 ### Stepping Up
 
-On the contrary to stepping down the voltage using simple voltage divider, to **step up** the voltage, due to uncompatible TTL threshold scenario as in the previous, you will need to use a little bit more constructive electric circuit by using diodes. Following circuit shows how it is done.
