Hi,
I would like to use an ATMEGA32 (power by 5VDC) to operate 9 solenoids, 1 photoeye, and 8 inductive proximity sensors. Below are some specs on these items:
Solenoids - SMC part# SY3120-6LOU-N3 powered with 12VDC system supply. Digital ouputs need to sink current.

Proximity Sensors - HTM Electronics part# LCM1-1812N-A3U2 powered with 12VDC system supply. VOH = approx. 12V (off/sensing) and VOL = < 1V (on/sensing).

Photoeye - Omron part# E3Z-D62 powered with 12VDC system supply.

I'm struggling with the best way to do the level translation from 12V to 5V from the inputs. Some ideas that I've considered are diode clamps and optocouplers but I'm not sure which might be best or if there is a better way of doing it out there. As for the outputs I'm considering using some ULN2003A ics to sink the current for the solenoid valves.
I am pretty new to the electronics world so any suggesstions, comments, insights, etc. would be greatly appreciated.
Thanks
