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 want to program a simple Webserver with an ESP8266 but I want to connect the ESP8266 to an Arduino Mega. I want to connect a LED and a Sensor to the Arduino and control the LED and read the sensor data via the ESP8266 Webserver.
I am a beginner and dont want too complex solutions. It's just a simple school project.
For the Webpage I am sending just some HTML Code, I do not use Blynk or anything like that.
My question is how can I connect the ESP8266 to the Arduino and control it's pins?
There is a million ways to connect an ESP to an Arduino.
Without any shields or perihperals you can basically use any wired bus that does not require transceivers.
For example I2C or SPI.
With shields or peripherals you can use CAN, LIN, RS232, Ethernet, WIFI, Bluetooth, radio, optical and audio transmission... The list is endless.
You can of course read a sensor with the ESP so an Arduino Mega is not really necessary.
I wanted to connect arduino mega with GSM shield(mounting) and a ultrasound sensor with a battery(9V) to post data and send SMS. but it was working for 10 minutes and stops working i.e the lights are on but the signal is not constant(checked with all the networks and signal strengths : no issues there). It is working properly with new battery for 10 minutes(tested with several new batteries)Is this power issue. If yes, please help me resolve this issue.
-Is GSM shield mounting creating the problem?
-how to get a long battery life with arduino and GSM shield.
Thanks,
Sandeep
This is power issue, GSM modem uses 1W (200mA at 5V) of power on 850/900 MHz, and 2W on 1800/1900 MHz, and GSM shield requires peaks of up to 2A current.
You need more batteries or dc power supply.
I am trying to do a project based on arduino and Android in which I want to use ultrasonic sensors and Bluetooth module hc-05 . I want to detect any obstacle using ultrasonic and send it's distance to Android app using Bluetooth. I am completely new to arduino and have never used it before . How could I connect both the Bluetooth and ultrasonic sensor to arduino uno board without using breadboard? Is it possible to connect both of them without using breadboard and just the jumper wires?
You can connect the Bluetooth Module and Ultrasonic Sensor with jumper wires directly to the Arduino.
Depending upon the Ultrasonic Sensor you are interfacing, there must be a library or a sample code. You can tweak the code to get the distance in your desired format or variable.
As far as the Bluetooth is concerned, you can operate it at 3.3v or 5v depending upon the module you use. Most of the Bluetooth module support both 3.3v and 5v - as they have voltage regulators on their break out. I have used these and they work on 3.3v as well as 5v
For instance, check the Bluetooth HC - 05 Module in the below link :
http://www.amazon.in/Verve-VTA009-Bluetooth-Module-HC-05/dp/B00S15XTG8?tag=googinhydr18418-21&tag=googinkenshoo-21&ascsubtag=7a58e842-4c10-40bf-a48f-339edef372a7
For implementing the Bluetooth communication, prefer using the Software Serial. If you connect the Bluetooth HC 05's Rx and Tx to the Arduino's Hardware UART Pins, there can be unpredictable results. I have experienced that using HC05 with Software Serial is reliable. Additionally, you can use the Serial Monitor to debug your code at the same time. I mean, you can send the same data on Software Serial and the Serial port and check if things are as desired.
You can implement, the HC-05 Software Serial at 9600 baudrate. 9600 is the default baudrate on most HC 05 Modules.
For developing the Arduino code and testing it, you can use a terminal client like PuTTY on you computer. You need to establish a bluetooth connection between your computer and HC 05.
HC-05 runs at 3.3V, make sure you do level conversion from 5V to 3.3V using a zener diode. Or buy a level converter if you are new to electronics. If you don't, there is a good chance you will blow up the HC-05. If you could add a photo we can see if its already done on the Bluetooth module, then you need not worry about level conversion
HC-05 is basically a wireless serial port over bluetooh. On arduino create a software serial post using the library SoftwareSerial and send the sensor data to that serial port
There are libraries available for popular HC-SR04 ultrasonic sensor, if that is the sensor you are using.
For testing on android many app are availables like Bluetooh Terminal, you can receive the data sent from arduino.
Yes the whole project can be done without breadboard using connecting wires.
I'm just starting out some studies with XBee S2 and Arduino and I'm not sure if I'm doing what I actually planned.
My idea was to use just one Arduino with one XBee (Coordinator) that would receive the DHT11 data from just Router XBee (without another arduino to process the DHT data) and save the Coordinator temperature and humidity in a database.
Searching for some results I found out that XBee is unable to send DHT11 Sensor signal to another XBee ( thought I could send the DHT data through some router XBee Pin).
So do you guys have any ideas on how I could fix this? Because using another arduino into my Router XBee would be a waste of battery, losing the purpose of a sensor network right? Do you guys recommend me to change the sensor or what?
Besides I'm using Arduino Uno, Libellium XBee Shield, XBee S2 and of course DHT11.
Based on the DHT11 Adafruit page, I'd say you'll need an extra processor to read the data:
...and spits out a digital signal on the data pin (no analog input
pins needed). Its fairly simple to use, but requires careful timing to
grab data.
You may want to consider one of Digi's Programmable XBee products, which includes an additional 8-bit Freescale processor on the radio module, which you could program to read the DHT11 and relay its data to your coordinator. Certainly a less-expensive solution than having an Arduino make that conversion.
Or, switch to a humidity sensor with an analog output that doesn't require digital conversion. SparkFun has a Honeywell HIH-4030 Breakout board that looks appropriate.
If your goal is to just have a remote humidity sensor, one last option would be to purchase a standalone, battery-powered sensor from Digi. They have a light/temperature/humidity sensor (here's the datasheet) with an XBee inside that should be easy to interface to your Arduino. It's been designed to run efficiently on batteries for an extended period of time. My understanding is that it uses the analog inputs of the XBee to relay the sensor readings.
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.
