Hello, all! Newbie, here. I'm reading/watching DIY's on the HC-SR04 sensor, and it appears as though I can only hook up one to my Arduino Uno? The reason I say this, is because in these instructions I have, it says to hook up the sensor to the 5V slot on the Arduino and I only see one on the board. Is there another way I can hook up more 5V sensors/devices to my Arduino or should I buy a different arduino?
Also, does anyone have a link to a wiring kit that I should buy to get started on connecting the sensor to the Arduino? I was hoping to buy something with a lot of pieces that might last me a little while for a few projects. Thanks!
You can "split" that 5V to as many things as you like, subject to not trying to draw too much current.
Easiest way is to get a breadboard and a pack of jumper wires. Then take Arduino 5V to the red rail of the breadboard and Arduino GND to the black, then you have as many 5V and Gnd connections as you need.
