this post is a little late so sorry guys. anyways after talking to carl, he suggested i use a relay to activate spi-dog. the relay acts as a switch, that is activated when electricity is running through it. as seen in the image above the black box object on the circuit board is the relay. when i detach the red wire going into it the relay, the relay has no power and the gate is closed. when i place the red wire on the relay a magnetic coil closes the switch and completes the circuit causing the red LED lights up.
in going into further with this discovery I think that I need to learn more about photo sensors. from my understanding a photo sensor is a resistor, but I need to use the photo sensor as a trigger.
in other new i’m focusing my research on synaesthesia in relation to hearing. one interesting article i found was call “the fire of Prometheus”: music-kinetic art experiments in the USSR. i’m still reading up on this so i’ll let you guys know on my findings later.
