Lesson 7: On / Off Touch Switch with Transistors


               7.1 Overview

               In this lesson we are going to make a switch using two touch probes one is ON and the other
               one is OFF.


               7.2 Components Required

               1 x Breadboard Power Supply
               1 x 9V Battery
               1 x 9V Battery Connector
               1 x Breadboard 830p
               1 x 2N2907 PNP Transistor
               3 x 2N2222 NPN Transistor
               1 x 5mm red LED
               1 x 220 Ω resistor
               1 x 100 KΩ resistor
               1 x 10 KΩ resistor
