@makerblock Yus! The mysterious new #Arduino thing is the Nano R4, which fits perfectly on the Companion Core board :D https://blog.arduino.cc/2025/07/24/introducing-the-arduino-nano-r4-small-in-size-big-on-possibilities
@jack_daniel i like and approve of that appalachian work ethic - you should get a few batteries and some solar, add some older laptops, do a lights out tabletop drinking exercise a few times
think about even adding an alternator to a helical wind turbine - it may only make 50 watts or something on average but that keeps laptop servers running - you need the mix and redundancy #nec #relay #arduino #home assistant #poe #radio #osint #arroyo cluster
Gesucht:
- Zeitschaltuhr
- einstellbar + manuell schaltbar über Funk: WLAN, Bluetooth
- nachweislich keine Cloud oder E.T. Funktionen
- Bedienung über HTTP Server auf dem Gerät (eigentlich natürlich HTTPS ) oder notfalls
- Gammelapp nur wenn's sein muss
- offenes Trivialprotokoll wäre sehr schön
- brauche explizit kein Smarthomeirgendwas
Gibt es sowas, oder muss ich meine Arduinokenntnisse auffrischen?

Bitte retröten.
Rip puck of doom. This guy had a bunch of sensors inside and taught me how to use the Arduino cloud. I found that if I don't break things, even expensive things, I don't learn. I attempted to upgrade the puck with a GPS module, but it short-circuited the board with the 18650 battery, destroying both the microcontroller and half of the sensors on the shield. I was happy to avoid a battery meltdown! #arduino

Глубокий сон через JeeLib
Потребление:
- Обычно: 6-8 мА (1-2 мес)
- С оптимизацией: 43 мкА (2+ года!)
Лайфхак: отключайте ADC/UART для экономии.

@OpenLabAugsburg @angro @dronn @bitsUndBaeumeAuxMuc Cooles Projekt von 2 sympathischen Menschen. Als Basis wurde ein ESP32 Heltec LoRa32 V3 Board verwendet, der mit #Arduino angesteuert wurde. Kosten: ca 22 Euro. Weitere #Sensorik-Komponenten wie Luftdruck, -feuchtigkeit & Temperatur, wie Feinstaub und Ozon dann dazugebaut. Weil letzteres viel Strom braucht entschloss man sich für ein Solarpanel. Daten via #LoRa/TTN nach telegraf in influxDB und mit Grafana visualisiert.
Inside the Box: Everything I Did With an #Arduino Starter Kit
I've made a Resistor Calculator in a Spreadsheet (think I've got all the maths right).
Never thought when I decided to get an Arduino, I'd be trying to lean Ohm's Law.
Just built a classic Snake game on Arduino! Features OLED display, progressive difficulty, and smooth grid-based movement. A nostalgic fun with collision detection and growing gameplay.

Has anyone successfuly uploaded Arduino sketches to the Nano ESP32 using the Upload button in the official IDE?
I can only upload them by putting the board in "flash bootloader" mode, burning the bootloader and then uploading the sketch using the ESPTool programmer, which is pretty convoluted I think
EDIT: I had wrongly set up the udev rules ._.
Ein Grund warum ich lieber #SPS für alles nehme.
Es gibt immer Ersatz für Aktoren.
Voll #opensource fähig [1] und mit jeden SPS Hersteller über #Modbus kompatibel.
[1] Wenn in Ansi SPS programmiert wird und nicht die Hersteller Logik Bausteine nutzt
I've just completed the 5th project (Mood Cue), from the official Arduino Starter Kit. So far I feel I've understood most of the code.
The electronics part still scares the willies out of me. In the 5th project you use 100uF capacitor, for the first time.
It says 'Be very careful to make sure you are connecting the Cathode to ground, and the Anode to power. IF YOU PUT THE CAPACITOR IN BACKWARDS, THEY CAN EXPLODE '
Yaydio, a 3d printed DIY MP3 Music Player for Kids.
Maintaining a library of CDs is not entirely convenient either, so [JakesMD] has created the Yaydio. It’s a music player for kids [powered by a Arduino Nano with modules for MP3 playback and NFC reading], that plays music when a card is inserted in its slot.
Nur der Vollständigkeitshalber.
Du weißt das man aus dem #Arduino den #Chip, ein #ATmega328P, auch komplett alleine laufen lassen kann?
Programmieren rausziehen, auflöten, fertig.
Für eine #Paniktaste mit Buzzer braucht man keinen #Arduino.
Ich hab den Attiy aber mit einem Arduino 1999 und Arduino Software mit einem Arduino-Prg, geflasht und danach den Attiny auf eine Platine gelötet.
TRÖT TRÖT !
