Claim 18:
19. A system, comprising:
a plurality of trainers comprising first and second trainers,
wherein the first trainer is a programmable logic controller (PLC) trainer comprising:
a set of one of more output terminals configured to provide electrical output signals to control one or more electronic devices on other trainers of the plurality of trainers; and
a PLC configured to generate direct current (DC) output signals based on a user design;

wherein the second trainer comprises:
a set of one of more input terminals;
a rechargeable battery configured to:
generate a DC voltage output; and
provide the DC voltage output to one or more electronic circuits on the second trainer; and

an inverter configured to:
receive a DC voltage from the DC voltage output of the rechargeable battery;
convert the received DC voltage to an alternative current (AC) voltage output; and
provide the AC voltage output to one or more electronic circuits on the second trainer; and

wherein the DC output signals of the PLC are connected to a first output terminal in the set of output terminals of the first trainer.
