Batter isolation

Using Arduino General Electronics
1

Hi! Noob to circuit design and Arduino so I’m drinking from a firehose - please bear with me if this question is silly. Thanks :slight_smile:

I’m working on a project currently where I can some output being displayed on an ILI9341 from an ESP32. The device is intended to be portable and so the plan is to use a battery pack as the power supply. In order to optimize battery life, I was planning on using a switch of sorts to isolate the battery supply. What method is best to achieve this? A tactile button and a code to toggle a relay? Or are there recommendations for a switch I can use so I don’t have to code a toggled relay? Thanks for your kind suggestions.

Just use a standard mechanical switch or pull the plug on the battery, the battery will last a long time when its not connected.

However I suspect you have in mind some form of maybe instant switch on of this 'device', but without a decent explanation of what you are actually trying to do, the forum can only guess.
