6 lines driven by 3 wires.
The schema is developed to work with some controllers (Arduino-like).
6 lines are represented here as 6 LEDs.
Also, here is an additional transistor to control LED line dimming.
To control dimming, instead potentiometer, connect the transistor to the controller's PWM pin.
In case you do not need a dimming part, just remove the transistor and connect the main + line directly to the voltage + source (like it is shown on the switcher second position).
By default, all terminals have level 0.
Turning on some particular line is a combination of one 1 on the left side and one 1 on the right side.
A high-level signal is not allowed simultaneously on the same transistor pair side.
For:
aa
bb
cc
The following combinations could cause short circuits on transistors: AA, BB, CC.
Please use the following combination:
AB, AC, BA, BC, CA, CB.
In addition, this schema allows turning on two lines simultaneously (it is beneficial for reducing blinking in case all six lines need to be turned on). So the following combinations are allowed:
AB+AC
BA+BC
CA+CB
