    LM317 And The Magic Smoke

    I'm designing a project which involves a microcontroller sending data over SPI to two SN74HC595N shift registers which, then control some level shifters to turn on and off some 12v end devices. (The MC and the register circuit are on two separate boards) I want to power the shift registers and...

    (Registers/Counters) - What is the final contents of the register?

    The contents of a 8-bit register is initially 01110111. The register is shifted right six times with the serial input being 011001. The same register is then shifted left 4 times with the serial input being 0101. What is the final contents of the register?
