When Group B is ready to move on, take both of your breadboards and move all the jumpers running from their Arduino into the same pins on your Arduino, so that everything is wired into one microcontroller (you need not physically move the components, but rather just their jumpers, leaving two breadboards side by side. They can lock together!). Once this is done, follow the link below to jump back into the normal lab manual together.
