[sebastianpj]

Hello ,
I am using Raspberry pi3 in my project, I connected a Buzzer on gpio4. when i tried to acivate the buzzer, this pin will go to output mode and set as high, buzzer work for few seconds and then it stops. When I check gpio readall , it showing the pin is in input mode and value is 0.
I tried the above steps in my another pi, it also showing same.
Kindly help me to fix this problem.

Hi.

For us to be able to help you we need more information.
please post the code you are using to drive your buzzer as a start ( please use code tags to post your code) , seeing as you say it works for a while I assume its connected correctly.

Also check if 1-wire is activated in /boot/config.txt; check for a line with 'dtoverlay=w1-gpio' in that file.
