    Wire transmission(15 mtrs) to send data & control signals for cascaded shift register

    Re: Wire transmission(15 mtrs) to send data & control signals for cascaded shift regi Hi, There is nothing to hide. My neighbor gave a project and the project was 'drip irrigation' that would give water for numerous plants separately according to time. Available control board was broken so I...

    Wire transmission(15 mtrs) to send data & control signals for cascaded shift register

    Re: Wire transmission(15 mtrs) to send data & control signals for cascaded shift regi I'm in the stage of starting of my project so I didn't have circuit only prior idea. Thanks for understanding and I just want to make my project as simple. On receiver side I using 15V so I went to CD4094...

    Wire transmission(15 mtrs) to send data & control signals for cascaded shift register

    Re: Wire transmission(15 mtrs) to send data & control signals for cascaded shift regi I thought that sending data via MOSFET with little high voltage means there is no voltage lag or signal loss at sender & receiver side and also 3 phase- 5 HP motor will be placed in that room so only I decided...

    Wire transmission(15 mtrs) to send data & control signals for cascaded shift register

    Wire transmission(15 mtrs) to send data & control signals for cascaded shift register I'm trying to send 4 kbps data from micro-controller(sender) to cascaded shift register IC(receiver). In this scenario distance between micro-controller and shift register is 15 meters. On receiver side 512...

    [SOLVED] Could make any problem if microcontroller and more relay ground connected same

    Hi, I'm planning to control more relay using decoding technique by the use of micro-controller. Talking to relay we may pick normal 12V, 40mA relay. I'd no problem upto 5 relay. If increased more emf or back emf or any other things reflect back to controller if ground connected same.

    [SOLVED] Buffer output to microcontroller input

    Hi, Fine, why we use 10k serially, is only for limiting current? Then what about buffer output to micro-controller input?

    [SOLVED] Buffer output to microcontroller input

    Hi, Ha ha ha, that's correct with your last Example @KlausST. I just want to protect I/O pins from high voltage and current from external peripherals. According to you my given circuit is correct without serious resistor?

    [SOLVED] Buffer output to microcontroller input

    Hi, I'm using Inductive Sensor-M12. Please explain above quote briefly. In datasheet they mentioned "Maximum output current sunk by PORTA<5:0> and any PORTF, PORTG and PORTH I/O pins- 2mA" In my understand sink current means allowable current by device pins. Is this correct or not? I adding...

    [SOLVED] Buffer output to microcontroller input

    Hi, I want to interface sensors to pic micro-controller(PIC18F87K22). For protection buffer(74HC541) is used in between them. Sink current of PORTH pins are 2mA. Other ports are dedicated to various operation. Buffer output current is +/- 35mA. Is this is a problem? Resistor connected to...

    Detecting solenoid ON and OFF state

    Hi, Actually input_1 is a HIGH or LOW signal from micro-controller using decoding technique. At some situation solenoid may not work like you(@KlausST) said. Using XOR gate I comparing signal from micro-controller and solenoid state. XOR gate will produce HIGH o/p if inputs are in different state.
