I am a behaviorist and I have never done any programming or computer building, however I am attempting to build a stuffed dog toy with pressure sensors in the back and tail to teach children I work with how to pet an animal appropriately. I would like to have an averse speaker sound when the person “pets” the pressure sensor on the toy too hard (more than 5lbs) it would also be cool if the pressure feedback was adjustable. Can anyone give me a direction to go with this? Thanks in advance
Hello behaviordude,
I would suggest looking into using our [Qwiic MP3 Trigger and [Qwiic Micro SAMD21 Dev Board.
You can use the Qwiic Micro to read the sensor values and trigger an MP3 track to play when the petting is too hard. There are “Poke Home” connectors that easily allow you to connect a speaker with wires or an audio jack for a standard cable.
I hope this points you in the right direction.](SparkFun Qwiic Micro - SAMD21 Development Board - DEV-15423 - SparkFun Electronics)](SparkFun Qwiic MP3 Trigger - DEV-15165 - SparkFun Electronics)
Perfect! would this work if I just want a bell sound to play as well? what type of sensor would you recommend?
I can’t recommend any one sensor. I would suggest browsing through our [Flex/Force sensors to see if there is one to match your needs.
The MP3 trigger plays files off of a microSD card. You can use the Qwiic Micro to tell the MP3 trigger to play a variety of sounds. Just make sure to read all the hookups and getting started guides.
I would recommend that if you’ve never worked with electronics before to do your research. We have an [Engineering Essentials educational page as well as a whole bunch of [tutorials for many topics.
I wish you the best of luck on your project.](https://learn.sparkfun.com/tutorials)](https://www.sparkfun.com/engineering_essentials)](https://learn.sparkfun.com/tutorials/sparkfun-qwiic-micro-samd21e-hookup-guide?_ga=2.253036175.746112717.1581956734-2114068872.1578439588)](https://learn.sparkfun.com/tutorials/qwiic-mp3-trigger-hookup-guide?_ga=2.253036175.746112717.1581956734-2114068872.1578439588)](https://www.sparkfun.com/categories/143)
