      what grate kit... good for tones of application with a serial connection..
      20amp is a good choice
      i would make it a hybrid to turn it on and off like lower the clock speed....and turn off monitor...so when you need to do a serial check crank the clock speed an read....
      question
      can you 90v dc reads or just 30v?
      can you do AC herts check like is it 50 or 60 herts....
      grate reusable modular addon for any project.....
      with all the code what a bonus

    Nice project. I tool a look into your code
    You consume many cycles inside the loop() method to identify the mode.
    if( mode == 1 ) then... if( mode == 2 ) then... if( mode == 3 ) etc..
    This project has to move to C++ and make a class object with inheritance
    It can be super fast and probably can add more features later using the Uno.

    Essential thoughts for the version 2.1. Make sure that the 4 mm banana sockest are 19.05 mm (0.75 inches) apart - this is the world wide standard for test gear. Include a 2x3 pin header location for ISP, this is very standard for Arduino-like boards. Consider tracking and pads for some sort of input protection. (And don't forget to get the display connector the right way round.)

    Nice work.
    Two more ideas you could add, multi-channel voltmeter and square signal generator. Sometimes it is useful to see voltage on different points on a one screen. I do it by using analog pins, but you can implement multiplexer.
    And max and minimum level buzzer, if current, voltage gets to high or low.

    Very cool, looks sweet, except of the housing and that the switch is sticking out.
    Your single tutorials about the single measurements are very helpful, especially for beginners, like usual for you and this is a sweet project that I would love to see improved, in first place use a different display, what it needs is a big good readable display, no one needs colors on a mouse-tv for this jobs, use one of those 12864 COG displays, with an UC1701 driver or something compatible, there are libraries for them aswell, they cost around 4€ and are the best right before the pcd8544/Nokia 3310 lcd's by the price-performance ration, have big pixels and are very nice to read, I am short-sighted but don't need glases for this even if it's a good distance away.
    I want to build a propper multimeter, I mean a multi-meter, so a combination of a LCR-/Transistortester, multimeter and basic oscilloscope, maybe something else like a function generator, but stuck on the LCR-part, wish there would be an open-source code for the Transistortester from mikrocontroller.net, because I have no idea how to make the automatic-detection. I also want to use relays and pre-measurements, a protection through an op-amp or maybe something smarter, to make sure nothing will happen, if this, the connectors or cables burn it is bad enough, but I don't want to burn the whole circuit in case something happens, I never burned any multimeter or something like that, but this can happen any time to anyone, sure, it will make the measurement slow, but also gives the possibility to auto-range even the voltage. It will be not that small and I have a design in mind so it can be used as a desktop multimeter like as a mobile one.
    But something like that is a lot of work and I would completely understand if you wouldn't want to make it open-source, I'm not sure if I would, if I get it done one day, because only the osci code is a propper book by the size.

  • @fd3871
    @fd3871 4 года назад

    the acs712 has a slow sensitivity isn't reliable with that adc. that adc has an internal voltage reference and since the acs is ratiometric, small changes in the supply current will effect the output of the acs while not affecting the adc. With ratiometric sensors, it is best to use an adc that accepts an external voltage reference or uses the supply voltage as the reference voltage (like the mcp3221), and then to power the acs and adc with that voltage reference. an alternative, would be to use a non-ratiometric sensor like the acs70331 which I've found to be more accurate than the acs712, acs723, .etc. when measuring currents

    This was a very neat project. I was very excited to see that bluetooth connection and listen to your thoughts on sending the data to a smart phone. With the Bluetooth Serial Monitor app you wouldn't even need a custom app.
    I wonder how difficult it would be to have a data logging feature with an SD card or to have data logging on your PC. I do not know if a PC could data log from the bluetooth connection.
    I see that the maximum voltage is 30 V DC. Using an external voltage divider circuit to step down the voltage and then calculate the real voltage is one way to increase this range. I'm wondering if there is some kind of probe that can be built that can be plugged in to step down the voltage sort of what goes into oscilloscopes.
    Thank you for sharing.

    Firstly i'm not a electrician if i wrote something wrong please correct me.
    By reading acs datasheet there are only 5,20,30 amp versions.
    I don't think that slide switch for current measurement will handle more than 0.5A and probably pcb tracks too. For programing pins why you use pads instead holes like in serial communication port it would by much easier to programm.
    And lastly adding up all component cost that you listed it is around 70 USD + PCB + soldering time, for that you can get "realy good" multimeters. You have a lot of realy interesting project on your channel but this one...

    #Project #Request
    Plz plz Make arduino based #Rf
    #Spectrum Analyser range from Mhz to 2 ghz using rf modules like sl4432 , hc12 , Nrf24L01 , RDA5807M fm tuner. etc
    With feature of -
    Arduino Usb serial interface for better viewing resolution and better UI control using some open source spectrum analyser software .
    Also With Nokia graphic display attached with circuit for operability
    .it would be better if it would have Bluetooth included with this project because one can built related app (may be you ) using Mit Ai 2 App making Tool.
    That will be great project because spectrum very great tool when we are dealing with rf Radio frequency or making smps .

    The pcb is bigger than you need. It could go smaller as the display dont have larger digits. I like the idea but dont like your pcb design, though I appreciate your affort for this prototype

      Louis Scully has designed and built a couple of different function generators that you may find interesting: ruclips.net/video/ZCdTxRASqiQ/видео.html. He also has a web site where he's documented the project: www.scullcom.uk/function-generator-mk2/. His videos have very good detail about why he made the design decisions he did, which I've always found very interesting. He also has several other similar projects - voltage calibrators, electronic loads, etc.

    hey @Electronoobs i am Vaper and i want to build myself a Ohm-Meter for my Coils. I have the Problem, to measure Resistance as low as 0,05 Ohm till maybe 3 Ohm.
    How to archive that? i did not find anything usefull, how to to that using a MCU .

    • @ELECTRONOOBS
      @ELECTRONOOBS  4 года назад

      Well you could buy a very precise multimeter, you could use the ADC1115 16 bit and measure the voltage drop on that, you could apply 5V for example and measure current and by the formula I=V/R get the R...

      @@ELECTRONOOBS i dont want to buy a precise Ohmmeter because of the hugh Costs.
      that may not be usefull, because such a Coil draws everything from the 5v Source.
      with one 18650 Cell it draw @ 0,12 Ohms about 31A..
      maybe it is better with a Constant-Current Source to measure the voltage drop on the coil?
      i am not sure what Test-Current i have to apply and the Calculations ... it has to be somewhere in the 10th mV ?!
