## Hi, im trying to run my coding using mpu6050. Failed to find MPU6050 chip. Can someone help me? '/\*

Library Used:
              1. SparkFun MAX3010x Pulse and Proximity Sensor Library by SparkFun Electronics
              2. Adafruit MPU6050 by Adafruit
              3. Firebase Arduino Client Library for ESP8266 and ESP32 by Mobizt
              4. Firebase Client by Mobizt

Safe Changes:
1. WIFI & Password
              #define WIFI_SSID "Xiaomi14" // WiFi name
              #define WIFI_PASSWORD "takdapassword1" // WiFi password

2. Upload Interval - changing this to less than 5 sec = will upload in less 
   than 5 sec & the fall detection has a period less than 5 sec to check.
              const unsigned long uploadInterval = 5000; // 5000 = 5 Seconds

3. Led to Buzzer

    For the sake of sanity, buzzer is set to pin 2
    which is the built-in led pin.
    
    You can also plug buzzer at pin 2 without changing the code.
    If you do decide to check, please change it here.

    #define LED_PIN 2

Welcome to the forum

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'  
  
Use **code tags** (the \< CODE/ \> icon above the compose window)&nbsp;to make it easier to read and copy for examination

> [@How to get the best out of this forum](https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum/679966):

> See also [FAQ - Arduino Forum](https://forum.arduino.cc/faq) for general rules on forum behavior and etiquette. Hello, Welcome to the Arduino Forum. This guide explains how to get the best out of this forum. Please read and follow the instructions below. Being new here you might think this is having rules for the sake of rules, but that is not the case. If you don’t follow the guidelines all that happens is there is a long exchange of posts while we try to get you to tell us what we need in order to help you, which is frus…

Posting your code using code tags prevents parts of it being interpreted as HTML coding and makes it easier to copy for examination

In my experience the easiest way to tidy up the code and add the code tags is as follows

Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.

It is also helpful to post full error messages in code tags as it makes it easier to scroll through them and copy them for examination

What is the exact ESP32 you are using? SPI and I2C Pins vary a lot.

What is the serial printout from the setup sequence?

Does the other SPO2 sensor work?

How did you wired everything up?

What does the AI said, which wrote the code for you?

Hi, @adibzikri  
Welcome to the forum.

What is your electronics, programming, arduino, hardware experience?

Have you tried the example code that comes with the MPU6050 Library.

That looks like a lot of code to find this problem, did you write it yourself?  
Did you write it in stages, testing each stage as you went?

Who is,

Can you please post a copy of your circuit, a picture of a hand drawn circuit in jpg, png?  
Hand drawn and photographed is perfectly acceptable.  
Please include ALL hardware, power supplies, component names and pin labels.

Thanks.. Tom.... 😃 👍 ☕ 🇦🇺

Maybe you also want to remove the credentials/keys etc. from your post.  
You may need the help of a moderator to delete these from the earlier version of your post which will be created once you make the changes.

There is also a similar thread here which may give some trouble shooting tips: [ESP32 not finding MPU6050 Gyroscope](https://forum.arduino.cc/t/esp32-not-finding-mpu6050-gyroscope/1411389)

The C3 Supermini has two different pinouts going around in the wild.

> Hi everybody, I am not too much familiar with HW stuff and a little more than newbi on SW. I would like to use this ESP32C3 supermini board. For the pinout I found some different versions on the web and I wonder which one is the real one? My second question is: I want to use just 3 simple digital output signals to drive stepper motors, 5 digital inputs for switches and pulse buttons and the SDA/SCL pins for an I2C-Oled Display. Do all GPIO-pins provide this sim…

So maybe check if SDA = 8 and SCL = 9 works or SDA = 8 und SCL = 7.

Then try the ideas from the other posts. Reduce the code to the bare minimum or use a demo script to check the functionality.

I would suggest you start small, proving out pieces of code.

I usually start with a sensor, running the library example code. If that works move on to the next piece of hardware.
