Science Buddies: "Ask an Expert"

Hello , I am currently trying to perform the procedure for this experiment: Measuring Vibrational Frequency with Light
https://www.sciencebuddies.org/science- ... p015.shtml

I am very short on time and can't get the first part done. I am not sure how to create the circuit, so if anyone can explain that in detail with the exact places on the solderless breadbord to put the coverter/ resistor and everything else on how to make the circuit please reply quick. I DON'T HAVE MUCH TIME!!!!!!

Hello ScienceGuy1.

The following drawing should help you to assemble the Vibration Frequency Detector Circuit on a small breadboard.

Please let us know if this has helped you with your project.

Good Luck!

Hello again ScienceGuy1.

I appologize for the drawing not turning out correctly.

I Have had this problem before.

I try to draw pictures using the old school Mainframe style of drawing very limited pictures.

Anyhow, if I can help you just Post the specific question and I will try and get you the answers,


Good Luck with your project!
