turn on a 120VAC lamp
using
a piezo-electric vibration sensor
also have light detector so it won't stay on during the day
* relay (isolation from 120VAC)
* transistor to control relay
* piezo sensor
* light sensor
* magic software to make it all work perfectly
* circuit
Current Highest risk: I am not sure how to make the pizo sensor work.
Current second highest risk: sensor imput design needs to be fixed.
Current task: Making a compact circuit design for soldering on wednesdays class.
Tasks for Wednesday
-solder in 5v power bar
-disconnect middle channle from arduino
-
Materials :
I now have: diodes, electrical tape, 30ft black 10ga eletrical wire 120v rated,
I need : red electrical wire 120v rated, a soldering iron.
