#136351 - only have 5V supply Responding to: ???'s previous message |
hi,
the thing is, i only have available a 5V supply, since we're using the lab-pro51 prototyping board in our class. and even with the 5V directly connected to it, the buzzer sounds pretty weak, since it can take up 16V (i think thats the reason), so i guess i'm gonna have to live with it. is there a simple way to get 16V to the buzzer? thanks |
