Hello,
I need help to create a simple circuit to amplify a small signal of 300mv to 5v so I can read it from the Arduino.
The signal comes from a camera hotshoe. Everytime the camera takes a picture, this signal goes from 0v to about 300mv, and back to 0v after the picture has been taken.
I tried using this board, https://www.amazon.com/LM-YN-Millivolt-Amplifier-Instrumentation/dp/B01MRJKY2V to amplify my signal. It did not seem to work at all i.e. output voltage is always at 4.8v. Could you suggest a simple circuit?
Thank you so much for your help.
