Turtle Pen Solenoid

I am going to use the reverse board to control my PiCy turtle motors. I just wanted to ask how I could extend the board to control a solenoid so I can ask the turtle to raise and lower a pen?

Thanks in advance

Unfortunately the PicoBorg Reverse only has the two motor outputs it can control.
It will not be able to control a solenoid and two independent motors.

Since this is a PiCy upgrade you could make use of the old PicoBorg to drive the solenoid for you.
You would need to connect both boards to the Raspberry Pi at the same time.
This can be done using a TriBorg or by soldering some pins to attach the 3-pin cables on top of the PicoBorg.

Alternatively you can make a simple solenoid drive circuit which is connected directly to the GPIO of the Raspberry Pi itself.
There is a good example of this in David Hunt's Drop Pi example:
