Hai,
Extreme n00bie, here. I am a designer in Chicago and need to get this thing project done by June 20th or I lose about $150,000 in Grad School Money. (long story).
The jist.
I need a PIR sensor, when it detects movement, to trigger a programmed pattern for a push-style solenoid to play. Basically, I need the solenoid to play a basic beat or rhythm for 60 seconds when someone moves past the sensor.
Also, if completed in time, this project may be funded and installed (up to 50 of these things) locally on abandoned infrastructure in the Chicagoland area, so it's power source must be some kind of battery array. I would prefer solar, but I don't think that's feasible.
WHAT I (THINK I )KNOW:
I'm thinking this solenoid: (Solenoid - 36v - ROB-10391 - SparkFun Electronics)
*probably having to run at least 12v
This PIR sensor: (PIR (motion) sensor : ID 189 : $9.95 : Adafruit Industries, Unique & fun DIY electronics and kits)
I want the solenoid to play a pattern that is a cross between (- YouTube) and something like this (Solenoid Robot Drummer playing along to Very Ape by Nirvana - YouTube)
Remember, this thing has got to be on an abandoned train line (or someplace similar) so I can't have a computer running abelton attached to it.
What I need to know:
I need to know if I need a power driver shield for the arduino.
Should I get my hands on a MidiTron? If so, what type of circuit configuration/arduino programming do I need in order to get this thing to play a pattern when the PIR sensor detects motion?
Sorry for all the clearly nubile questions, I just need to get this thing going and I'm startin to get THE FEAR.
attached: are images of this THING as it will appear on a streetpole or power pole. The solenoid pushes the (blue) arm to strike the pole like a hammer on a piano strikes a string.
