Using MAX6675 Thermocouple with ESP32 Bluetooth

[@neilgrice9251]

Thank you for such an informative lesson. I will be trying this as it suits my needs perfectly.

[@Beekeeping_Bro]

Nice work bro. I have been having an issue to find Schematic( pinout ) to connect ESP32-S3 Wroom to MAX6675 Amplifier with K-type thermocouple. I find Schematic for ESP32 with K-type thermocouple and MAX6675 Amplifier is NOT working for ESP32-S3 Wroom. Do you have any information on this ? please let me know. Thank you for sharing your knowledge and expertise with us.

[@gag_sin_gracia]

Sorry, I'm new to this matter. Can you tell me how many of MAX6675 module can be connected/read at the same time?

[@robojax]

as many pins you can find on the board.

[@manojvc6356]

Very use full video.. thank you.. 😍

[@robojax]

Welcome 😊

[@990LoNeWOLF]

plz explain PCA9685 16 Channel 12 bit PWM Driver with HC-05 blutooth module with code..........

[@robojax]

can you tell me why people use so much this HC-05? there are latest HC-06 and now HC-09

[@MrBrymstond]

Is there a way to do inside temp as well as outside with a different component maybe? Or do we need to make two?

[@robojax]

this sensor can measure only ONE area.

[@rv6864]

I trying to modify this sketch to have it loop continuously updating temp without using the smartphone buttons? Thankyou!

Great video thanks

[@robojax]

Glad you enjoyed it

[@jenslyn42]

if (receivedChar == ' ') is interpreted on your website as an actual line break, so when you copy the code it is invalid and no idea what the char should be, I only figured it out by stratigically pausing your video many times till I caught the same place in the code

[@robojax]

You are right. There should be a Download link , if not I will post the file for downloading

[@andrewsol5850]

Than you! Keep going!

[@robojax]

Thank you too!

[@neilgrice9251]

Having difficulty using IOS. I have downloaded a Bluetooth App for IOS (BLE Scanner 4.0). Changed the rate to 115200 it complies but will not upload due to "esptool.py v3.0-dev Serial port /dev/cu.Bluetooth-Incoming-Port Connecting........_____....._____....._____.....__" Error. Port selected as, "/dev/cu.Bluetooth-incoming port" Any thoughts out there?

[@lexmartin663]

where is the BluetoothSerial library, I don´t find this

[@lexmartin663]

no funciona amigo

[@robojax]

Heave you resolved the issue?

[@Evilslayer73]

It can be cool to build a bluetooth control soldering station :)

[@jhoanstevencastrorojas6608]

i couldnt find the code in the link you left, could u help me please?

[@robojax]

You made me watch the video making sure I did not forget to mention it. Indeed I have mentioned it in the first 30 seconds of the video..

[@vtbn53]

@@robojax No, the code is DEFINITELY not there unless you have called it something NOT including the terms esp32, bluetooth, thermocouple, or MAX6675.

[@PackPlTV]

I have to agree there isn’t the code

[@vtbn53]

@@PackPlTV It's amazing isn't it? And he still hasn't corrected it.

[@MrBrymstond]

Can we also do this with WiFi for extra distance?

[@robojax]

I have the wiFi version. check it. You could edit your comment to just post one comment snipboard.io/eawCtO.jpg

[@vtbn53]

@@robojax That's for a different module though, is the code compatible with ESP32

[@rv6864]

I'm getting errors with line 10 After the void loop function. if (receivedChar == ' ') Received char cannot be used as a function Could someone help? Thanks!

[@edwindaniel6956]

while (SerialBT.available() ) { receivedChar =(char)SerialBT.read(); inData += receivedChar; if (receivedChar == ' ' )

[@robojax]

The life with “if” might be broken. Move the “ ‘) “ to the same line and try

Has anyone found the code for this? Thanks

[@robojax]

The link for the code is under the video in description. Beside I have shown the website name Robojax.com multiple times. Just got there is get it.

[@chrisvild1263]

@@robojax thanks... i must be missing something. Do I need to cut and past the code or is there a INO file.. Thanks

[@robojax]

What you use it combinations of two device . The links are in description. Watch two videos before coming to this

Всё это игрушки Надо хотя сделать три Температурные полки чтобы работали через таймер

[@sola9649]

there is no example for the Bluetooth sketch

[@robojax]

Then what is this? Sketch in Arduino means code which I have provided

[@filipegomesdesouza6754]

Hi, very useful video!! awesome. is it possible to use more than one Max6675 with ESP32? I need to use 6 sensors to be more especific.

[@robojax]

search my channel for it.

[@filipe5660]

@@robojax thank you for answering !!!😎 I didn't find anything on this matter with esp32 inthe channel, only with arduino. is it possible do the same with esp32?

[@robojax]

just use the same code available for Arduino. it will work ESP32 and ESP8266

[@robojax]

Here I have written code for you to use 2 or more K-type sensor with ESP32. I have not tested it so you have pay attention and study each line and I am sure if you watched this video, you will learn a lot. robojax.com/learn/arduino/?vid=robojax_ESP32_MAX6675_multiple good luck and please understand that that is the best I could not. this is just guide for you. I have no time to check the code or test it.

[@robojax]

You didn’t even bother to reply? I spend time for you to help you. Wow

[@MrBrymstond]

A single 18650 can power this.

[@robojax]

I believe I've shown the voltage and how to connect it. See it in video. snipboard.io/eawCtO.jpg
