Well this definitely has me excited now!
I did a bit of reading after my last post, and realised that I would need a pot to control the contrast of an LCD display (Is there any other way??)
Your robot looks good zitron - what is that big capacitor doing though? How necessary are they for projects?
Also, I bought both an octocoupler and transistors, isn't that all I need to turn things on and off which use another source of power?
