I am referring the options to choose antenna for data transfer over Bluetooth 5. Any guidelines to choose between these two- SMD Chip antenna or PCB track antenna.
Thanks.

I'm doing a project in which I have to constantly monitor the acceleration, gyroscope and heart pulse rate and based on that I have to send location info to particular numbers. Apart from this, I have to send the pulse rate & location info to Google firebase.
Components required:
Arduino Uno
GPS Module
GSM Module
Accelerometer/Gyroscope sensor
ESP8266 01 WIFI Module
Pulse Oximeter sensor
I'm new to Arduino environment. I don't know if I can use all these peripherals simultaneously. Can you please let me know.
Thanks in advance
Arduino Uno has
2(SDK,scl) for I2C
1 spi,
1 UART
most of the above module supports I2C. you can connect multiple slaves to the single master.
you can make Arduino as a master and others as slave
I have A UART transmitter written in VHDL and want to transmit data from FPGA Rs232 to a PC that only has a USB.
My question is, is it fundamentally a correct assumption that USB can receive serial data? I'm basically treating the USB as an Rs232 receiver.
If this is correct, what program can allow me to monitor the USB incoming data?
Thanks in advance
USB port includes 1 differential data line + 2 power line, that makes 4 cable(I mean version <= usb2.0).
RS232 is full duplex data transmission protocol which you can't do it with USB2.0(USB3.0 is full-duplex). And it has additional control lines. It doesn't include power line. It has variable voltage levels(up to +-25V).
Simply, yes you need a converter.
USB
RS232
As I am thinking to do a Home automation using Arduino, using Light sensor, temperature control , motion sensor , gas leakage sensor , fire detection sensor , hall effect sensor for Light on/off , fan on/off and fan speed control , motion detection , alarm for gas / fire detection , door open/close respectively.
But my question is how many sensors will work at a time in at an Arduino board?
And is it possible to control Arduino by using PIC or i.MX6 Dual Lite/Solo?
If the sensors use I2C then the limit is 128 devices on the bus, but they each have to have a unique address which are sometimes "hard-coded" on the device by the manufacturer. The Arduino Wired library is used to read/write I2C and it only takes two pins. I2C is also sometimes called TWI (Two Wire Interface). The PIC can do I2C, not so sure about the i.MX6 but I've controlled an Arduino over I2C using a Raspberry Pi.
For the Arduino Uno go here to find the specifications of the open source design:
http://arduino.cc/en/Main/arduinoBoardUno
There you will read that the Arduino Uno has 14 digital and 6 analog I/O pins.
Note, you are not limited to the number of sensors based on the number of I/O pins.
Example:
Any processor has a limited number of I/O pins. You can add hardware to multiplex external signals before they get to these I/O pins. For example, say the processor has 4 I/O pins. You can devote 3 to control a multiplexer selecting 1 of 8 signals to route to the 4th processor I/O pin. Thereby doubling the number of inputs you can sample.
You can use many number of sensors as you wish. But your board need to have that much I/O pins. Try to get mega Arduino board. Arduino Mega 2560 has 54 pins totally. So in the mega board you can connect many sensors.
You can also control the board by PIC, Arduino sketch and so on.
Just beginning to to understand with arduino. I plan to put together a small device that accesses the internet at the site, and then, depending on the information that plays a mp3 file. From the annotation of to the Enternet Shield mp3 Shield and read that they both involve the 10-pin, and thus come into conflict. What to do in such a case, or is there an opportunity for playing time off Ethernet Shield and vice versa?
I dont know about your mp3 shield but on the ethernet shield pin 10 is the Slave Select pin.
The MISO, MOSI, and CLK pins can be shered with other shields but not the SS pin.
The only way to solve this would be to cut the connector from the mp3 shiled and connect it to antother pin. Then you will also need to recompile the libs for your mp3 shield to reflect the change of pin.
For further information see Arduino SPI, Arduino Ethernet
I want to start a project using arduino microcontroller board. In this project I will use a Mini Thermal Receipt Printer, barcode scanner and the arduino ethernet shield to transfer data to my pc and from my pc. my question is, what arduino board should I buy for such project? is the arduino uno is enough?
The choice of a right Arduino depends on the sort of peripherals you need for example if your barcode reader is SPI enabled and you can't bit-bang SPI then this counts for Hardware SPI usage and as such will take the SPI pins on the UNO which has support for only 1 SPI hardware connection but if you want more SPI connections go for a MEGA ,similarly UART, two wire etc are communication protocols that may be needed by you based on the chipssets you use in your project, also GPIO's are there which just turn on and off.
I will suggest starting off with an Arduino UNO which DIP ATmega328P and get a spare Bootloader acquipped ATmega328P chip standalone in case as a newbie you magic-smoke the chip on the board.
