Why does Arduino Nano 33 IoT always choose the weakest WiFi BSSID?
I have an Arduino Nano 33 IoT configured to connect to my WiFi network with a pretty straightforward code:
#include
int status = WL_IDLE_STATUS;
status = WiFi.status();
while (status != WL_CONNECTED) {
status = WiFi.begin(ssid,…

Arduino Nano IoT 33 Char Array size constraints
I would like to save data that I am receiving from API calls in a char array. The problem is that the data is around 80 kB, and my Arduino IoT 33 only has 32 kB of memory.
It will save data in a char array up to 25000 bytes, but when I go to 30000…

Battery solution Nano 33 iOT
Since the Nano 33 boards are quite new right now, I haven't found any details on how to hook one up with batteries.
I'm pretty daft when it comes to electronics (I'm a software man), and I read that the new Nano 33 requires 3.2V, which is a bit of a…

Is it possible to extract the firmware of an Arduino BLE or IoT board wirelessly?
I've looked at previous questions regarding sketch extraction and know that it is possible to extract the hex code from an Arduino board using avrdude from the command line.
However, I want to see if the following is possible:
Connect to Arduino 33…

Which Arduino for many analogue sensors (and WiFi)?
For context, I come from a very software-heavy background so I know very little about hardware.
I'm looking to build a system that requires at least 6 sensors (pH, electrical conductivity, humidity, temperature, light intensity, flow rate), and I…

WiFiNINA Resetting Arduino Nano IoT 33 When Powered Externally
This is puzzling me: if I power my Arduino IoT 33 Board from USB, everything runs smoothly. Now, if I power it with 5 V on Vin, the board resets as soon as I call WiFiNINA's WiFi.begin(ssid, pass).
Of course, power is my first suspect as I'd imagine…

Powering up a 16x2 LCD display with only a 9V battery
I'm using an Arduino (Nano 33 IoT) board for a project and apparently this board can only supply with 3.3 volts when a 9V battery is connected to it through Vin and GND pins. In other words, I'm powering the Arduino board with a 9V battery, but I…

Arduino Nano Ble Sense stopped working suddenly
My Arduino Nano 33 BLE Sense stopped working suddenly a while after uploading firmware for an ML project. I've used my board for several ML projects and it worked like a charm.
I can't find the board in the Arduino IDE's port section.
I've tried to…

Pulse period capture with SAMD21
I need to count the number of pulses in a moving window (e.g. last 60 seconds) using as less CPU time as possible.
The first step is to use TCC to capture pulse period.
The pulses arrive randomly at PB02 and the average frequency is about 20-100…

What is required to run a program preciously uploaded and working from Arduino IDE via PC... (Nano 33 IoT)... but now powered via VIN, not USB?
The Arduino IDE works beautifully with the Nano 33 IoT using the IDE and is powered via USB. I now want to disconnect the USB and power thru the VIN pin (6-22V). The green led comes on but the program is not there or not running. Please help. thank…

How can the SAMD21 chip knows when the on-board NINA W102 restarts
I am building a project that requires the SAMD21 microcontroller to send a resetToFactory signal to the NINA W102 on Arduino Nano 33 IoT. My plan is that, once the W102 receives the signal will do NVS formatting and restart itself, and then I need…
