I just bought an Arduino mainly to reset the chips on my toner cartridge (which is telling my printer that it's out of toner when it has plenty left). I found a webpage that tells how to do it if you are using a Discovery kit.
How would I customize this so I can do it on an Arduino? I'm totally new to the Arduino and don't have much electronics experience, so very basic step-by-step instructions would be greatly appreciated if anyone would be so kind. Thanks, much!
You seem to have basic step by step instructions for this other kit. Why don't you buy that and use it like it says if you don't know how to do these sorts of things.
This isn't a place where you just plop down a set of requirements and a bunch of fairies magically pop out a custom tutorial for you. This is a place to get help while you do the learning and coding. I'll point you to the top of the screen where it says "RESOURCES". That will get you started learning Arduino. Come and ask when you have any specific needs. This is going to take some time to learn and you're going to be making a lot of projects in the learning process that don't have jack to do with toner cartridges. Finally after some time you'll know a bit more and you'll know what you need to do with your toner cartridges.
If you're not into that, then just buy the stuff for the instruction set you already have.
