Tsukure Studio Tic Tic Sound Generator
This is a 555 timer IC based fun circuit which generates a sound of loud clicking clock. It is quite simple circuit designed by wiring the 555 IC in astable mode.
Ticking sound circuit is a good example of Astable mode of 555 timer IC. Here we are using a speaker which is used to convert electrical signal into sound. We are not using discharge PIN 7, and we have connected capacitor C2 to the OUTPUT PIN 3 of the 555 IC. Generally we used to connect the Capacitor to the voltage source, through resistors, but here we are connecting capacitor C2 directly to the OUPUT PIN 3, through a 47k ohm resistor. Capacitor will be charged through the output at PIN 3, when output PIN 3 will be HIGH. And capacitor C2 will be discharged to the Speaker when PIN 3 is LOW. When capacitor charge and discharge, speaker produce the sound of TIC-TIC.

Let's Get Building!
We to build, so let's get to it! Gather your components as specified in the components list above, or simply order one of our project packs and tip the contents out onto your table or desk.
Solder station warmed up! Snips at the ready! Here we go!
Step 1) Getting Started
Before we begin placing components and soldering we should first place your components in a small tub so that they don't roll off your table or get lost.
Lay the PCB out infront of you and take a close look at all the components we will be using.
Furher explanations and detailed specifications of all these components can be found in our Wiki.
