LM556 Dual Timer IC Kit (#1500)
This is the popular LM556 Dual Timer IC Design Kit with Speakers. Includes 4 pieces of the very popular LM556 Dual Timer IC in the DIP-14 package (has leads). This great IC has two totally independent timers in one package. You can use it to build numerous timing and audio circuits. The outputs are strong enough to directly drive two different speakers!
With this kit, you also get 1/4 Watt Carbon-Film Resistors, Ceramic & Aluminum Capacitors, NPN & PNP Transistors, Potentiometers, Signal & Zener & Power Diodes, LEDs, Pushbutton Switches, Electret Microphones, a miniature Speaker, and some electronic hardware to for your I/O.
To further help you design your circuit, you also get a 162-hole Plated Thru-Hole Printed Circuit Board. The PCB was designed by us and has 4 mounting holes, is 1.1" x 2.0", is made of FR-4 epoxy-glass and is .062" thick. There are enough different parts to build many different types of Analog circuits.
