Arduino UNO socket
As I learnt so far is that Arduino UNO board has a socket for power input. The available power input range is between 7V - 20V, but the optimal usage range is 7V-12V. … Here I am wondering:
---> if there is a USB port for power supply, why do we need a power input socket?
---> Or there is a battery on-board to charge? …
