Hey guys new to this forum and new to electronics. I have tinkered with 555 timers for flashing, counting, etc a little but thats about the extent of my knowledge so i am trying to get some expert help here. I am a complete noob so please be civil with me i am going to have a lot of stupid questions.
I am on a project to make a gear indicator circuit for my motorcycle so when i shift the gear up or down it will correctly tell me what gear I am in. Before anyone jumps to conclusions, yes its possible and there was a guy years ago that had a friend build a circuit (which i have the schematics to) that does just this along with instructions on how to modify the neutral sensor indicator to my motorcycle.
Now i have attempted to contact both of the guys that completed this project years ago but they are no longer part of the forums or no longer log in so this is the reason i am here.
First here is the website of the instructions for modification.
Mr. Clean & Ace280's Gear Indicator
There is a schematic at the very end of the page that i am working with along with a list of parts. I will post these below.;
Now i have already ordered and received all the parts listed in the gear parts list.txt attached to this post.
The issue i am having is making heads or tails of the schematic.
So here are my questions:
1. Everything listed as VCC, what IC should that connect to?
2. What do P1-P8 mean and connect to?
3. Should pin 11 be connected to anything or left unconnected?
4. Should there be a 12v power source on this circuit anywhere or will the power supplied come from the gear shift sensor?
I know that P9-P15 are the outputs for to the 7-seg LED display and the P16 is most likely the ground for the display so that i have figured out.
I have breaded this circuit the best i could figure out and i cant seem to get it working. I can get the display to read 0 and 7 and even that is sporadic at best.
A noob stupid re diagram using an icon of the IC rather than the gates and inverters like this one had would be much more helpful if anyone can read this.
Can anyone please help me with this?
