Hi Mike Hope you are ok
Thanks you for your help.
I want to connect between rotary 2 poles 6way and Digit Numeric Display (see Word doc). attached here
Hi Ken
Thank thank you so much
can you tell me
What can of diodes i need to use ?
Zener diodes or signal diodes ?
and what about Resistor (for 5v)
i need to use
I am sorry I am just beginner but i want learn )
Thanks
Roby
The diodes can be common signal types, like 1N4148. The resistor values will depend somewhat on the Vf (forward voltage drop) of the LED digit. Not critical...somewhere between 120Ω and 330Ω. Figure: (4.4-Vf) / 0.02
For the digit, if you could only get a "common-anode" type, just reverse the polarity of all the diodes, and swap the +5V and common.
