Hi:
We Teensy + + 2.0, the Teensy 3.1 and Arduino UNO R3. We also have some PIC in case we need to do as an extra supplement if needed as well as more digital ports as inputs or outputs.
PIC16F88
PIC16F886 / 7
PIC18F2550/4550
It is centrally controlled by microcontroller 132 independent Leds, nothing about 3 LEDs in series and things like these. In reality there are many 7-segment display and others are normal single LED.
33 plus 13 push switches are used. A total of 46.
My intention was not to use tricks to cut display scan your email or make it more streamlined to save costs, this time I do not, and programming easier.
What worries me is that I should not use the LED directly or microcontrollers, I use an external 5V power source.
A part of it, has a potentiometer to control the brightness of the LED.
Taking all written.
How do you design?
Add any information to work me great.
