Powering Pro Trinket without direct access

by Xanzimalean on Sat Feb 09, 2019 1:17 am

Writing a simple Arduino program with a trinket involving an accelerometer and a buzzer and I am looking for a way to power it without direct access to the microcontroller or battery. I would prefer to use a 5v inductive charger so that I don't need to have openings to a charging port if at all possible.

The goal is to have the electronic components suspended in siliconized rubber, so it wouldn't be possible to swap out batteries and the project needs to be portable so it can't be plugged in during use.

What would be the best battery and the best way to wire this?

any and all suggestions appreciated! Thanks!

Do you have an idea of the current required by your project? That, and the time you want this to run between recharging will decide the size battery you need.

running this accelerometer: https://www.amazon.com/MPU-6050-MPU6050 ... or+arduino

and 2 of these buzzers: https://www.amazon.com/gp/product/B07LC ... UTF8&psc=1

It will need to run ~2hrs at a time.
