greetings, Hello everyone, my name is Andy, I work as a full time computer teacher and my time has been spent teaching various courses to all sorts of people and corporate clients. I have always liked electronics and I even took many electronic courses in my studies, but it was a 1 year intensive and frankly you didn't have time to get into it.. all you had was jump from one module to another and learn as much as you can for the exam, then go to the next module.. so in other words, I know a lot of bits and pieces of electronics. Although I have lots of experience running an SMT assembly line, Pick and Place machines, Paste machines etc.. I used to program and run various machines and I did pre-oven inspection and quality control. I did tons of soldering and even hand soldered surface mount circuits. So putting stuff together isn't a problem, but I lack very basic electronic theory knowledge. I can read schematics and put stuff together but I have never designed anything myself. I have been purchasing many electronics books and books on robotics and PICs. My current goal may be ultra simple, but I need help. I would like to build a small circuit that would be similar to a BASIC stamp 1. Something which I can connect to a 9v battery and then program in ASM to turn 8 different LEDs on and off (or anything really). I know Don McKenzie answered my original post in comp.robotics.misc with a link to his dt203. But I don't want something I have to order, I want something I can build on a proto board and which has ONLY what I asked for above. Just a very simple circuit that I can plug my programmed PIC16f84 into and then press a push button switch to run the program press again to reset. Thats all. My goal with this is simply to be able to have the circuit.. then concentrate on my assembly programming and seeing what I can do with those basic i/o lines. I feel that once I have played around with it long enough, the rest will come very easy. I just need this basic circuit to get me started. I've roamed over 100 PIC links this week and haven't found anything this simple. I am thinking of purchasing the book Easy Pic'n, which seems to start from the lowest possible point (which is where I am) and apparently contains such a circuit. I would like to know if anyone here can point me to a circuit like this so I can avoid having to order a 50$CA book which will take a few weeks to arrive. Thanks for your time and sorry about the long post. Andy
