This is a project based on Arduino board which can measureresistance, diode, continuity[H1] , voltage,[H2]current[H3] , power[H4] , hfe[H5] and capacitance[H6] .The values are displayed onthe 16*2 LCD. I want to study more about your project. The optical design will be the most difficult part, but I think I found a solution for this. // Arduino MultiMeter. i will try to make a multimeter and i wanted to know if arduino is the best way/easy way for a begginer . AT+RESET reset AT+SHOW1 show Bluetooth name in response, To connect to the Owon B35T type AT+CONE0 (Mac adress of the multimeter), These softwares can be found on GitHub: https://github.com/awall9999/Arduino-Glass, Here you can see, how all the parts fit in the enclosure. Yes, but these values are calculated/optimised for the voltage range of a 12volt car battery. The best working lens is an Acrylic Plano convex lens with a focal point of 100mm. Follow the project logs to see the updates. I'm an electrical engineering student. The protocol is compatible with the voltcraft-vc820 like seen in sigrok and QtDMM and sadly not simply ascii. Circuit Connection Description of Arduino Capacitance Meter: The purpose of using LCD is to display the value of capacitor. takes power from arduino board. The 162 LCD screen (2 rows and 16 columns) is used to display the values of frequency and period of the input voltage where: RS > Arduino digital pin 2. You can use any other transistor, just check out its pinout and datasheet to make sure that it can be used with the rating needed for this project. First we need to separate 4 wires from the cable, and cut them to a length equal to the depth of the container in which the liquid level is to be monitored. In this case the reference Voltage would be the supply Voltage of the Arduino or 5 Volts. Upload this code to the Arduino: #include <LiquidCrystal.h> LiquidCrystal lcd (12, 11, 5, 4, 3, 2); const byte pulsePin = 8; const unsigned long resistance = 10000; volatile boolean . Parts needed. and they should be perfect. Adding DC current sensor. The focal length is about 110mm, with should be fine. Learn More.

The smart insole collects foot pressure data in real-time. Figure 2. Testing with a smaller 0.49 inch display. my mail is minhc613@gmail.com. First the happy news: my electricity meter has serial port providing live data such as current power, then the sad news: the device isn't in my flat but in the basement, where there's neither an AC plug nor WLAN signal. The new displays just arrived. 3. Hand Gesture Controlled Robot using Arduino, Portable Ultrasonic Range Meter -arduino mini project, Android Smartphone Controlled Power Outlet Using Arduino. Hello there, I'm working on a small project to monitor my electricity consumption at home. The charging current is now reduced to +- 200mA. Step 6: Connecting the Owon B35T Multimeter with the Glasses. because sending over LORA is nice and the MC already has a display soldered directly onto the board. good morning sir! Explore 2 projects tagged with 'multimeter'. Hey, I wanted to inform you I built something like that, well, I did more of a POC. 09/24/2016 at 21:03, Standard Tesselated Geometry - Will build a smaller version. you will get an i=-27.03cm (virtual images have always a negative value) and a magnification M=3.7, Lens calculation website: http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/image4.html, I know that the lens is hard to find. One thing is clear, you cannot just place a screen in front of your eyes, because it will not be possible for them to focus it. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam. Trying to build a cheap Arduino Data Glasses for everybody. They are used in measurement of both AC and DC voltages. and last updated 9 months ago. The project is more about how to build the optical system for this HMD. Breadboard. I hope somebody will read this and take the idea a step further: directly coating the eyepieces of the glasses ( the "glass" of the "glasses" kinda LOL ). I soldered a normal resistor with the value of 5.6k in place to reduce the charging current to 200mA. Save my name, email, and website in this browser for the next time I comment. Am I allowed to do. I'm really feeling pissed off, when I see people using my designs and try to sell them as their idea. I used a microcontroller like this: https://www.amazon.de/Dual-Core-Bluetooth-868-915MHz-Development-Arduino/dp/B078M74NNN. In order to read voltage, I used a voltage Divider to increase the range of test voltage, and I used another function to find the Supply Voltage of the Arduino using the 1.1 Volt Internal Reference of the Arduino. In this project, you will be building a voltmeter and ohmmeter using the digitalRead function of an Arduino.You will be able to get a reading almost every millisecond, much more precise than a typical multimeter.. The shield can be inserted on "Arduino" UNO und Duemilanove boards. am use Arduino again I need to think about remote monitoring because Arduino boards don't having inbuilt Wi-Fi option . A Voltmeter or a Voltage Meter is a measuring instrument that is used for measuring voltage or potential difference between two points in a circuit. A programmable and highly maneuverable robotic cat for STEM education and AI-enhanced services. The lens was a tricky thing. when am working on solar project which charging battery from an solar I need to monitor the current an voltage going to battery, but I can not put an multimeter all time and watch the data and analyze it from remote area. Multimeter. The concept behind this project is to show how a simple analog voltmeter can be built using an Arduino, several littleBits electronic modules, LabView, and LINX software packages. The code is pasted bellow. thank you! (This serves no real purpose, its just a bit of fun). Active multi-beam sonar for robots and visualization on the cheap. 2. , pls reply me soon. 62.58 kB - Hi Mr EMRE, any chance you could email me the code to this project? // (I havn't commented on any of the code, but i've explained the wiring bellow. The costs of the prototype amounted to 70Euros. It is very useful to have jumper wires with alligator clips to make the connection of the motor to the battery easy. . Are you sure you want to remove yourself as The structure of this project is very basic as all the functionality is implemented in the library.The project initializes the DMMShield library (in the setup function of the Arduino sketch) and calls the command interpreter (in the loop function of the Arduino sketch). Make a solar tracker using an Arduino and a 3D printer. Functions of this multimeter are based on an Arduino microcontroller. I just used a smaller battery in the final version. Now, here is the real information: You must have noticed problems with the lens and the mirror. The programming part of this LC Meter project is very easy. Full Arduino code for measuring the DC voltage is given in the Code part below. 8 Pins out of 16 pins are for data communication. Not a member? I made the data glasses work, but it was more a trial an error challenge. To use the 280mA battery, I had to change the 3k resistor against a 5.6k resistor on the original board. A DIY Arduino idea. Display for Multimeter, Active Linear Multi Element Sonar Array (ALMESA), Finishing the Software, to auto connect to a Owon Multimeter. I needed to change the LiPo batteries. Bonus: charge your phone with free clean energy! thank you! jesmalcolm is on Arduino Project Hub. multimeter. I have an arduino . I use now a smaller, 280mA, instead of the 330mA. (Im using an arduino UNO with this project.). Features : For better resolution 16-bit output (two PWM output pin used) Distortion and noise free output.

Complete Arduino code is given at the end of this article. wiring. Now you can adjust the reflection screen, to get the best view.In the next few days I'll test the electronic with the new LiPo, but I'm still waiting for the lenses. It's then reflected over the mirror, goes through the lens and you can see the picture in the little transparent acrylic glass. From the first idea to the working prototype, it took 4 months. And you can cut them with a cutter. The optical design was the most difficult part, but I think I found a solution for this. The multimeter is designed with analog meters or liquid crystal displays (LCDs) for displaying voltage, current, and resistance electric circuits values. (Its pretty self explanitory).
