Web9 mrt. 2024 · The piezo is attached to analog pin 0 with a 1 Megohm resistor in between the two legs. The placement of the resistor is used to save the piezo from damage from extra current. Without it, the analog pin might not be capable of reading the piezo's signal. Code. In the code below, the incoming piezo data is compared to a threshold value set by ... WebA1 megohm resistor allows any static charge, whether from the bench through the product and then through the grounded person or operator or vice-versa, to discharge completely over time, typically less than 1 second. Without the 1-meg resistance, the static discharge would be an instantaneous drain directly to ground through the product.
