Hi guys I hope you're having a good day, I want to ask you about the propellers in brushless motors, how does it effect the force, is there any suggestions for a flight that weights 400g, thank you in advance
Here's an Arduino client for MQTT: https://www.arduino.cc/reference/en/libraries/mqtt-client/ compatible with the SAMD architecture; look into it and determine your overall memory requirements. Do any of the MCUs on the platforms listed below meet your requirements?
Arduino MKR FOX 1200
Arduino MKR GSM 1400
Arduino MKR NB 1500
Arduino MKR VIDOR 4000
Arduino MKR WAN 1300 (LoRa connectivity)
Arduino MKR WAN 1310
Arduino MKR WiFi 1010
Arduino MKR ZERO (I2S bus & SD for sound, music & digital audio data)
any one has good resource for C++ for embedded As i want to learn it I can learn C++ from youtube and all but using its tools for embedded that is where i lack imagination
My name is Kuldeep Mann, software developer specialising in designing and coding complex user interfaces for about 20 years on Windows platform using C++ and .NET. My Youtube channel is about touchscreen and embedded systems which presents a very interesting and fun combination. The Pi is so small, it can be virtually taken anywhere and I am ama...
Please I need help on this guys , I am exploring STM32 microcontroller development with RTOS (micrium). Any tips for calculating thread stack usage efficiently?
so as per the judge he suggested that instead of a heavy protocol like mqtt or gsm go with POE ( power over ethernet ) and instead of esp32 you can just use any 60 cent chip it will do the work as i just need to read 5 values from 5 different sensors and upload it to internet via POE , but he didn't mention any specific cheap so i want to know what chip was he talking about
PoE should work as well. It might be easy to integrate while installation and is a fully wired method unlike other popular wireless IoT. The software-stack and processing you need in PoE case might get complex and not all MCUs come with ethernet peripheral. For example, say RA6M2. It comes with ethernet MAC (exposing RGMII lines) and an external PHY chip say DP83867 will be required to further down connect with the RJ-45 port having twisted pair lines. Also, the POE requires it's set of chips - usually a rectifier IC and PoE PD IC for handshaking to extract power from the twisted pair lines (ex: https://ww1.microchip.com/downloads/en/Appnotes/AN3533-PD70210AAL_and_PD70211_System_Layout_Guidelines.pdf)
@IoT Cloud @Edge Networking devs won't want to miss @LMtx outlining the fundamentals of MQTT topic structures in tomorrow's Ask a Developer demo. Check it out tomorrow at 15:00 GMT time:
MQTT is one of the most popular IoT communications protocols for wireless sensor networks. Its publish-subscribe architecture can streamline, simplify, and scale the creation and provisioning of potentially massive edge networks—if you structure the pubsub technology appropriately from the start.

Hello everyone , I am doing a project on automatic trash detection and collecting , in that the whole project weights about 15kg to move that body to a torque value of 2.2.75n-m is required so provide me some dc motors also the drivers of the dc motors ... with less price
In Wire Shark how to capture all the traffic of a given address ? the traffic i'm lookinng for brtween two machine 192.168.1.2 and 192.168.1.3, my ip address is 192.16831.4
Good day @info3917 . Looking at your project requirements, you might want to look into DC motors with high "torque to weight" ratios. Some options to look at are brushed or brushless DC motors with gearboxes for higher torque. So, for motor drivers, you can consider H-bridge motor drivers or motor driver ICs like L298N or L293D, which are cost-effective. Make sure you check compatibility and power requirements before making your decision.
@kumarsingh Welcome! Can you let us know a bit about your technical background, what brings you to DevHeads, and what you're looking to learn/contribute?!
We're happy to have you! You should check out our Office Hours and Engineering Hour sessions on Friday and Sunday, respectively. We also have some cool demos coming out. And if you're interested in anything you don't see or have suggestions on how we can improve, we're all ears. Just let us know!
Good morning,I have a project in which I am using Android application for object detection Currently my phone camera opens when I open the application and it starts detecting the objects But I want to integrate the esp32 cam with android so that esp32 video stream come to android and should be shown at phone's screen Basically it uses phone camera for object detection now it should use esp32 cam Can anyone help?
You can run a Webserver on a ESP32 CAM Module. And access it from Android App which can be made by using simple MIT App Inventor. So that the Mobile App will access a video stream over HTTP as a client. Also, you can add additional capabilities like the object detection algorithm running on ESP32 to acces camera stream connected to it.
