Air Pressure Sensor / Breath Controller / Arduino Nano

This is a re-visit of the air pressure sensor video using the HX710B chip.
An AVR Nano will be interfaced to the sensor running Interactive Arduino, a Forth operating system. The video will describe the steps to program a .hex file into the ATmega328p and how to compile code using Tera-Term. A demo on how to detect liquids levels will be shown.

You repeatedly saying your glass is half full just made me optimistically happy 😁

[@ShellacScrubber]

Definitely my favourite channel for Forth content and useful circuits ! Thanks for another great video Ken.

[@0033mer]

You're welcome. Thanks for the visit!

[@ohmedarick1]

Thank you for sharing your knowledge and doing on an nano board. Greatly appreciated.

[@shawnlowe1392]

I had no idea you could program a Arduino with forth. Thanks for this video!

[@0033mer]

Check out the description box for documentation and links to other instructional videos.

[@retireeelectronics2649]

Interesting, I guess it is time for me to learn to program again. Good to see someone else uses BC Robotics as a parts source.

[@0033mer]

BC Robotics is my goto place. It is local for me and I like their $2 light packet shipping. Universal-solder and PCBoard.ca is also on my list. I like to support the local guys.

[@JacobKinsley]

1:39 the way you said that made me laugh for some reason, it reminded me of kermit

[@0033mer]

A laugh is good! I have always identified myself as Grover.

[@seanxu1859]

Can the sensor read value if I don’t let the tube interact with water, i wanna attach this to a closed chamber, will it read values if I increase the pressure in the chamber

[@lasersbee]

Another Great followup...

[@0033mer]

Thanks again!

[@galmuxsh8190]

Thank you very much for the video. My question is, can blood pressure be measured with this module?

[@raflimustafidkurniawan231]

Thank you for the information, so the MD-PS002 sensor is not suitable for use as a TPMS? I'm working on my final project and plan to use this sensor because it's low cost, but do you have any suggestions for other pressure sensors that can be applied to TPMS besides MD-PS002 and MPX?

[@deveandiaz9371]

Thanks for de video!! Can the sensor still work with any stored gas?

[@W1RMD]

Thanks for this great video! So is the glass half empty or half full? Best regards.

[@0033mer]

Both?

Awesome as always, thank you for your dedication to promote and explain Forth. BTW, have your real ese the IA code? Cheers!

[@0033mer]

Check the description box where you can download IA.hex together with documentation and links to other informational videos.

[@shawnlowe1392]

Okay, Ive been playing with IA, and I was wondering how I would show that various commands? Example would be the forth breakdown of .pins? Thanks again, I find your videos very inspirational

[@0033mer]

The words added to the original eForth are witten in assembler and Forth so it would be hard to describe. I have links to two videos and a .pdf in the description box for more info on the code commands. IA is a simple Forth for simple projects to get it up and running quickly. The next step would be Flashforth and Mecrisp. I have written some utilities that might interest you if you want to continue with IA. I have no idea on how many people are using IA so I don't know how far to go with it. Thanks for the feedback.

[@serdarsabancilar752]

Hello, thanks for video but i have one question. can we use with normaly arduino ide ? you programmed it a different way

[@0033mer]

I do not use the Arduino IDE for programming but you can. Using the Arduino IDE, send 24 clock pulses to the sensor clock input and receive the 24 bits coming back via the Dout pin for your pressure value.

[@serdarsabancilar752]

@@0033mer thanks for kindly reply, i will try tomorrow

[@gurdog7731]

@@serdarsabancilar752I know it’s been a while but did u end up getting it to work?

[@perryscopevids]

Does anyone know if this air pressure sensor can detect negative pressure? ( or if not a similar one that can) I'm looking to make a (suck/blow) interface for a person with MND but need a way to detect two distinct inputs. From the readings shown would a value of around 0 actually require suction assuming around sea level air pressure?

[@0033mer]

For a Sip/Puff detector you can use this sensor: www.adafruit.com/product/3965

[@winzero7]

That good video. Can you measure vacuum with that sensor?

[@0033mer]

No ... For that feature check out the MPRLS family of pressure sensors. www.adafruit.com/product/3965

[@PaulConnor]

Could the air sensor be linked to a Bluetooth module for output?

[@0033mer]

Yes..you can sent the data using a HC-06 Bluetooth module to your smartphone. kzbin.info/www/bejne/lWbKZp95YtN3r5o

[@haonamtran8061]

How can i use this to estimate water pressure please

[@pproductions9172]

Is this sensor compatible with a raspberry pi pico?

[@0033mer]

You can use any microcontroller that has GPIO.

[@pproductions9172]

@@0033mer Great! Thank you for your reply. Do you know of any resources that would help me write that code?

[@0033mer]

For the raspberry pi pico you could use Micropython with many videos available online. I program using the Forth programming language. Check out this video: kzbin.info/www/bejne/l4jCf5tshsaBiZI

You're welcome!

[@yusufmujeeb9693]

Can you supply code of this sensor with a pic microcontroller

[@kepamurray1845]

I know you are passionate about your Forth programming. You would have exponentially more subscribers if you were using the Arduino IDE though. Thanks anyway.

[@ShellacScrubber]

What a bizarre comment !! It would be like saying to Jon Anderson of the band "Yes" : "Jon, if only you sang pop instead of prog' , you'd have exponentially more fans !!!

[@0033mer]

Thanks for the feedback. There are many channels on KZbin that use the Arduino IDE so that is pretty well covered. My main goal is to make people aware of Forth and how it is used, so I am not doing it to acheive many subscribers. Forth is still being used today in complex projects but is never advertised probably for security reasons. Look at cryptocurrency where BItcoin uses blockchains to record transactions that is secure and cannot be altered. A Script is used when a transaction is made and that Script is written in Forth. Check out this link: en.bitcoin.it/wiki/Script

[@marswatcher]

Arduino users would be exponentially more productive if they used Forth!

[@kermets]

great video, Have you seen a similar air sensor I could use on my turbo car maybe with a range of 5-15 psi cheers Brett

Yes.. Here is a link to Adafruit's pressure sensor: www.adafruit.com/product/3965

Please just use C++

OMG. Thank you very much. I am looking for that set 2 years. Thank you for that hope you give me. I need to mix Arduino ide with your code. But your code is in an other format. Can please make a code in Arduino ide

[@0033mer]

I don't use the Arduino IDE, but if you look at my code and explanation on how it works, you can write similar code using the Arduino IDE.

[@gurdog7731]

I know it’s been a bit but have u figured it out?

[@abdulrahmansaeed4598]

Do you have code for Arduino IDE instead of hex code?
