We have an Arduino device that is using a sensor requiring ~12V. Are Step up devices safe? Are there any dangers in terms of current etc?
To elaborate; we plan to run the 5v supply from the arduino board through http://uk.rs-online.com/web/p/dc-dc-converters/0389287/ in order to power https://www.sparkfun.com/datasheets/Sensors/Proximity/SE-10.pdf as the 5v has proved insufficient. 9v batteries have worked so far, but haven't lasted long enough.
Will this work, and how might the circuit look?
