Guest Electronics48 Posted February 16, 2014 Report Share Posted February 16, 2014 Hi,I am new to electronics and i am making a simple burglar alarm on a breadboard. It consists of a pull up button, a monostable and 2 astables and a piezo transducer. However i cannot get my piezo transducer to work properly as it will beep all the time. Could you please look at the picture attached to see if you can spot any wrong connections or anything you would recommend changing in order for it to work?
