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: https://youtu.be/EIgjLZQjZQw 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. *** Announcement *** My next webinar will be on Friday, November 17, 2023 at 11AM EST. I will cover "How to measure the d33 coefficient of a piezo crystal using a known applied force” Here is the link to sign up for the upcoming webinar: https://www.ultrasonicadvisors.com/monthly-ultrasonic-webinar
