 | | RCX Voltage Question
|
| If you connect two motors to the same output port, will they each get 4.5 volts, or will it take current from the other outputs? (22 years ago, 1-Jan-03, to lugnet.robotics)

I don't know how many motors it takes (I'd guess one) to reach the limit, but from then on extra motors will not (...) (22 years ago, 2-Jan-03, to lugnet.robotics)
