For the Max patch, I needed to translate the data read from the sensor into one value. By using the message box, I was able to see the values that were output when I tapped the sensor. I created a range 0 to 300 and have it bang if the value is higher than 300, because the value when tapped is usually higher than 300. The bang triggers the on/off switch for the kick bass drum. I added a 300 millisecond delay to the bang to act as an off button so once the drum is turned on and produces a sound, it will then turn off. | For the Max patch, I needed to translate the data read from the sensor into one value.

As you can see, I was able to hook up 5 Piezo sensors to the Arduino by using a breadboard, alligator clips, jumper cables, and 1M resistors. One problem I encountered was that when I hooked up more than one sensor, there would be some noise, some of the sensors would constantly output a low signal when other sensors were struck, but the number is usually very low and negated because of the threshold that I put in the Arduino and Max/MSP code. When each sensor is struck it outputs the assigned drum noise. | As you can see, I was able to hook up 5 Piezo sensors to the Arduino by using a breadboard, alligator clips, jumper cables, and 1M resistors.
