This summer 2019. We can hardly wait! Just think of all the possibilities this small, lightweight microcontroller can do. 

New Arduino Nano 33 IoT
1. Secure WiFi and Bluetooth connectivity with a 6-axis IMU.
2. Pre-certified module with external processor ensures maintaining RF compliance when writing application code versus ESP32 modules where modifying code impacts certification.
3. On-board DC-DC power supply enables the board to be powered up to 21V maintaining high efficiency and offering a lot of current to external devices without overheating. This is a big improvement over other products on the market that have LDO and heat up quite a bit when powered at high voltages.

The Nano 33 IoT is essentially a MKR WiFi 1010, but sacrifices a battery charger and shield compatibility in favor of a miniaturized footprint and lower cost. The Nano 33 IoT is built around the ESP32, which is primarily aimed at WiFi but supports Bluetooth as well, although with higher power consumption than the Nano 33 BLE.

Matlab on iPhone & iPad Devices

Do you want to use your iPhone or iPad to collect data from built in sensors such as acceleration, angular velocity, orientation, magnetic field, and GPS?


In this blog I will explain how to use MATLAB to collect data and log it.

First you will need access to MATLAB. Next, download the Mobile MATLAB app via Apple Store. From your lab top you will need to download the add-on 'MATLAB Support Package for Apple iOS Sensors'. 

Once all downloads have been made, open the mobile app and press the icon at the bottom right labeled 'More'. There you will see the Sensors option. Press it. This opens the menu for five (5) different built-in sensors. To begin, turn on one or more sensors. After the selection has been made, you can stream to MATLAB or log the data. 

Next, press the start button to collect data from your iOS device. *Before getting started you can change the frequency. If you chose to log the data, access the new file by pressing the icon to the right of the start button. See screenshots below.
