How to drive passive buzzer with nonosdk?
Posted: Sat Mar 30, 2019 10:16 pmI can use the tone library in Arduino IDE( but compiling code takes too long, slow PC), so I want to use the native nonosdk but I cannot find any code for driving the passive buzzer. Can anyone post a code?
Hardware
Passive buzzer is connected to a 2n3904 transistor and 100 ohm resistor, the base of the transistor is connected to GPIO14, I am using a wemos d1 mini, PWM is needed for this?
