    max current for 28X2

    Hi there, I plan to use a 28X2 to drive 16 LEDs directly from 16 outputs. I have read that the max o/p current is 20mA and the total max current is 90mA. My program lights each individually than flashes all 16 LEDs on and off. Am I right in thinking that this will blow the 28X2 up and I...

    I have just recieved my first Picaxe, an 18x with the starter PCB. It has the 2803A darlington IC on the board. I have read many posts and looked throught the manauls but can not find what voltage the 2803 IC needs. Does it depend on what you are driving? I know to connect the 4.5v to G and V+...

    Reading an encoder

    I am new to the PICAXE (though I have used a Basic Stamp a little) I am hoping to read from an incremental encoder and increment / decrement a 7 segment display. (100 'clcks' one way will display 100, 100 clicks the other way will count down to 0) I know about the phase difference between the...
