HiLetgo 5pcs Piezoelectric Sensor Analog Ceramic Vibration Sensor Module Piezoelectricity for Arduino DIY KIT

In a nutshell, An excellent piezo vibration sensor with the ability to measure A RGB LED is used as a vibration indicator in the video with this sensor connected to an Arduino UNO. It continuously check the piezo sensor for a vibration greater than 0 by reading it repeatedly. The current LED color intensity may be altered to match the intensity of the vibration before moving on to the next color if the vibration is intense enough. The Arduino will stay on the same color if this is not done. To generate a vibration input, I used a pollination wand. I was also able to connect the sensor without any issues.

What is the purpose of this? Those are the drum light bulbs I bought for my drum kit. I have read that piezos can produce a lot of voltage in spikes if they are hit hard enough, up to 90 volts! The 5v that an Arduino can handle is way more than what this project requires.

This is essentially a Zener diode in a circuit, which has a 1Mohm resistor in line so that if the voltage goes too high, it will shut down instead of boiling everything. Even though my project hasn't yet been realized, I have noticed that they seem to be functioning well so far.

They worked just fine for me. It was possible to get these to detect impacts exactly as I needed with this and an ADC. It was also reasonable enough to buy five of them for this price.
