuits that operate just like the real gameshows, where a light shows up for the first contestant to hit their answer button.

This super cool circuit behaves as a clapper-switch. You clap and the circuit turns on. Clap and it turns off. Great as a light clap switch.
This circuit will allow you to control the level of a liquid. It switches a relay once the desired level is met.
