How do I use a logic level converter?

CrossRoads:
If you are thinking it will make 5V to power (the ping sensor?) it will not do that.
For that you need a boost regulator, such as:
Pololu 5V Step-Up Voltage Regulator U1V11F5

Very glad I read this post. Thanks very much for this, Crossroads.

I have since ordered a few of said regulators (slightly different model) for use with a 3.3v arduino and an SR04.

I was wondering if there's a schematic online to show me how to wire this before I have to come o here and ask about it? :wink:

Many thanks!
