Already told in video- 3B+

Try to check the blynk library, it’s is recently updated.

Yes. You need to remote the code for IR sensor and add the code for ultrasonic.

Yes you can. But remove the code for ADXL and add for vibration sensor.

Check there may be different IC in your board.

Try to Upload to bin file as per the size of your board.

Replace the code of DHT sensor to MPU sensor and that’s it.

For the com port, install the com port driver. And check it in the device manager. And even after it, not displaying the com port, then there is hardware issue in the board.

Read the code carefully, check what we need to change in the code and try it by yourself. If there is an issue, then let us know.

Replace the code of Adxl with MPU6050. Also change the condition for alert.

What do you mean by change the condition for alert ?

While it sense miss-happening.

@@SMEDehradun when calibrating the GPS with the Arduino I did not get the reults . It does not change after 5 minutes , as you explained in the video. I need help to figure out what the problem is ?

Gps signal is depend on your location. Take it outside from your place and then try.

This is typical method to connect With blynk cloud. You can use below video for smart dustbin. th-cam.com/video/mLzEb_1i9UQ/w-d-xo.html

@@SMEDehradun it is showing the same error again . That no serial data received

Disconnect all the connections and then try. Watch each and every steps of the video carefully. All the required information has been described in it.

You have already asked the question in another video. Check the answer there.

There is no issue of 3 pin or 4 pin ir sensor. Check the connection properly and try.

No. It will upload default bootloader.

Please tell sir quickly I have project in school

I am not getting your point. Can you explain more project if you don’t want to measure level?

I telling you that I have uploaded code but it cannot connect wifi and another proplem is I have no lr module only I have ultrasonic sensor,my project is just automatic dustbin I don't want to check bin level how to do this please tell

​@@SMEDehradunI telling you that I have uploaded code but it cannot connect wifi and another proplem is I have no lr module only I have ultrasonic sensor,my project is just automatic dustbin I don't want to check bin level how to do this please tell

For the wifi, check your wifi and blynk credentials. If you don’t want to use ultrasonic sensor to on off the dustbin flap then you need to edit the code, remove the ir sensor code and level code. And add the code of ultrasonic as per your requirement.

You can connect to Blynk using below alternate method. th-cam.com/video/mLzEb_1i9UQ/w-d-xo.html

@@SMEDehradun sir I have no। Ir sensor and I don't want to measure bin level just only smart dustbin so how to do ?

Yes you can use for water level monitoring.

You need to edit the code for ultrasonic sensor. Below video link guide you how to do it, but you need to remove the dht sensor code and add the code of ultrasonic. th-cam.com/video/c5u6-Th1sI4/w-d-xo.html

@@SMEDehradun ok sir I tried again and connected my mobile hotspot to my laptop and in the code as well now it's working fine touchwood 🙏 Hope it doesn't screw up like last time during my presentation 🤞

Congratulations. Don’t change your hotspot credentials or your Blynk template.

@@SMEDehradun sir I had a query when I am connecting only the nodeMcu and distance sensor the sensor is working fine but when I am connecting my whole circuit with LEDS and buzzer it is not showing distance properly after a few seconds it shows 0 Any idea why is this happening is it because of less power as power is being utilised by leds and buzzer? I am connecting my nodeMcu to laptop and taking power like that

@robo4827 I think this is not due to power issue. It may be due to connectivity issue.

Yes you can. Connect all the voltage pins together. No changes in code.

Can’t help in hardware issue.

Use servo library for ESP32.

@@SMEDehradun I'm using that only but still the same error comes, please help!!

Select the proper board, change wifi and blynk credentials, servo library for your board can help you only. All the information already shown in the video. Plz watch carefully. Note that servo library for esp8266 and ESP32 are different. Read the compilation error while compiling.

For what? Explain.

@@SMEDehradun All I will be doing is measuring the level of waste and displaying the reslut in the blynk app.So, what changes should I make in the code?

Then remove the code of ir sensor and servo motor.

Select the proper board as shown in video and install the servo library for your board.

I have posted videos on different Methods to connect with new blynk. In below video, I have shown the easiest way- th-cam.com/video/c5u6-Th1sI4/w-d-xo.html You need to add the MPU sensor code in the code and that’s it.

I have very busy schedule so I will try to post the video on data logger for Solar panel.

It can be. But prefer external power supply.

Only driver installation can help you.

@@SMEDehradun it helped me i had drivers installed now its fixed

Great 👍

This video will guide for DHT11 Sensor th-cam.com/video/c5u6-Th1sI4/w-d-xo.html

It will Not worked with wokwi.

Check your blynk credentials and wifi name and password. Also Check the issue in the serial monitor.

There is not 5V pin in this esp32 board. In Vin pin, you get 5V. You can also provide external 5V to sensor.

Then check the power and signal.

Check your com port of your board. Some it happens due to your board hardware issue.

How I can check the port of board

Below video may guide you- how to check the com port. th-cam.com/video/LpohiGf8GiU/w-d-xo.html

Ok Thank you

👍

You need to manually calibrate the servo motor as per your project requirement. Actually it’s pwm works on 3.3V that’s why.

Getsocketaddrag

didn’t get this problem here in the code.

It can be arranged. Let us know if you want.

There are lots of methods for waste segregation but for student project, you can use moisture sensor or IR sensor to monitor the wave length. You need to mortify the code for this.

​@@SMEDehradunSir what will be the diagram and code after using moisture sensor.

Try it by yourself first. And if you find difficulties then drop the comment.

​@@SMEDehradunok sir.

👍

This code is correct and working fine. And can configure it in any No of dustbin by adding sensors.

Thankyou Sir In place of smart dustbin in blynk dustbin 1,dustbin 2,dustbin 3 inside smart dustbin or separate template is needed that is we need separate templates or can make altogether in one template

You can adjust it in single dashboard. And if you want to create separate template then it can also works.

Thankyou Sir

🙏

If you follow all the instructions shown in the video, then there is hardware issue in your board.

Through mobile app. If you Watch the video, you will get the method to connect with wifi.

While your board is Not displaying com port or it shows the com port issue in computer.

Try to uninstall the driver then restart your computer then connect your board. It will automatically install the driver if it is available with window update otherwise you need to install it manually. Sometime window update resolve this issue.

@@SMEDehradun yes I have done it I guess the Arduino itself is damaged but I don't see any parts damaged I don't know what's the real reason

If you got uploading issue then there is bootloader issue in your board. Try upload bootloader. Below video may help you- th-cam.com/video/AwbcOT2z69k/w-d-xo.html

Must put all the header files inside the programming folder, change the credentials and follow all of the instructions shown in the video. I will work.

😘

Yes it can.

Help me please

Check if serial port is not open in any other software or Arduino. It may also the issue of board hardware.
