I have a problem because I want to power my esp32 power bank and I want to create an artificial pulse on one of the esp32 pins using a resistor to maintain the power consumption on the power bank and I don't know exactly what resistor to use and how to do it, can anyone help me or give me some advice?
How much current does the power bank require to keep it turned on ?
Is it even worth designing your own ?
That is not a great idea, you can damage the processor but in any case you will cause it to warm up a bit. It has a limit on the total amount of current it can supply. You need to check the data sheet of the particular processor you are using. Using a simple LED and a MOSFET would serve two purposes, it would draw the current and keep the load off of the micro. An added benefit would be it will be blinking letting you know your code is running.
You can size it however you need and note it is powered from the supply not the processor. In your case it would be the power bank.
What is the difference between a real pulse and an artificial one?
If you are using WiFi your board may already be drawing enough current to keep the power bank alive.
Have you tested it?
