      I have bought L293D ic. But, It’s not attached on a pcb. It’s separate ic. Is it ok? Its not looking like you.

      In 5v regulating circuit, which capacitors should I use? Somewhere you have written 10uf and 100uf, whereas somewhere you have written 0.1uf. I am confused.

      Also, can I use 3 batteries of 4v instead of 12v battery?

      Can you upload clear image of Receiver circuit. Or send it on my email pls.

      1. No problem if it is a separate IC

        Use 100uf for input and 10uf at r output
        Refer the power supply circuit

      Do I need to place VCC in dpdt switch also, or only negative. Because you have not connected VCC in circuit diagram but in switch connection diagram, you have connected.

      1. Vcc is really not required

    In the recieve section HT12D should be used in circuit. But it’s written HT12E with pin labelling as that of HT12E but I think the connection is correct with respect to pin numbers of HT12D. Please correct the error

    hi there do i need to replace my l293d because only one channel is working or is there a solution for it?

    Like

    1. If you are sure that one channel is not working then you need to replace the motor driver

      Double check all the connection, and also check both the Enable pins

    I have almost completed the car but recently faced a problem:
    When I press A, the motor turns but when I release the button, the motor doesn’t stop and the connection led also turns off. I have read on internet. It may be due to noise produced by motor. But I need a professional answer from you. What can I do?

    hi bro
    which one i have to use
    HT12E encoder
    HT12d decoder
    is it HT12E encoder or HT12D encoder

    Like

    1. Both are required
      Ht12d is for receiver circuit and ht12e is for transmitter circuit

    “”””For debugging the decoder and encoder IC connect pin 7 of HT12E to pin 14 of HT12D ,Connect push buttons at pin 10,11,12,13 of HT12E and connect 4 leds at pin 10,11,12,13 of the decoder”””””
    BUT IN THE DEBUGGING CIRCUIT YOU DIDN’T CONNECT ANY PIN OF THIS STYLE
