How many modules can Arduino Nano controls/handles at one time?
I am planning to use these modules listed below:
WiFi Module , Bluetooth Module, GPS Module and Oled
MPU-6050
MAX30102
BMP180 and a lipo battery
I am planning to create a health band using Blynk App to receive data from those sensors.
Is it possible?
Thanks!
Read the specification for the Nano and learn what I/O it provides. Then list the I/O needed for each device. Join the puzzle.
Oled, MPU-6050, MAX30102 and BMP180 are I2C modules you will only need 2 pins to communicate with them and the I2C bus can contain up to 125 of them. 2 more pins for the Bluetooth module, another two for the GPS. and 4 for the SPI bus of the WIFI module.
10 pins in total, 8 digital pins and two analog. If the nano could with the work.
Okay so physically it is possible on hardware but there is a chance nano might not be able to handle that load?
That's what I did initially. But after consulting a few friends, I was told that the bmp180 will have to go and be replaced by the dht11. And the gps and bluetooth module will also have to go. This will greatly limit the device's functions. So that got me worried
Don't consult those guys.
