I'm looking to build an animal deterrent device. I need the schematic and parts list drawn up so I can assemble some test units. When I say schematic, I need it to be a schematic for dummies. Its been a long time since I worked with electronics and I’ve forgotten almost everything. I need it to be cheap and simple.
Requirements
When motion is detected I want 3 things to happen
1. 2 LED’s come on. Time can be 20 seconds or so
2. Piezo or something similar to activate for 10 seconds or so
3. Vibrating device, like in cell phones to come on for 10 seconds or so. If possible not at same time as piezo
I would like it to be solar powered with a battery. If for some reason solar is cost prohibited I would be willing to use regular batteries such at 9v or AA. It needs to operate day or night if it matters.
Im looking to build 10 or so to start for testing.
If you could please estimate what you think it would cost based on the 10+ qty.
Like I said I need them to be cheap
From my limitied experience I was thinking something like 555 or 556 timers
If something like a picaxe or aurdino board is needed to program some other type of chip that is fine as long as it is reasonable priced, but cost is my main concern.

Hello, I can provide the solotion. This could be done using motion sensor and other related parts. The option of using any programable chip is there, but not necessary. i will discuss it in more detail once the con Більше
Hi I am an EE graduate and have extensive experience in circuit design. I'd suggest Arduino platform for you as you need to detect motion as well so you'll need a PIR motion detector sensor to input to the Arduino. For Більше
HI norcalwilliam so as your project interesting, we will start motion detecting sensor iezo as you advised because that will be cost affective and also reliable and for controller we will use a Більше
Using 555 or any timer IC or a ready made won't be a very good idea because it will cause Bill of Material to be high and limited flexibility. For this kind of project we can use a tiny microcontroller like PIC12 or ev Більше
Small and cheap arduino uno pro mini, motion sensor, buzzer, leds and vibrator, solar cell. All components stay under 10..12$.
