    Driving motors with atmega

    Is this circuit okay to drive dc motors with atmega? While sending to one signal input other one will be grounded from microcontroller. If not okay what additions or substractions are needed to create ideal h-bridge for dc motors to drive with atmega?

    Controlling DC-Motor from incremental Encoder pulse signals using ATmega88, C code

    I have given the following C-Code to test a 60V DC motor with [gear box ratio 16:1 and incremental encoder to see if the code calculates the speed by reading the Pulse signal as feedback for µcontroller from encoder. The µcontroller is ATmega88A-UA. The encoder RE56-3-1000-TI signals 1000 ppr...
