AV Work Night
Date: 4.21.16Students: Grant and Clare
Time: 4:30-7:10 PM
Location: Logan HS
Goal: Solder and wire connections to motor and begin experimenting with the optoisolator relay circuit.
We needed to upgrade the crimped wire connections from motor to switch, fuse and other components with soldered connections. Need to purchase a soldering gun as 12 gauge wire is too big for our small soldering irons. Clare was working hard on those connections.
We needed to start experimenting with our relays to see if we needed to use a relay or a motor driver. Grant worked on soldering up a relay to test on our motor with the optoisolator.
After we wired the test circuit together we took it into the shop to try it on the vehicle. The relay would turn the motor on, but when we varied the current through the opotisolator we could not get the motor to stop. We felt we had the relay wired in wrong as we had a +5 V on our optoisolator and it seemed to be isolating our controller as it should do.

More work needs to be done on if a relay or a motor driver would be our best option. Our next test will feature a 18V motor driver to see if we can get a more positive result with output to our motor.
