Camera Trigger // Nick Ricci & Naoki Hisamoto

To trigger the camera, we dismantled a previously existing remote shutter trigger. We observed that the trigger works in two phases. First, a connection is made that activates the focus of the camera. The second connection made takes the picture. These connections are made when two metal plates touch. We simply desoldered the wires from the metal plates and replaced them with buttons on a breadboard. However, we wanted to find a way to be able to trigger the camera using the arduino. We discovered relays which were switches activated through electromagnets. We found a diagram online using a transistor to first activate the coil which flips the switch and using a diode as well to prevent any voltage to flow back into the Arduino which is a possible outcome of using relays. By doing this, we are able to code two relays to switch on one after another to simulate what the physical trigger button does.
