    automated physical keystroker

    This kind of user interface. I want to program different predetermined exercises sequences in this walking machine, so I need some apparatus for doing the keystrokes. Let say I want a predetermined exercise routine (five minutes at 10mph 10degrees, 3 minutes at 8 mph 6 degrees, etc) so I only...

    why do we use active filter?

    why do we use active filter basically you can adjust gain

    need help for PIC 16F84A programming

    movwf trisa if you use this : #include pic16f84A.inc list p=16f84A you don't need this PORTA equ 05h TRISA equ 85h PORTB equ 06h TRISB equ 86h

    squared value input voltage

    I'm looking for a simple circuit that squares the value of the input voltage, this is : If I have a 1.2V at the input , the output must be 1.2*1.2 = 1.44V, and so on thanks in advance for your comments.

    what type of transistor do I need? (wave inside)

    Because I have already made a PCB which includes that circuit, and I do not want to modify it too much
