Here's the code: // this is quoting the code from the video Will the code for the Uno work with the Mega? Could I simply expand the code by describing more digital pins in the code so I can use the 54 digital pins on the Arduino mega 2560? (the code is abbreviated and shows only the code for two working keys, the rest of the code is just more of the same: copy paste with different button and note numbers).īut of course I would like more keys. Using the Arduino Uno starterkit I succesfully made one with 11 keys as shown in the Youtube tutorial that is mentioned in the code below.

I'll be sure to add in resistors when I build my collaborating partner's instance of this project.I'm new to electronics and Arduino and I would like to make myself a midi keyboard. I don't mean to dispute your experience, and I hope you will afford me the same courtesy. I'm getting away with it, because I just haven't experienced electrons being so unforgiving. I just haven't experienced arduinos failing on this apparently incorrect technique, so in my own interpretation and words. But you have such strong words, even though I don't seem to experience the same level of hardware failure that you are indicating is an eventual certainty. I've burned out LEDs in the past, and the arduino just doesn't seem to do that when I plug 'em in directly. But the only structured learning path for this level of electrical engineering is at universities, and that's just not something I can do with an existing career, mortgage, wife, baby, lack of funds, etc.Īnd this may seem like the most basic principle to you with the resistor on the LED. I wish there was a more structured learning path so I could spare the forums from the horrifyingly stupid newbie stumbles that I'm invariably going to have. And maybe the learning path is just hardwired to include the forums and non-traditional teachers who are of varying teaching techniques. I thought the core purpose of the arduino project is to bring electronics down to the level that artists with no electrical engineering education are able to begin learning about this discipline. However, I feel like it's better than I have the courage to attempt such an ambitious project than to not even attempt it at all, so I'm going to try to put down my feeling of stupidity and push forward. Ok, I think I feel stupid enough, so no further responses required. When I use the digital pins with the Button library, I have them connected to the digital pin and to ground, and then I address them as PULLUP and they work like a charm. Am I totally missing the point or misusing the terminology? I'm one of the horde of untrained enthusiasts. The results I got was that it doesn't appear to be sending current out to let the switch complete the circuit to ground. I was hoping to use the Button HAL Arduino Playground - Button Library for this implementation, but if I can't no big deal, I'd love to understand how I can do this the regular way if the HAL can't do this for this hardware in this instance. I was expecting to be able to address the analog pin as a digital input and use it like I am successfully addressing 20 other tact inputs on my project using the digital pins. I do realize that the diagram appears to be pointing at analog 0, which would be digital 54. I am actually paying attention to which pin is connected and which pin is addressed in my code. This is currently how my circuit is wired up:Īnd I'm only using the diagram as a loose translation of how it's wired. Perhaps I need a wiring diagram to explain how I did what I did and what the results i was expecting, and then the results I got.

I did indeed try using them as pullup digital inputs, thank you for asking me to clarify, I will be happy to do so in pursuit of knowledge on how to do this correctly.
