Internet of Things (IoT) could be used worldwide with the popular use of multimedia communication systems. Recent approaches in the Internet of things (IoT) are giving unexpected solutions that once seemed impossible. Applications of the Internet of things (IoT) in multimedia communication systems will facilitate many new features in network management and operations.

The objective of the project is to create a device using a microcontroller (Arduino) with a NFC device capable of communicating with a 1st Android Phone. The microcontroller with the NFC device will send a message to the 1st Android Phone and will receive a message from the 1st Android Phone. The microcontroller with the NFC will then send the 2 stored messages to a 2nd Android Phone. The sending and receiving of the messages will be done through the NFC device to be connected to the Microcontroller and the NFC devices of the Mobile Phones. The preferred NFC device to be connected to the Microcontroller is the PN532 and the preferred Microcontroller is the Mega.

Embedded software design and coding for Microcontroller for operation of BLDC motor

An year ago I started developing a custom DDR4 DIMM module as a hobby project. By now, I have done the following: 1) Complete schematic design in Altium CircuitStudio 2) Complete footprint design in Altium CircuitStudio. The DDR4 ICs' footrpint pads are 0.35mm in diameter. 3) A list of signal classes (as a screenshot from Altium Designer, since I do not have a copy of the software) 4) Complete SPD programming kit - so that we can test the manufactured board immediately. I have not done any fanout or rules configuration, since I do not think that Altium CircuitStudio will cope with the length matching and parallel multi-routing properly - specifically for a DDR4 project requirements. What I need now is the following: 1) Route the PCB on 6 layers as per the JLCPCB capabilities. Note...

I connected a Tuya Zigbee Smart Switch with a Tuya Zigbee(3.0) Wireless Gateway through Smart Life App, and it works perfectly with the app (ON/OFF). I need someone to help me to control the same Tuya Smart Switch with my ESP8266 through the Tuya Zigbee Gateway, without using the Smart Life App. (ESP8266 and Tuya Zigbee Gateway are connected to the same wifi network, so there is no need for internet) So the command should go from my ESP8266, to the router, to Tuya Zigbee gateway to the Smart switch, as shown in the attachment. If you do not have the Tuya hardware, you can connect to my Computer using Anydesk to download to my esp8266, then we can check it if it works with Tuya

I need to make an arduino uno programe for car using potinometer and use pulsein function

hen an IGBT or MOSFET are fully "on" they are known to be saturated, when they exceed their maximum current ratings they are known to "over saturate" which will eventually cause failure of the device. While IGBT's and MOSFET's are used for very similar applications it should be noted there are two main differences, the MOSFET tends to lean towards high frequency low-power switching whereas the IGBT leans towards lower frequency and harsher switching conditions, these are just the common assumptions. Due to the fairly ruggedised features of the IGBT they normally have around a 10us short-circuit capability and a higher voltage rating which makes them a lot easier to protect. The MOSFET particularly due to their lower current density ca
