Hello everyone. New to the site, seems very informative and helpful. I am also new to electronics.
I’m hoping you guys can help me out. I am building a counter circuit based off the Icm7225 triggered from an optical sensor such as a photomicrosensor from omron or other optical sensor. This is going to count how many rotations a shaft turns, basically a unit counter.
The data sheet say it counts with every negative transition. Does it mean it uses a neg. voltage -5v instead of a pos. voltage +5v ?
I plan on using something like this for a sensor.
would this sensor work? would it directly connect with the chip?
oh this sensor is a NPN should I use a PNP?
If possible would someone please draw a schematic showing how to make this counter? if drawing it is to big of a hassle I understand.
Thank you in advance, lots of questions I know.
I did search this forum but did not find the answer.
If anybody has questions about building computers or computer related questions please feel free to ask. hopefully I can help
