I have a radioshack piezo buzzer that is rated for 3-16 volts and a 3 or 5 MA. I tested the current it draws with my dmm and I got the rated MA being drawn. I had used this device on a different project using a BX-24 which has an 8515 as its core. When I use it with my 128, the sound is very faint. I tried it on 2 different pins and the sound was the same. I am pretty new to AVRs. I am pretty sure that I have the pin set to output (DDRx = 1 on the appropriate pin). Any suggestions? -Tony
