ADS1115 16 Bit ADC Module with Arduino

[@chesshooligan1282]

This is my first video in this channel, immediate subscription. No annoying intros, no rambling, no waffle, no "He-llo... this... is... the... guy... with... the... Swiss... accent..." Straight to the point and fast-paced, but not too fast. Schematic, code examples, and links in the description. Absolutely perfect. I wish all KZbin videos were like this. Thanks.

[@aliens1192]

Very nice description and comparison between those little buddies! Thanks, man!

[@erikderuiter7475]

very useful information and as a relative electronics novice I can follow this very well. I want to built an Arduino multi input voltmeter to experiment and learn electronic by probing several points in the schematic simultaneously so this little chip is very useful! I'll have to look into the impedance of the chip but it looks promising. Thank you!

[@TheDefpom]

The arduino can have a different (lower) ADC reference voltage applied to give finer measurements, BUT you are limited to that voltage as the maximum input level on the analog inputs.

[@markhall3323]

Very useful and well-made thanks

[@electronic7979]

Helpful information. I like it.👍

[@markuspfaff5504]

great Video an your other projects :-) have a simple question: if I need no +/- range, but a range from 0V to 2,5V with the best resolution of the ADS1115. I dont know, I have to programm this effect. 0V to 2,5V shout be a digital value 0 to 65536. Is that possible?

[@gianlucamolinari3490]

Could someone help me to properly connect a load cell to the Ads1115 for Arduino uno? I can't find the proper wiring with a load cell anywhere. Help would be greatly appreciated

[@josephcoyne5083]

I have a question for you. So I wired everything exactly the same and used your exact code, but I am having trouble. When I set my gain to 2x gain my resolution I read from the serial monitor on A2 is only 1mV- meaning the smallest value it changes by when I adjust the potentiometer is 1mV (it should be 62.5 micro volts). Also I tried reading the adc2 value directly (not converting to mV) and it only has a resolution of 16 integers (it will jump 16 numbers when I adjust the potentiometer instead of just 1 ) Please help me!! :)

[@aldercamper9430]

only yesterday made a current meter with a current transformer and this chip.

[@whitefields5595]

I am about to do the same. Were you measuring AC? Did you make use of the +ve and -ve values on the waveform?

[@kopileo9857]

Wait, my ADS1115 couldn't read the data output. it just my Arduino A0 can read the data. But when i use SPI scanner, there is an address so my i2c has been connected. but i'm still confuse why it didn't give the data. is there any idea?

[@danielcohen2058]

Thanks for the video. How do you configure the sampling rate?

[@ArjanvanVught]

When using an ADS1115, then we can just use a STM32 family chip as well.

[@GadgetReboot]

I still need to get my first hello world STM32 project up and running. I think I’ll start by blinking two LEDs instead of the usual one.

[@GnuReligion]

When using differential read, can you make a reading beyond the voltage range of the power going into the ADS device? Like between 14V and 15V to get 1V.

[@GadgetReboot]

If we want to use voltages outside the device’s tolerable input, there’s other structures needed like maybe an isolated or floating measurement scheme. I’ve never done it but here’s one article related to that www.maximintegrated.com/en/design/technical-documents/app-notes/1/1108.html

[@hyperrunner4589]

What to do if I want to transmit 16bit data to slave via bluetooth?

[@smsohelrana9515]

If I want to measure 50 to 500 V (Sensor signal) AC via Arduino then how to possible? If I replace the potentiometer and connect the sensor output to ADC. Please let me know connection diagram if possible. Thank you.

[@GadgetReboot]

It's not a simple answer, especially because there could be safety considerations that greatly change the design complexity, and also not knowing the design requirements, a suitable circuit can't be designed. For instance, does the entire signal need to be preserved so it can be analyzed in software or just the maximum/minimum voltages seen over a time frame need to be captured (so a circuit design totally changes and can be simpler) etc. So you'd be better off researching application notes from manufacturers of ADCs to see how they implement various measurement goals, and other power electronics dedicated resources to see how to deal with and interface with hazardous voltage levels to be able to safely and effectively measure them.

[@gkpgeo]

Can we measure voltages above 10 volts with help of ADC thru converter?

[@GadgetReboot]

A voltage divider can scale a voltage down until it's within the input range of the ADC. If the voltage is below 0v it will need to be shifted up somehow and things get more complicated.

[@FlySweden]

Hello, Could I use an Arduino Pro Micro (10bit resolution) with the ADS1115 (16bit resolution) to build a joystick (with better sensivity) that uses some hall effect sensors with magnets ? Thank you !

[@wingandaprayer883]

Yes is the answer, I have just done that very thing with several controls, using the pro-micro hooked up to a ADS1115.

[@luosser]

hello, I want to measure the negative voltage and send it back to arduino due but the datasheet of arduino due says it cannot receive negative voltage, will it make any difference .thank you

[@GadgetReboot]

The ADC chip also can’t directly take a negative voltage other than about 0.3 V below ground. but even if it could, it’s only communicating back to Arduino as a data signal over I2C so the Arduino wouldn’t see a negative voltage itself. if you’re doing a differential measurement where you can actually get negative numbers, it’s still just a subtraction between two different positive analog voltages.

[@luosser]

@@GadgetReboot Thanks for answering my question！

[@ELEKHOB]

Nice video... Need help, I want to single output 0-5volt. I have try use arduino only, but have value 0-1023. Use arduino only and view in plx-daq. I have ads1115 and arduino uno need the wiring and code to get 16 bit and decreet more than use arduino only.

[@jajuliproject]

please mention your code on your screen here ...

[@carlosmf6954]

👌

[@Scrogan]

I think it’s Vref/(2^n - 1), not Vref/(2^n). Because the smallest value will always refer to 0.

[@GadgetReboot]

I always found the topic confusing and this thread tries to straighten out the whole concept of measuring a range of voltages per bit rather than an exact voltage. It’s one of those things where I need a clear mind to go back and try to understand it all again. At least for the things I’m doing it doesn’t affect the results drastically. forum.arduino.cc/index.php?topic=303189.0

[@ashifriady]

because array start from zero

[@apollorobb]

Thats 187.5 microvolts not millivolts
