Introduction: The Beeper

Picture of The Beeper

A little device that constantly beeps.

Step 1: Explenation

If you turn the pointiometer (Variable Resistor) the beeping will go faster/slower.

Step 2: Materials

Picture of Materials

1. 555 timer chip
2. 220r resistor
3. 50k variable resistor
4. 36uf capacitor
5. 5v piezo beeper
6. breadboard

Step 3: Hook Up

Now you just build the circuit from the (messy) diagram.

Step 4: Finish

Now just power it and it should start beeping.

I got it from a chinese service called taobao.

It's also on ebay for $3.44 each

Can you orient your circuit diagram so it isn't a mirrored flip of what you made? Thanks for sharing!
