I plan on using my Uno to program several Atmega328s and embed them in simple circuits which I would like to encapsulate. Is it necessary to have a reset button in embedded circuits? The circuits are simple i/o (no serial). I googled until my eyes were blurry but could not find an answer to this very basic question.
No, you do not need a reset button. But, I will say it’s good in-case the programming goes hay-wire for any reason. You will also need to have a reset circuit to program the MCU. Search for standalone arduino and arduino as ISP.
Thanks codlink. I read your Arduino references and I understand now.
