Securing programmable IC chips Answered
I've just started playing with Arduino boards and programming and I am curious about firmware or downloading a program to a chip upon completion so the project remains so I can keep it intact after I remove the Arduino interface. Can you buy inexpensive chips and download a program to the chip with all the instructions on it so I don't have to leave the Arduino board connected to it. I've heard there are inexpensive one time chips that you can download too and that's pretty much it. Once the program is in, its in and you can't reprogram it again so my questions are this 1) can this be done? 2) does anyone have an Instructable for a project that uses this, and finally, where can I get such programmable chips? Any assistance or advise is most appreciated.
