+ 5 volts
Connect the other side of the relay coil to + 5 volts (or +12 volts if
using a 12 volt coil). Driving the stamp ouput pin HIGH causes the
ULN2003 output to go LOW, grounding the coil circuit and activating the
coil.
The ULN2003 has 7 Darlington transistor drivers, so you have 6 left over
for other purposes.
