So I made a homemade circuit using atmega328p-pu 2x22pf caps, 16Mhz crystal a led with resistor for testing and a AMS1117 5.0V which is similar to a LM1117 from the data sheet they got some caps as well but i didnt added any. (yes i added a 1k resisgor on reset)
My problem is when i plug the battery the regulator provides exact 5V on output but using the besic example of blinking led my led doesnt even blink or blinks only for few ms and only once in a random time or when i plug and unplug the battery.
Any ideas that can cause that? and yes i triple checked the circuit and every component to be connected and working. Could this be because i dont have caps on the regulator?
I dont have tantalium caps as the datasheet says could i use electritic instead ? and what value ?
