HI THERE ,  I would like to say Hi to everyone here ,
I"M new to this site and this is my first ever inscrutable so bare with me , 
ok so lets get started , 
first things first the lest fun reading the legal stuff , 
here it goes , I'm am NOT in anyway responsible for any injuries or harm the you my inflict on your self ,
I may and may not own this idea just in case someone had this idea first ,
please take care when handling power tools , 
ok now that I said that we can get started ,



Step 1: The Simplest Touch Switch

ok here's what you are going to need so get your pen and pad ready ,

555 timer x1 ,
dip socket for 555 timer this is optional  ,
1.5 v led any color x1 ,
pcb board or bread your choice  ,
wire 
battery 3v / 4.5 ,
a small piece of aluminum  foil ,
Tools needed 
soldering gun 
lead free solder its a better for your health if there's no lead in it
glue gun is optional 


Step 2:

ok here's a schematic I made to make it easier and also here's a pinout I got online , 
were only going to need pin 1 -2 -3-8-6 the rest we do not need ,
fallow the schematic , 
led + to 3 out 
led - to 1 ground
8  to battery 
1 ground to battery's ground
2 to touch plate 
6 to touch plate 
now to make the touch plate take a piece of foil and connect  it to the wire ,
solder your wire's to the right connections and your done ,
you can make this anyway you like solder it or use a bread board ,



Step 3:

and now the test run , touch the touch plate that was connected to pin 2 to turn on ,
to turn off touch the touch plate that was connected to pin 6 ,
so there you have it a simple touch switch , 
you can use more leds if you want or try connecting motors or what ever makes you happy  ,

Thank you everyone  for viewing my project  and for giving the new guy a chance ,
and yes I have more project to come soon ,

<p>Thanks for posting!</p><p>Do you think I could use a 12V input?</p>
Your welcome Gast&oacute;nL8 ,<br>The answer to your question is yes you can use 12v input ,<br>It goes by your 555 timers max input ,<br>Mine can handle 12v max some others can handle 16v max ,<br>I would how ever make sure your current / amps are not to high ,<br>I'v never tested mine above 2 amps before ,<br><br>Hope this help answer your question<br>Best Regards Tech savy <br><br>
how to connect this simple touch switch with arduino uno?? pliss tell me... because i want to build a safe deposit box...and i used this simple touch switch and then i connect to a solenoid to lock the deposit box...plis reply.thanks
Hi Husainjr , the best way I know would be hook pin 1 and 3 to your solenoids , <br>I'm not a 100 percent sure since I don't have arduino uno I'm planing to get one , <br>wish I could help you better but since I don't use arduino , <br>my best suggestion would be to read some of the other arduino uno users projects , <br>there's some good projects to look up I'm sure they will help you find a way, <br>if you need any other help i'll do my best to find the answers , <br>
