Page 4 - SUMMARY OF THE PROJECTS

PROJECT 1: THE HIGH GAIN AMPLIFIER

This project shows how two transistors can be used to turn ON a Light Emitting Diode (LED) from a touch plate. The amplifier has a gain of more than 10,000. It is our High Gain Amplifier building block.

PROJECT 2: THE LED FLASHER

A two transistor circuit is used to flash a Light Emitting Diode

• The touch plate is used to change the flash rate.
• A fixed resistor is used to set the flash rate to 2Hz (2 flashes per second).

PROJECT 3: THE FLIP FLOP

A Flip-Flop circuit is constructed on the Printed Circuit board to alternately flash two Light Emitting Diodes(LEDs). This is our Flip Flop building block.

PROJECT 4: FIBRE OPTICS

Create your own flashing fibre optic sign using the LED Flasher circuit and a 7x10 (holes) matrix board to produce a wide variety of signs and shapes using the plastic optical-fibre included.

PROJECT 5: SIMPLE SIREN

A Simple Siren circuit is constructed on the Printed circuit board and the touch plate is used to raise and lower the tone. This is our oscillator building block. This project can be used to detect water (such as rain) on the touch plate or water level such as in a bath or tank or the flooding of a cellar.
