ADS1115 16 bit ADC with PGA test and measurement

[@abomatar3340]

Thank you very much 😍 with the help of your video I solved the problem that I have been trying to solve for 3 months ❤

[@crocellian2972]

Reading for hours on the ADS1115. Why is it only 2 to 15 on a 16 bit ADC? The sign bit. If you start w/ this video, remember that.

[@JohnClulow]

Thanks so much for this video. I'm just getting into a project using an ads1115 and your video was a super introduction. I'll next look to see if you happened to do one on a differential application.

[@billymartin1921]

Chicago John thank you very much for your encouragement. I'll do one on differential. Good idea.

[@ruzgar_adam]

Thanks, for good explanation

I like to use 90’ pin headers with boards like this so they sit up vertically and don’t cover so much of the space underneath

[@billymartin1921]

That is a great idea! Mark, I am going to use that on my next project. Thanks for sharing. Billy

I am trying to set up an auto ranging measurement system and I was wondering whether it is safe to change the gain of the ads1115 inside the loop in the Arduino code. I want to select the best gain to use given the input voltage for the highest level of precision. The project I am working on is actually an ohm meter. Any suggestions?

[@mr.mythoclast4451]

hey, thanks for your Video. It try to measure realy low resistance Vape Coils with a 100mA constant Current (LM317), but i dont get it ... what do you think is the best way to measure 0.05 - 1 Ohm resistance with a constant current and the ADS1115 ? or maybe i am doing anything wrong in conversion

Hi Billy, Just discovered this wonderful channel, is there any new videos coming up? Thanks, Karl

[@billymartin1921]

Karl Ng , thank you so much for your kind remarks. Yes I do intend to make more. I had family member turn Ill and I suspended making them. I will start very soon making more in my new lab with some upgraded equipment. Thanks again, billy.

Hello : I wanted to comment that I had problems with the module ads1015 when wanting to measure 2 signals in differential mode. I want to clarify that the circuit with ads1115 does not share gnd with circuit that I am measuring (bridge rectifier without capacitor) voltage and current by means of a shunt. When I measure separately, the measurement is correct. When I want to measure both, the measurement is incorrect. I hope you can help me with the problem. Thank you.

Hi Sir, while working with gain 16, the output bits are not stable and affecting my measurement. How to get rid of these digital noise?

[@pulesjet]

Going to play with some tenp sensors from Li Ion battery packs.

[@billymartin1921]

Awsome! Let me know how it turns out.

[@AvishekDasPostdoc]

That's a nice tutorial Sir. Thank you.

[@billymartin1921]

Thank you for your kind words. I am getting back to making videos again very soon. I had to suspend due to a sickness in the family. I have new equipment for the lab I would like to show as well. Billy

[@AvishekDasPostdoc]

Billy Martin.... Oh nice... i am going to make a instrument. i may need your help Sir. How can I contact you?.

[@billymartin1921]

Avishek Das my email is [e-mail]. Write anytime.

[@AvishekDasPostdoc]

Billy Martin ... okay thank you..

[@muhammadshahzaib9122]

Great job, thumbs up. Can you tell me plz, 4.09V will be the AO analog input voltage signal, or it is Vcc input of ADS1115. ?

[@billymartin1921]

Muhammad Shahzaib thank you for watching the video. That is a great adc chip. The 4.096v is the maximum allowed voltage to be input to A0 with the amplifier setting at a gain of one. So you can measure voltages from 0v to 4.096v on A0. If you set the amplifier gain to a different setting then your maximum input voltage on A0 changes. I hope this helps. Thank you. Bill

[@muhammadshahzaib9122]

Billy Martin Thanku so much. i will be using this chip, i will be back soon ☺

[@rekhaphadke5989]

Hi Billy, Can you please mail us the code used here,also the ads115.h and wire.h files ,and how to add them. can you please mail it.Because we are gewtting some errors while running this code.

[@veenakeeranagi6425]

Can you please share the code for single ended ADC1115 programmed with arduino. I am using the code one from githud but it isn't reading anything except 3.3 volt....!!

[@billymartin1921]

veena keeranagi, hello, I would be happy to. I don't have it on github, but I can send it in a text file to you. My email address is "[e-mail]". Send me an email and I'll reply with the code.

[@veenakeeranagi6425]

Hi Martin, Thanks for reverting. I actually got the readings. The github code doesn't give values when we connect the addr pin of ADS1115 to GND, atleast in my case. I changed the connection of address pin to VDD and the code addrss 0x49. The code worked fine. However would like to know if you did anything different. I will mail you on the email provided above. Thanks again.

[@cccyberfamilydk]

Nice video Billy

[@billymartin1921]

Christian Christiansen thank you.

[@crocellian2972]

Great. Thank you. I guess you’ve had good luck with Eata Fruit. Not universal. Please investigate viewers’ experience. Could help us.

[@elChico-TV]

You are videos are good because you use decent hardware to test product but The MAIN issue here is you talk to much and its kind boring showing us how to use calculator instead show us the part of code and explain it. You could write this in comment in arduino sketch and just explain fast and show the measurement because thats why most of your audience came here. You could test adc under different power supply datasheet shows that work from 2v to 5.5v you could test then instead doing calculation 10 min from 20min video. Anyway thanks for this video

[@billymartin1921]

Thank you for your viewership and your constructive comments, I will definitely take them into account.

[@ijustwanttogosailing8248]

True, alot of talk beside the point.
