Touch: Light Control
Photo Sensor with Control Relay
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
Traffic Lights Kit / Circuit
The Traffic Lights circuit performs actions just like those of a real traffic light system, switching between red, amber & green.

This is a RC car project is the transmitter and receiver modules for a Remote Control car, with speed control and continuous steering.
Touch Switch Relay Board
Both a touch and a contact switch are built on one PC board so that the builder can see how each works. A battery can power the contact switch but you'll need an AC power supply for the touch switch to work well. The circuit switches a relay with a 3 Amp
InfraRed Remote Control Switch - Infared Remote Control
Power on/off almost anything with this infrared controlled electronic switch. Some spell it Infared!
Light Activated Music Box
This circuit will play a tune when light strikes a light dependent resistor, such as when a music box lid is opened.
Light Activated Relay Switches
Three relay-based electronic switching circuits that switch according to light levels.
Stereo Pre-Amplifier with Tone Control
This stereo pre-amplifier will allow you to get extra control over your audio.
Sound Activated Electronic Switch
Adjust the sensitivity of this circuit to control a Relay that can turn on whatever is connected to the contacts of the relay. Very practical circuit for a variety of projects. Turn on a light when your dog barks, or set of a siren when an intruder makes
