Hi,
When plugged into my computer, the Arduino Giga Display works perfectly, but when using a 9V battery source or plugging into an outlet the screen doesn't initialize. Why would that be? Thank you.
9V batteries are too weak.
Hi, thank you. What would be recommended to use?
If it will not be plugged into a computer, then a wall wart or if it must be on batteries, a power bank of sufficient power.
What would be considered sufficient power? I see in documentation that for a basic sketch needs about 363mA. I read online that alkaline batteries has a capacity of 6-7 amps.
That's correct, are you just running the Blink sketch? If those are non-rechargeable, is that what you want to be changing batteries? If rechargeable, how long do they last.
If this is a battery application, then something like a powerbank of 5AH or 10AH or LiPo or the common 18650 preferably in LiFePO4 chemistry for safety but 1/2 the power, or the new Sodium batteries, very safe cheap but again much less power.
When you state your requirements I can give you a better answer.
Show me the alkalines with 6 to 7 amps.
Thanks for your help thus far. I could be mistaken about the alkaline battery amps, it's just what I saw on Google:
I'm not sure what the minimum amp requirement would be for this project. The sketch does include a WiFi connection, some UI configurations, and touch recognition. I can upload the sketch if that helps.
Just following up with this question: What type and amount of battery would be sufficient to power a Giga with the display shield?
Just following up again.
