Vibrational frequency detector circuit

Post by 7seven777 »

I followed the diagram to build the vibrational frequency detector circuit that was in your "Measuring Vibrational Frequency with Light project."
I used the second schematic diagram in it.

However, the circuit i built does not function properly.
This link has a picture of the circuit i made using the diagram https://mail.google.com/mail/u/0/?ui=2& ... sp=safe&zw

Could you send me an actual picture of how the vibrational frequency detector circuit is supposed to look like when its on a solderless breadboard.
If you do have a picture of the complete circuit send it to my email which is [MODERATOR REMOVED].
If you cant send me a picture, then send me something that can tell me how to make the circuit properly on a breadboard.

7seven777,

Welcome and thank you for your post. First, it is Science Buddies policy not to post personally identifying information or to communicate directly via email. This is for both your safety and ours. For this reason, your email address has been removed.
Second, pictures can be uploaded and posted to this forum and that is how the SB experts will communicate.
Hope this helps.
