Amplifying ATmega8 signals
May 28, 2010
I am doing my final project for school at the moment.
I have a bit of a problem.
I use my ATmega8 with a BD243C transistor to switch a relay.
Now is the problem that the signal that goes to the transistor is to small to fully switch the relay. I was wondering if I could use this(http://www.datasheetcatalog.com/datasheets_pdf/T/L/0/7/TL074CN.shtml) TL074CN IC for amplifying the ATmega8 signal and so fully switch the relay. Can this be done?
I have not much time left to finish this project, so I would appreciat all help.
