    74166 8 bit shift registers

    Thanks for the reply but my chip looks a little different. I was wondering how do I tell the chip to start outputting and shifting. Shift diagram is bellow.

    74166 8 bit shift registers

    Hi I checked online but I couldn't find a data sheet for 74166 8 bit shift registers. Does any on know where I can find a full data sheet for it. The 74166 register is the only register my circuit simulation app (Icirciut) provides. Thanks

    falstad

    Hello I am using falstad the circuit simulator. falstad has a really useful user interface that I enjoy. But falstad can't handle complex circuits or more than one circuit at time. I was wondering is there program with similar user interface like falstad, but it can handle complex circuits...

    Interface microprocessor with microcontroller

    Hello I am trying to interface a microprocessor with a microcontroller. I am not using anything fancy like an Arduino or PC. I just have intel x86 chip with dip packaging and a microcontroller chip with dip packaging. I was wondering how would I connect the processor to the controller using...

    Using transistors

    Hello I am trying to use a npn transistor, but the circuit simulation program says I have one bad connection. I am not sure what I am doing wrong. I am providing a week signal to the transistor base (0.7v) and I am providing 9 volts to the collector. My load is the resistor. Based on the...

    Transistors amplification

    Hello I know transistor amplifies current, but I am a bit confused about that. Can I power a component that requires 10A (ex. motor) using 5A and a transistor? Can the transistor increase 5A to 10A? What will happen to the voltage in this situation will the output voltage also increase? Thank...

    Help with simple LED circuit

    If you are looking for a power source you can use a battery to provide the power. On this website you will find a chart that will tell you how many volts different color LED's need. Each resistor is color coded and you can look up the amount resistance on google. Use ohm's law to figure out...

    Op Amp

    Okay I think I figured it out, I had the wrong wiring. I see a gain in the output when I move the resistor from the first pin to the third pin.

    Op Amp

    I set up an amplifier circuit using tlc272cp op amp I check the current using an multimeter but I don't see any gain I was wondering if some one could tell me where I am going wrong? I attached a picture of the circuit
