A More Annoying Noise Maker (Version 1.0)

Step 2 How the Circuit Works

The timer acts as a switch controlled by the resistors on pins 6, 7, and 8. The resistors basically control the pulse, timing of pulse, and even the pitch and tone of the pulses (only in audio circuits). The capacitors are basically there to control the pulsing current so it does not do any harm to other components. Once a power source is connected the timers internal circuit starts to pulse, the variable resistors control that pulse right away and that signal is sent to the speaker. So instead of having to try out multiple resistors, you only really need to do is simply turn the dial of the variable resistor and set it to the sound you like; and if you don't like it a day or two later you can change it with absolutely no solder. Just a screw driver or your fingers!
