difference between web server and cloud platform
Hi guys what I am in the process of implementing IOT project but I am confusing about the web server and cloud platform. May I know the use case and difference between them
Solution:
Hi @kingrom webserver is a server mostly used in embedded to host webpages. On the other hand, when you say Cloud platform then it's a digital infrastructure built on the top of a server. These terms sometimes are subjective. When and where to use them completely depends on the goal of your project.
How to Get Hands-On Learning in IoT with Arduino and ESP8266?
hi! im new to IOT can anyone please tell me how i can learn it like i have a Arduino an esp8266 and a sensor i try to work with them i dont know which pins to connect with whom and what not all the iot courses i could find keep yapping a lot like its 99% theory and 1% useless info i want some hands on learning
Solution:
Hi, @Yajat_Kaul I suggest to start with NodeMCU ESP8266 and Arduino Uno. The knowledge of microcontroller, processors, and protocols (wired & wireless) is essential to interface various sensors. This knowledge will help you build IoT devices from scratch like Node and Gateways. Let us know the specific question/topic you need help with in IoT and embedded systems. Best wishes!
Why do my CJMCU-8128 sensors fail to initialize on Arduino Uno for my IoT project?
I am working on an IoT project for my final year. The project is smart carbon capturing efficiency using IoT. I am using CJMCU-8128 Sensor which comprises of three sensors: CCS811 sensor for reading CO2 and Volatile Organic compounds, HDC1080 for reading temperature, and BMP280 for reading pressure. I have connected the sensor to my Arduino Uno board, and have also programmed the sensor. However, after compiling and uploading the code to my Arduino Uno board, its keeps telling me that the sensor...
Solution:
Hi @Minister John Please cross check the slave address from the datasheet. Just make sure your i2c sensor initializes properly in case if you don't receive data. I suggest using debugger to debug and see what's going on in the code. Unfortunately, I haven't had an opportunity yet to work on the sensor you mentioned.
Why is my NodeMcu ESP8266 not connecting to Arduino IoT Cloud despite successful code uploads?
Hey guys @Middleware & OS I'm trying to connect my NodeMcu ESP8266 V3 Lua CH340 Wifi Dev. Board to the Arduino IoT Cloud platform, but I'm facing issues. Although the board is not listed in the devices section, I've tried uploading code to various similar boards (NodeMCU 0.9, NodeMCU 1.0, LOLIN(WEMOS) D1 R2 & mini) using the Arduino IDE. The code uploads successfully, but the devices remain offline in the Arduino IoT Cloud dashboard.
Here's the output from the upload process:

Seeking Assistance with Typed Search System for Electronic Components Organizer
I’m working on a project to build a storage system for electronic components where its kept inrack’s drawer. Inspired by the FindyBot3000, I aim to create a typed search interface instead of a voice-controlled one. The system will allow users to type in component names, which will then be located and blink one LED. Can this system run on local Wi-Fi without connected to internet? If anyone have any idea please guide me.
Solution:
Yes, this can be able to run on local wifi. You ought to use a router then configure it to access mode and connect as many devices that it can handle. You can use an ESP32 MCU in this also.

how can I connect a PIR motion sensor running on a RPi with Ubuntu Core to AWS IoT Greengrass?
@Middleware & OS
Hey guys, how can I connect a PIR motion sensor running on a Raspberry Pi with Ubuntu Core to AWS IoT Greengrass, and trigger actions based on detected motion? I'm encountering challenges in configuring the sensor data to properly interact with AWS IoT Greengrass....
Solution:
Hi @Boss lady , in order for you to connect your PIR sensor on Raspberry Pi to AWS IoT Greengrass for motion-triggered actions you could try checking out the following:
- Provide a Greengrass core device and create a group in the AWS IoT console.
- Install Greengrass core software on your Raspberry Pi.
- Develop a Lambda function to process sensor data and trigger actions.
- Create a Greengrass recipe with your Lambda function and configure it to subscribe to the PIR sensor data topic and publish messages to the cloud upon motion detection....
Establishing MQTT Connection with Private Key - is that secure?
In this video, I discuss using a Private Key in the MQTT connection setup. It's crucial to keep the Private Key confidential and not share it with any third party. At the same time, we must provide that key during the connection. Is that secure? I often get that question. In this video, I share my answer.

Ensuring Synchronization and Reliability of Custom Device Logs with AWS IoT Cloud
Hey guys @IoT Cloud I need to ensure custom device logs, like ambient temperature data sent every 3 minutes, are synchronized with AWS IoT Cloud without duplicates or missing entries. Logs on the device are overwritten in a rolling fashion.
What is the standard approach for this? Is there a specific AWS tool or location that fits this use case, such as Device Shadow? Should each log type (e.g., temperature, error codes) have its own topic? I’m also looking for examples of how to implement this. What terminology should I use to find the correct information?...
Solution:
To sync device logs with AWS IoT Cloud without duplicate follow this steps
1. Send logs from your device to AWS IoT Core using MQTT or AWS IoT Device SDKs.
2. Set up a Thing and enable CloudWatch logging in AWS IoT Core.
3. Use CloudWatch Logs to store and process logs....
How can I retrieve the UUID of the inserted record?
Hey guys @IoT Cloud i have devices that collect few samples each week, storing the data indefinitely. Using AWS IoT, I’ve connected the devices to IoT Core and can publish/subscribe via MQTT. A rule forwards payloads to an HTTP endpoint, which inserts records into an RDS database and returns a UUID.
Previously, I sent JSON directly to the HTTP endpoint, received the UUID, and stored it with the sample on the device. However, with MQTT, I can’t receive the UUID back. The response only includes the original message. How can I retrieve the UUID of the inserted record? If this approach is incorrect, what alternative should I consider?...
Solution:
To retrieve the UUID of the inserted record, consider these options:
1. Use AWS Lambda to process the message and return the UUID.
2. Implement a callback mechanism to store and retrieve UUIDs.
3. Use a correlation ID to match responses with original messages....
Best Practices for Storing Device-Specific SAS Tokens for Multi-Endpoint Communication
Hi guys @IoT Cloud I plan on making a solution where devices need to communicate with multiple endpoints, including an API for non-telemetry data. To avoid additional authentication methods, I'm considering using device-specific SAS tokens generated by a back-end service. Would it be safe to store these tokens in desired properties, or is it better to use the payload of a cloud-to-device message? Are there other recommended approaches for this?
Solution:
Storing SAS tokens in desired properties or cloud-to-device message payload has security risks. Consider alternative approaches like device-specific certificates or OAuth for secure authentication and authorization. Consult security experts for the best solution.
I think @LMtx can help out here...
