I was inspired to make a doorbell for my bedroom just for fun and now I am posting it on instructables for the world to see.
Hope you like it! :D
To make it you need:
1 push button momentary switch
1 motor, super-bright LED, OR buzzer
1 2 AA battery clip
a sheet of paper preferably thick
a soldering iron w/ solder
1 lego plate or some other surface with large bumps
Step 1: Making the Box
I made a paper box (3 cm x 3cm x 3cm) and put a hole in the front (for the button) and one in the back (for the wires). To make the box I got a template for a cube (basicly 6 squares in a cross shape) and put my holes in and Put the momentary switch in its respective hole. next I soldered two peices of wire to the momentary switch, folded, and glued. Duct tape will work too. Using tweezers feed the wires through their respective hole.
Step 2: The Alarm-Buzzer
It should look like this:
Step 3: The Alarm-LED
REMEMBER:Do NOT solder the LED in backwards. Soldering is a measure twice, cut once sort of deal.
if you have trouble telling if your LED is backwards or not, here are 2 ways that you can tell 1-the flat spot is over the cathode, or negative end. 2- the longer wire is the annode, or the positive end. ( See picture 2 )
Step 4: The Alarm-Motor
Step 5: Conclusion
hope you liked it!
