Well, I’m new to arduino. The questions might be repeats, and if so please bare with me.
Arduino looks like a fun platform to start playing with, and very easy at that. Both of these are appealing to me. I plan on buying a USB board to get started.
I have a question about using arduino in the “real-world” though.
I have a project in mind, and want to use the arduino platform for development (programming the chip). BUT, once I get the chip working with the circuit I want to be able to pop it into a bare-bones type circuit.
Once it works, I don’t need to be able to re-program (without removing it and putting it back in the arduino board). I just need it to bootup, and correctly respond to input and output. IS this possible, or once programmed are the looked into the arduino boards?
Can someone point me in the right direction, or give me some examples of this? I’m a little confused on what is necessary to just have the chip bootup and run the currently loaded sketch. Will the supply voltage, GRD, and clock pins be sufficient? Are the RX, TX, reset pins needed in this setup?
If you get the arduino mini, you can’t just pop off the processor and use it in you own circuit.
If you buy one of the DIP based ones, you can do just that.
As you say, the minimum you need to supply is the V+/GND, crystal/resonator (you can even do away with this once you develop a few more skills), a filtering capacitor on the supply and a pullup resistor on the reset pin.
BTW this is probably the most common question related to arduino there are HEAPS of simmilar question, plus great answers including diagrams on the Arduino forum in the FAQ section.
Yeah, I know that I can’t pop the chip off the mini. I meant that the mini looks like a bare-bones board. Circuitry mimicking the mini (but with a non SM packaging for the IC) on my board would seem to perform the way I’d want.
It would seem only 5v, GND, and the crystal are needed.
Thanks for the tip on the arduino forum. I honestly didn’t even realize there was one!
