    I am about to make a circuit to deter deer from eating some plants. I plan to make the circuit activated:

    A: when dark (this is when the deer come)
    B: when PIR sensor activated (the PIR sensor I am planning on using senses up to 30 ft away!)


    Stage 1 creation:

    option 1:senses dark and PIR activation, output to buzzer
    option 2:" " output to lights
    option 3:" " output to motor

    Stage 2 charging:

    Because the circuit is only needed at night this leaves open the possibility for solar charging, I will however need to be a bit more experienced before I can create a system to stop overcharging.

    I am going to make it output to a loud buzzer to begin with, hopefully this may scare them however if this is ineffective I am going to have to use bright, flashing lights or if this does not work I will try movement output.
