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

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.
<p>cute red bread board. Where you get that?</p>
<p>I got it from a chinese service called taobao.</p><p>It's also on ebay for $3.44 each</p><p>http://www.ebay.com/itm/Mini-170-Tie-Points-Solderless-Breadboard-Prototype-Arduino-PIC-PI-PCB-/171435892749?pt=LH_DefaultDomain_3&amp;var=&amp;hash=item27ea60200d</p>
Thanks for the info
<p>You're Welcome</p>
<p>Can you orient your circuit diagram so it isn't a mirrored flip of what you made? Thanks for sharing!</p>
