Hello all,
I recently received my Arduino Nano Every, to replace a "fake" Arduino Nano I already hadI'm using this Nano Every combined with WS2812B LEDs and Fastled (3.5.0) + Prismatik for a DIY Ambilight setup for my PCWith the fake Nano I could get baudrates up to 115200 but I wanted something faster, as such I bought an original Nano Every.
I have connected the LEDs the same way with the nano Every that I used with the Fake Nano, but don't get any output whatsoever.So I copied an example form the FastLED wiki: https://github.com/FastLED/FastLED/blob/master/examples/Blink/Blink.inoTo just blink the leds, but even that doesn't seem to workI've seen a lot of issues on github concerning the Nano Every, but I've also seen there are some people who managed to get it to work..So what I'm asking is, am I overlooking something? Is there anyone who has managed to get this combination of products to work correctly?
The sketch I used for the DIY Ambilight can be found here:https://github.com/dmadison/Adalight-FastLED/blob/master/Arduino/LEDstream_FastLED/LEDstream_FastLED.ino
I use the following values:
// --- General Settings
const uint16_t
Num_Leds = 2; // strip length
const uint8_t
Brightness = 150; // maximum brightness
// --- FastLED Setings
#define LED_TYPE WS2812B // led strip type for FastLED
#define COLOR_ORDER GRB // color order for bitbang
#define PIN_DATA 6 // led data output pin
// --- Serial Settings
const unsigned long
SerialSpeed = 115200; // serial port speed
const uint16_t
SerialTimeout = 60; // time before LEDs are shut off
SOLVED:
Well.. sorta kinda..
Using PIN 5 instead of 6 seems to work correctly
I'm building a small pedal-sized box for my friend to expand the functionality of their Behringer Neutron. They mostly just want attenuators, but I thought it could be cool to put a simple little sequencer in it as well, just for fun.
All the Arduino sequencers I've seen are much bigger and include all kinds of extra buttons and pots and jacks and switches for additional features, but since I want this to fit in a small section of a small enclosure, I am hoping to pare it down to the absolute bare minimum - one pot for the rate, one pot per step, and an output. To fit in such a small space, I plan to use trim-pots for all the pots. Of course that means it won't have the precision to hit specific notes, but the idea is for it just to be rhythmic modulator that they can add to patches, not something to play musical scales.
The only reason I want it to be Arduino Nano based instead of just making a Baby-8 (CD4017) is because I want it to be USB powered, and I don't have the parts or know-how to power a Baby-8 with USB.
How can I make this happen?
I've prototyped a project controlling a set of 600 WS2811 addressable 5v RGB LEDs controlled via an Arduino Uno. This seemed fairly straightforward, since the operating voltage of the Uno is 5v, the data line was a simple tap to an Uno pin, and power injected into the LED strips and several junctures from a beefy 5v power supply, with the Uno powered directly from that same PSU. The data is in a continuous line through all 600 LEDs.
But now I'd like to build the final project, increasing the LED count to 1000-1200 LEDs and moving to a more powerful MC with more memory (both to accommodate the added LEDs, and for additional logic).
But all the MC's I'm finding with significantly more Flash all operate at 3.3v, and I cant quite understand all the ramifications.
I know I can use a puck or MOSFET to power the MC from my 5v PSU (or move to an ATX PSU with a dedicated 3v rail), and still run the LEDs off the PSU as they are now. But how do I boost the data to the 5v the LEDs require? I've run some bench tests with an Arduino Nano 33 BLE, and the 3.3v data causes issues with the LEDs.
I don't see why not but asking just in case
I've been considering purchasing an Arduino Nano for a project of mine, but I can't help but notice the nubs along the side of it in the images; are the wires you attach to it supposed to grab onto those somehow? Or maybe it interlocks with the bottom in someway?
I have found anything online to using MIDI out with a 5 pin DIN plug and the Nano 33 IOT, other than it is like doing it with an Uno?
Can anyone confirm or deny? I thought the Nano was 3.3 volt, and I wasn't sure if that would make a difference to the MIDI device.
Hey, about a month ago I got my first Arduino, a Nano 33 IoT, because I wanted to build a weather station. So I bought the Arduino and a DHT 22 temperature and humidity sensor. I planned on powering it with a 5000mAh powerbank.
At the first try I did not care about power usage and kept the Arduino always on as well as reading data from the DHT 22 every two seconds. One day later the powerbank was out of juice.
So I sat down again and found out that putting the device into deep sleep should save quite some power. I came up with the following code:
#include <ArduinoBLE.h>
#include <ArduinoLowPower.h>
#include <DHT.h>
#include <DHT_U.h>
#define ADVERTISING_INTERVAL 10 * 1000
#define DEEP_SLEEP_INTERVAL 15 * 60 * 1000
// store weather sensor type, data pin and delay between sensor reads
const byte dhtDataPin = 2;
const byte dhtPowerPin = 3;
const short dhtDelay = 2000;
// environment service (16-bit UUID: 181a -> Environmental Sensing)
BLEService environmentService("181a");
// humidity characteristic (16-bit UUID: 2a6f -> Humidity): readable & subscribable
BLEUnsignedIntCharacteristic humidityCharacteristic("2a6f", BLERead | BLENotify);
// temperature characteristic (16-bit UUID: 2a6e -> Temperature): readable & subscribable
BLEIntCharacteristic temperatureCharacteristic("2a6e", BLERead | BLENotify);
DHT dht(dhtDataPin, DHT22);
void setup() {
// set built-in LED to output mode
pinMode(LED_BUILTIN, OUTPUT);
// ********** BLE SETUP **********
// begin initialization of BLE
if (!BLE.begin()) {
// show that BLE startup failed
digitalWrite(LED_BUILTIN, HIGH);
while(1);
}
// configure BLE
BLE.setLocalName("Weather Station");
BLE.setAppearance(0x0552); // appearance of environment service (0x0552 -> Multi-Sensor)
BLE.setAdvertisedService(environmentService);
// add the characteristics to the service
environmentService.addCharacteristic(humidityCharacteristic);
environmentService.addCharacteristic(temperatureCharacteristic);
// add service
BLE.addService(environmentService);
// ********** DHT SETUP **********
pinMode(dhtPowerPin, OUTPUT);
dht.begin();
}
void loop() {
// read current sensor data
updateEnvironmentService();
// startI’m working on a project and was wondering if theres a way to use my lego mindstorm sensor on the arduino, I remember seeing a method but I can’t seem to find it ! I hope someone has an idea of what I’m talking about, thanks
Hi I saw a cool project I would like to make and it says you need an arduino nano r3. But I haven’t been able to find it on the official arduino site or on Amazon. Is it the same as an arduino nano? I think the r3 might’ve thrown me off.
Thanks for the help.
I’ve heard about this arduino having the ability to implement TinyML (which I think is Arduino’s version of ML) and wanted to understand if it can be used for medical devices or virtual assistants as well. Please do share your thoughts as I have very minimal knowledge about Arduinos in general and only worked on an Arduino Uno
