Hi, I am trying to use 4 Ultrasonic Sensors HC-SR04, and 3-4 other sensors such as BNO055 to an Arduino UNO, can UNO drive them by its 5V or need an external 5V? Thanks Adam

The question is more what current can your power supply offer to the Arduino (and the voltage you feed the arduino with) You need 15mA per HC-SR04 if they all trigger at the same time (which comes with technical challenges, if they only shoot one at a time the quiescent current < 2mA) a BNO055 wo…

Thanks.
I'll use an external 5V.
