  1. Closed: Re: Help wiring a Ne555 Timer delay module (monostable?)

    if you want the module to have a trigger input in monostable operation ,
    trace the circuit in the board and modify it.
  2. Closed: Re: Help wiring a Ne555 Timer delay module (monostable?)

    The board does not have the option of separate trigger.
    Switching ON of pwr supply generates the trigger internally.
  3. Closed: Re: Help wiring a Ne555 Timer delay module (monostable?)

    The board is not a faulty one. It may bes on the wiring diagram given.

    Make an experiment . Just Connect Vcc and Gnd terminal to power supply .Dont connect any other load or switch.

  5. Closed: Re: Ethernet software or terminal in windows for ZYNQ

    Teraterm can be used for both uart and ethernet.

    telenet is the mode.

    yes. you must have telenet service on bothends.

  7. Closed: Re: Ethernet software or terminal in windows for ZYNQ

    telnet can store the recd data in file.
    ZYNQ is the server and windows PC is client.
    the trasferred data should be in file format .

    if your ZYNQ cannot meet this then telnet cannot do it.
  8. Closed: Re: Ethernet software or terminal in windows for ZYNQ

    windows contains a command 'telnet' or you can try

    Welcome to the edaboard!

    Coming to your idea ,
    since you want the motor to rotate slowly a geared Dc motor will suit your requirement. (other motors like stepper , servo etc can be used but with...

    Closed: Re: Synchronize comparator output with a clock

    whatabout a clocked D-FF with D input from comparator out and clock from your source?
  12. Closed: Re: First 555 timer circuit, bunch of questions using a relay

    not advisable to keep trigger pin open(pin 2) .
    connect a 10k resistor to supply Vcc and pin 2 . then pin2 with a push button switch to ground.

    otherwise the behaviour will be random.
  13. Closed: Re: How to convert accelerometer data into G with the ADXL345 digital accelerometer

    Nothing wrong.
    it indicates that the accelerometer may be stationary but is not perfectly vertical.
  14. Closed: Re: How to convert accelerometer data into G with the ADXL345 digital accelerometer

    in the +/- 2g range , the resolution is 10bits.
    The value per bit is 3.9mg.(3.90625mg exactly).

    multiply your axis reading with this constant to get g value.
  15. Closed: Re: How to determine voltage level on Pin 2 of the comparator

    the current flowing through 0.22 ohm produces a drop which is compared with the Vref you set with R2 pot.

  24. Closed: Re: MC1306 vs lm386 which one has more gain can you please tell me?

    datasheets wise , 1306 is capable of more gain compared to lm386.
    actual gain of the circuit is dependent on the circuit you have wired.
