Hi Ken,
I have access to a maker space so can get some help. How do I control the pins?
Is it like driving motors with an HBridge?

Here is the part from one of the braille sells that I have been playing with.
This was similar to the bp18 kgs cells.
"circuit is powered up by a 12V DC adapter. A DC-to-DC
converter is used to convert the 12V input voltage to 200V
output voltage that is used to activate the piezoelectric "
So you would have to build a circuit to do that or buy one either way you would
have to know how to connect everything up for the power. Controlling the pins
is simple though.
Ken

Hi Ken,
Many thanks. Can't the pi do the processing and drive the cells instead of
having a dedicated board?
