So..... (just to make sure I understand all this): if I solder wires to those seven points on my tank's board and then connect these to digital ports on my Arduino, I can control the tank's movement with e.g. an ultrasonic sensor, point the gun at e.g. a heat source, fire it if the cat walks in front of an ir heat sensor, etc.? I'm new to this stuff and a tad geriatric as well, so I need things spelled out to me...
