Hello,
I am absolutely new here with quite an ambitious project I've come up with.
I am designing an alignment rig consisting of four Arduino Nano 33 IoT. Each Nano has three sensors and an OLED screen connected to display the information from the sensors.
Because I want to stream the live data from all four Nano boards to excel, I think to connect them to Mega or Uno and then the data from the Mega or Uno stream live in Excel.
So is this doable or the Nano is not powerful and fast enough.
See the block diagram with the information of the sensors connected to each Nano board:
Without data rates and volume of data It is impossible to guess accurately. I would build one with a 5V Nano (not IOT) and and determine how much data is actually being moved around and how fast. Also the Nano 33 IOT is a dual core processor that has a lot of computational and I/O speed. Also using 5V devices and 3V3 devices requires level translation.
I suggest putting a rough schematic together, not a frizzy picture and start writing your code for each sensor. Post that per forum guidelines.
Just ordered Uno Wifi Rev2. It seems the support for the Uno family is bigger than for the Nano 33 IoT.
I got the OLED display and the WitMotion HWT905 Inclonometer sensor delivered the other day so over the weekend I managed to make the OLED work with a sample test library but the inclinometer is giving me grief. It comes with the Arduino UnoRev3 library but when I try to verify it in Arduino IDE it shows errors.
I wonder if the library was created for Uno Rev3 and I try to run it on Arduino Nano 33 IoT could be the problem?
That's why I ordered today Uno and will try that way.
P.S. This is the very first time I touch Arduino and coding language.....So please if someone has any suggestions chime in. Cos I moved to Uno Wifi Rev2 board I will start over the topic in the appropriate section of the forum.
Hi!
I can see you use an inclinometer connected to the Nano 33IOT. This board has built-in IMU with accelerometer and gyroscope.
If your set-up allows the card to be placed on the moving object, that could be a substitute.
As 33IOT can also handle wifi (and BLE but you're looking for high rate data), it could be a way to connect to a PC or a dedicated website.
I decided to go with that sensor cos it has 32-bit MCU processor and Kalman filtering. The accuracy is high at 0.05-degree static.
