In the later versions I have a menu option to switch between the buzzer or an external PC Speaker driven through an LM386 Amplifier. The transistor is just a 2n2222, I will update the final post with a full schematic over the next week or so. If you want to try the LM386, the circuit is here - http://rcarduino.blogspot.com/2012/08/adding-audio-to-arduino-projects.html<br /><br />If you contact me through the Arduino Forum I will send you a zip of the latest version.<br /><br />Duane BCan_I_Trade?https://www.blogger.com/profile/07867684474123805993noreply@blogger.comtag:blogger.com,1999:blog-7214097671310478681.post-73568928513294709622012-11-10T06:57:57.944-08:002012-11-10T06:57:57.944-08:00what number of NPN transister to drive buzzer ?

I will set myself a deadline for a decision and start publishing shortly.<br /><br />Duane BCan_I_Trade?https://www.blogger.com/profile/07867684474123805993noreply@blogger.comtag:blogger.com,1999:blog-7214097671310478681.post-71479026781781956082012-05-31T07:01:34.336-07:002012-05-31T07:01:34.336-07:00Hi!
