I'm trying my first DIY electronics project. Here it is:

I don't understand how to ground this circuit. What do I connect to
the black termincal from the wall? What do I connect to the green
terminal? What does the dashed line mean?

(assuming you live in the US and you are connecting this to 120 volts)
The black wire in a power cord (or the narrow flat slot in the
receptacle) is the wire that has voltage with respect to ground,
called "hot". It would connect to the 120 volt orange transformer wire.

The white wire in a power cord (or the wide flat slot in the
receptacle) carries load current, but is grounded back at the power
panel, so it has very little voltage with respect to ground (only the
wire drop caused by current passing through the wire). It connects to
the white wire on the transformer.

The green wire in a power cord (or the round hole in the receptacle)
is safety ground, which does not carry load current, and is grounded
back at the power panel. No connections are shown for it, in this
schematic, but if you bolt the transformer core down, it would be
connected to one of those bolts.

Be sure to well tape all wires not used, as well as the connections
you make. There will be lots more voltage on some of the unused wires
than there are on the ones you connect. The black/white (probably
black wire with white stripe) may have the highest voltage.

This advice is worth what you paid for it.

This first DIY project is a potential killer. Be very careful to
touch no part of this thing when it is powered. If you kill yourself,
please don't sue me.

from their website:

Core and coil ballasts are insulated with a varnish-like material. This
material must be penetrated at the point where the ground connection is made
to ensure a good connection. This connection can be made when mounting the
ballast to the luminaire, by using a star washer in combination with one of
the mounting bolts.

that's how you connect the green wire.
