wonderful controler for many projects easy tp use and fun

I have been having a great time with these. I am using them for model railroading. This should not discourage use of these Arduino products as they are so versatile. Great quality, great cost and very compact. I have used them for actuation crossing gates when a train is detected along with lights and sound. Automated street traffic lights. The list goes on. Programming is straight forward when familiar with the syntax. I have also combined with relay boards to control different voltages and loads.

I buy these things by the gross (exaggeration). Use Claude on my mac to program. Reliable, easy to set up that way, no faffing with the serial loader and editor. Get the matching sunfounder case.

It worked nice and very durable it is grate value

I mean there isn’t really much to say, I used it and it performed well. The only caveat is that it isn’t able to perform fast enough for my rotary encoders. I optimized my coding as much as I could and I could get about two working at max rotation speed. I had five to test out and it worked okay until I tried three. They stopped reading some of the updates and began to register positive numbers only when I rotated the knobs slowly. The display screen works perfectly though. I feel that things that need to get new update states as frequently as possible to work well is not really the best way to use this. But it still works very well and I can just have the knobs change to negative or positive with a single knob since I have so many. Overall, great microcontroller. I still haven’t tested out the wireless transmission or built-in leds yet so hopefully when I get to that it will work as it should. Very great. The hardware is well built and soldering is as expected. Currently I am testing out an led strip controller with knobs and a display screen and that is working well so far. Very nice.

The Arduino UNO R4 WiFi is an updated version of the classic Arduino board. What makes it special is that it’s faster and already comes with Wi-Fi and Bluetooth, so you can connect your projects to the internet or even control them from your phone. It looks almost the same as the older Arduinos, so you can still use the same cables and accessories. It also has a little LED matrix (like tiny lights) that you can program to show numbers, symbols, or messages. This board is perfect if you are just starting to learn, because it’s simple to use but also powerful enough to create fun and modern projects like smart devices, robots, or interactive systems.

Works super. You need to add simple command interface through com port that will let you set up wi-fi. Then create an http host for your interface. No need to physically wire up switches or buttons or dials. Remember no blocking code. I can see why people use these as Christmas tree light controllers. I can think of a dozen uses for this thing right off. A note on the http interface. Only allow two or three channels at most. There's just not enough RAM to support anymore. Since there's absolutely no room to store anything like a graphic. I created a public facing folder on my Google Drive and put my Graphics assets there and then have the http interface access those through a link so that it doesn't have to store the graphic locally. The only thing that should be stored on the EEPROM is the Wi-Fi setup information. Everything else should be stored on the client's machine AKA your laptop connected to the host running on the Arduino. $$$ BE AWARE! The Visual Studio extension is NOT free. $$$

De arduino is beschadigd aangekomen

Ich nutze den Arduino UNO R4 WiFi seit einigen Wochen für diverse Smart-Home- und IoT-Projekte und bin absolut begeistert vom Leistungssprung im Vergleich zum klassischen R3. Das Board kombiniert den gewohnten Formfaktor perfekt mit moderner 32-Bit-ARM-Leistung und nahtloser Funkkonnektivität. Besonders positiv fällt die hohe Rechenpower des ARM Cortex-M4 auf, die selbst anspruchsvolle Aufgaben mühelos bewältigt. Die Einbindung von WLAN und Bluetooth über das ESP32-Modul funktioniert in der Arduino IDE dank guter Bibliotheken gewohnt einfach; erste Datenströme in die Cloud standen bei mir nach wenigen Minuten. Ein echtes Highlight ist die integrierte 12x8-LED-Matrix, die sich ideal für schnelle Statusanzeigen ohne zusätzliche Verkabelung eignet. Ein kleiner Kritikpunkt betrifft die Kompatibilität: Manche sehr alten Drittanbieter-Bibliotheken des R3 laufen aufgrund der neuen Architektur noch nicht auf Anhieb und erfordern manuelle Anpassung im Code. Trotzdem ist der UNO R4 WiFi das derzeit beste Board für zukunftssichere IoT- und Automatisierungsprojekte. Sowohl für ambitionierte Einsteiger als auch für erfahrene Maker ist das Board jeden Cent wert – eine uneingeschränkte Kaufempfehlung!

Funciona!
