International modul
Hey
I’m on an It technology education i Denmark.
we are having a International module with in cloud some kind of an international aspect.
This forum hopefully is going to be my aspect.
Now my project and problem. Where i need your help.
I’m making a ultrasound system:
I already made one with a transmitter and receiver.
But my problem is that i only have 30cm of range and i would like to have 8-10 meter.
If the attachment dosen't work i wuld like some help for that to.
What i would like you to do is to guide me on what needs to be done for achieve my goals.
Best regards

Re: International modul
I think there may be an error in the transmitter circuit. The bottom end of the 4.7k RP should be disconnected from R2 and pin 3 of the LM555, and instead connected to the +9 v rail (pine 4 & 8 of the LM555). Pin 3 should be connected to the top end of R2 only.
