Using an optocoupler ?
i got a few opocouplers , MOC3023
I read the data sheet and it says that the input voltage for the control side is about 1.2v
I want to use it with an arduino uno , any idea how to reduce the voltage from 5v to 1.2v?
here is the link for the data sheet http://www.fairchildsemi.com/ds/MO/MOC3023M.pdf
Thank you in advance
