Need step by step instructions for wiring a simple bread board design
I have an aftermarket GPS that has a dead reckoning feature. To use the dead reckoning feature, a speed pulse signal coming from my car is needed so the GPS can tell how fast my car is going. I had someone attach a wire to my speed pulse sensor but the voltage from the wire is around 14 - 13v and I need to drop the voltage going into the GPS to anything from 4.5 to 12v (the manufacturer says the GPS will NOT recognize anything over 12 volts. It needs 4.5 to 12.v and a 1hz to 5k hz signal).
After viewing some posts here, and visiting an electronic supply store, I purchased the following:
5.1v zener diode (stripe on one side)
1 ohm resistor (black, red stripe on one side)
Pre-stripped wires of various sizes
Breadboard
Someone suggested the following configuration:
Input--------resistor----- --output
|
|
diode
|
ground
But no one there could tell me how to put this design together. So, I have a breadboard (Elenco Bredblox Model # 9830 shown here:
http://www.tequipment.net/Elenco9830.html )
It has a single column of + on the left side, a single column of -, followed by rows titled, a,b,c,d,e (blank channel) f,g,h,i,j, and another column of + and another column -. There are two banks of 64 rows.
Can someone walk me through the breadboard design? For example, attach speed pulse wire to A2, Resistor with black red stripe on d2, other side of resister on d6, etc, jumper between a1 and d2, etc.
It seems really easy to do once you get into it, but Ive never done this type of thing before and need some assistance.
Thanks!

Hi Nobus:
Thanks for following up...I didn't get a chance to try it because I was called away for a week and only dial up internet access! I'll be back to the office tomorrow and I will give it a try then.
