    Decoding 433.92mhz remote?

    Yes you may cause the protection diodes on the transmitter to switch in and cause latch-up this is a bad thing. Always switch with correct levels for the particular device. Adam

    Decoding 433.92mhz remote?

    You need to reduce the voltage then. The Arduino puts out 5 Volts and it looks like the transmitter runs from 3.6 volts. It just so happens that 5-3.6 = 1.4 so two silicon diodes in series from the arduino port might be all you need. You will need to duplicate this for each button obviously. I...

    Decoding 433.92mhz remote?

    What battery does the unit run from? The Vcc might just be powering the IC and not the rest of the circuit. If it runs from one of those small 12V batteries then fit the battery but leave the 0V (GND)wire connected. How are you picking up the data packet? The IC might run of a different voltage...

    Give it a try. Adam

    require help in wave theory

    Do you think a wave is like a metal wire that we can use to transport particles along to where we want them to go? Adam

    Yes an oscilloscope. Adam

    I am more attracted to a nice Sziklai pair than a woman. :) Adam

    Yep, I didn't like to say :)

    Decoding 433.92mhz remote?

    Something that might work if you don't have an Oscilloscope is to try and make a data logger using the arduino. Two options I would try is to sample the digital data coming in very quickly and log this to memory or maybe output this to hyper terminal or something like that. Then you could work...

    Decoding 433.92mhz remote?

    Can you post some close up clear pictures of the transmitter so we can try and identify it. Thanks Adam

    HELP needed with part identification PLEASE

    Could be Steve, but the lot number seems to be in a different place. There is no reference to 1S. Thanks Adam

    Nano no longer working

    I can confirm the above post is correct. After getting the device replaced it now communicates with the PC and I can now programme the device. The next step is to get the code to run. I contacted the seller in China, Jackie Chan was his name I think :) And after asking him where he wanted me...

    ultrasonic leak detector

    Even if they don't go anywhere they need soldering. There might be a common or supply connection needed to stop the pins floating this connection might be under the IC and you can't see them. The 4069 is being used as the oscillator for the circuit I am pretty sure of that. Adam

    ultrasonic leak detector

    I bet you thought I was crazy didn't you! LOL. Good so it might just be a damaged transmitter. Adam

    Nano no longer working

    Ok get this, I ordered two Nano's from different people. One came in a kit with lots of other bits and the other was suppose to be a genuine Nano from Arduino. Both now bricked, both PID codes 0. Both parts had the same batch code, funny that!. If your Nano has batch code CN480661 then it's...

    Nano no longer working

    Great news this could be my problem also. I have a sainsmart Nano that worked once and now I can't upload anything to the Nano using the IDE via FTDI USB. I can reprogram the boot loader using the USB ISP but if I upload a sketch this way the green LED goes out and nothing happens. Adam
