After getting the relay triggering for the proper 2 second interval, it was time for the first real test.
We wired up our KNEX motor to the relay, connected it all to our light switch face plate, held our breaths, and pulled the trigger wire.
It worked! “Like a Charm”.
This project is going to work out.
This first test was really important, since it helped us realize that we would need to mount the motor to the breadboard, plus if we stuck the batteries underneath the breadboard, it would put the motor at the right angle (~30 degrees) so that it would actually reach the light switch.
