    How much is the maximum outputs that can be attached to an Arduino ?


      For my robot I need to have 3 relay modules , 5 ultrasonic distance sensors , radio transmitting 433mhz module and a piezo buzzer . So is the current outputted by the arduino enough to operate those ? and if its required to add  an external output input how to add ?
