More newbie questions (sorry)

[diegop]

Hi guys,

I received my order and I was playing around with the hardware. I have some more newbie questions if you don't mind... So what I have in mind is something like an autonomous IR receiver. For that, I thought of adding a few more elements to the Uno:

•I saw the IR tutorial but I'd like to plug the IR receiver to the Uno. So I think I'll need this right (is there any other cheaper version)? https://www.adafruit.com/products/826 . As I mentioned before, I sort of want to make it self-contained and I'd want to avoid using a breadboard.

•To make it autonomous, it needs power; I thought of ordering this shield: https://www.adafruit.com/products/2078. I already have a Li-Polymer Battery 3.7V 2000mAh someone else gave me. I'm not sure I need a power booster but it's nice since it can stack up with the Uno.

• I'd also want to print the input I receive (I bought the tiny remote control too) and display the information in a small (cheap) screen (e.g. "Sequence '1234' received..."). Would this one https://www.adafruit.com/products/772 do the job? Is it stackable with the Uno and the PowerBoost shield?

Thoughts? Do you think they can be stacked without issues? Or do you have other recommendations?

Cheers

You need the power booster.

Is that an adafruit battery you have? We don't guarantee that the PowerBoost will work with third-party batteries. Sometimes the polarity is reversed, and sometimes they batteries don't have the right chemistry to work with the powerboost charger. It could be unsafe to use.


The PowerBoost shield and the LCD shield will work together.

Attaching the IR receiver is a bit of a problem - there are no prototyping areas on those shields. You could add a ProtoShield to the stack:
