I hosted a webinar on November 10, 2023 on

"How to use an Arduino to measure preload voltage of ultrasonic transducer and convert to stress"

You can watch the recording on my YouTube Channel here:

Here is a link to the pdf of the whiteboard notes: Webinar 18 notes

Here is a link to the finalized code, which measures voltage and converts it into MPa with the needed inputs: Webinar18_ads1115_20231110122622.zip

Summary

In this webinar, I show how to use an Arduino and the ADS1115 ADC to measure preload voltage of a transducer with high impedance impedance. I have a long discussion about using the ADS1115.

I talk about theory, using the ADS1115, and show live demo and the Arduino code.
