[joecabezas]

Hello, I want to make a piezo buzzer sound, there is a way to do this?, is pi_piper able to pwm?, thanks

not the released gem, nor the develop branch. But their is two forks with this implementation :

• mine using only the bcm library : https://github.com/elmatou/pi_piper
• another relying on piblaster, a binary allowing PWM software or hardware

thanks, how to install your library?

not particularly a pi_piper question, use bundler ?

gem 'nokogiri', :git => 'https://github.com/tenderlove/nokogiri.git'

just change je the gem name and the github url.
