Proximity sensing is a very common application in electronics. There are several ways to accomplish this. The most common way is by using a PIR sensor. PIR Sensor senses the change in ambient infrared radiation caused by warm bodies. I have already covered this in my Tutorial No. 5: "PIR Sensor Tutorial - With or Without Arduino". However, since PIR sensors detect movement from living objects, they can generate false alarms. These sensors are also inefficient in hot environments, as they rely on heat signatures.

The other common methods of proximity sensing involve, using reflected ultrasonic or light beams. Using these sensors, the intruding object is detected by the reflected beam back to its source. The time delay between transmission and reception is measured to calculate the distance to the object. In this tutorial, we are going to look at another method of proximity sensing using "Microwaves" and "Doppler Effect".  In my hand is an inexpensive RCWL-0516 Microwave Radar Motion Sensor. The RCWL-0516 microwave sensor detects "any movement" from "any object" and does not rely on heat, making it more reliable in hot environments. I am going to use this sensor to create a Geo-fence around my house to detect motion and get notifications.

Zeitmessung per Funk: DCF77-Empfangsmodul mit Arduino

Mit einem DCF77-Empfangsmodul lassen sich exakte Zeitdaten von einem Funksender wie dem DCF77 empfangen. Diese präzisen Zeitsignale sind ideal für Projekte mit einem Arduino, bei denen eine genaue Uhrzeit erforderlich ist, etwa für zeitgesteuerte Schaltungen oder Datenerfassungssysteme. Das DCF77-Signal wird von der Physikalisch-Technischen Bundesanstalt (PTB) über eine Sendeanlage in Mainflingen ausgestrahlt und stellt eine zuverlässige Quelle für die Mitteleuropäische Zeit (MEZ) sowie die mitteleuropäische Sommerzeit (MESZ) dar. https://www.youtube.com/watch?v=JARqWmHE6Kc&t In diesem Beitrag zeige ich dir, wie du ein DCF77-Empfangsmodul mit dem Arduino verbindest, die empfangenen Daten dekodierst und für dein Projekt weiterverarbeitest. Statt vorgefertigte Bibliotheken zu verwenden, biete ich dir einen einfachen Code, den du direkt in dein eigenes Projekt einfügen kannst. Dadurch behältst du die volle Kontrolle über die Signalverarbeitung und kannst die Daten flexibel an deine spezifischen Anforderungen anpassen. Dieses Projekt eignet sich sowohl für Einsteiger als auch für Fortgeschrittene, die präzise Zeitsteuerungen oder Datenerfassungen umsetzen möchten.

Wozu dient das DCF77-Empfangsmodul?

Das DCF77-Empfangsmodul dient dazu, über Funk genaue Zeit- und Datumsinformationen zu empfangen, die von der DCF77-Sendeanlage ausgestrahlt werden. Diese Informationen werden mit einer hohen Genauigkeit über eine Langwelle (77,5 kHz) gesendet und sind besonders nützlich für Anwendungen, bei denen eine präzise Zeit erforderlich ist, wie etwa bei Funkuhren, Zeiterfassungssystemen oder zeitgesteuerten Schaltungen. In Arduino-Projekten ermöglicht das DCF77-Modul, die empfangenen Zeitdaten in Echtzeit zu verarbeiten, ohne auf externe Zeitserver oder manuelle Einstellungen angewiesen zu sein. Dadurch wird es zu einer idealen Komponente für Automatisierungen, bei denen eine verlässliche Zeitsynchronisierung entscheidend ist. Sender DCF77 in Mainflingen Der Sender DCF77 überträgt die Daten dabei mit einer Frequenz von 77.5kHz und einer Leistung von 50kW.

DCF77 Zeitzeichensender bei Mainflingen (Frankfurt am Main) Zu diesem Sender gibt es einen Ausführlichen Wikipedia Artikel, welchen ich hier nun gerne verlinken möchte: Seite „DCF77“. In: Wikipedia, Die freie Enzyklopädie. Bearbeitungsstand: 6. September 2019, 12:10 UTC. URL: https://de.wikipedia.org/w/index.php?title=DCF77&oldid=192027822 (Abgerufen: 13.

Bei BCD werden die oberen 4 Bits des Bytes als Zehnerstelle und die unteren 4 Bits als Einerstelle interpretiert. Die Funktionsweise im Detail: - Mit raw >> 4 werden die oberen 4 Bits des Bytes nach rechts verschoben, sodass die Zehnerstelle isoliert wird. - raw & 0x0F maskiert die oberen 4 Bits und behält nur die unteren 4 Bits, die die Einerstelle darstellen. - Schließlich wird das Ergebnis als Dezimalzahl berechnet, indem die Zehnerstelle mit 10 multipliziert und die Einerstelle dazuaddiert wird. So ergibt sich aus einem BCD-Wert wie 0x25 (Zehnerstelle 2, Einerstelle 5) die Dezimalzahl 25. unsigned int rawByteToInt(byte raw) { return ((raw >> 4) * 10 + (raw & 0x0F)); } Read the full article

What's the thing that's probably wrong with this very cheap robot arm? I know the good ones start at like $10k so presumably it's something. https://www.amazon.com/LewanSoul-Robotic-Arduino-Software-Tutorial/dp/B074T6DPKX?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&psc=1&smid=A1K1UK7O5KP6WQ&gQT=1

(clickable link) looks like your average cheap servo arm -- lots of pinch points and low weight capacity, but the real problem is the precision, or lack thereof. there's gonna be a lot of slop and backlash, which makes the already tricky project of manipulation basically impossible for anything more difficult than Brightly Colored Foam Cubes. fortunately the natural habitat of this type of arm is, like, "learn to robotics!" school projects where Brightly Colored Foam Cubes are the only kind of object in existence. (but keep in mind that i'm no big city mechanical engineer or anything.)

The first test for our WLED board codename "Sparkle Motion" 🌈💖💡 … 🐇⏳🌌

We got our WLED-friend PCBs today, and we only made one mistake: the wrong resistor on the 3.3V feedback line. Now that it's fixed, the board seems to work great with the latest version of WLED

We are checking all 4 signal outputs with this handy 256-LED grid that sits on our desk. Next, we will test the onboard IR receiver, USB PD, I2S microphone, extra I/O pins, and I2C. We'll also do an Arduino IDE board definition in case folks want to use it as a generic ESP32-to-LED-driver board. We're calling the board "Sparkle Motion" for now, but if you have other naming ideas, let us know - if we pick your name, you get a free board

For the past several months I've been working (and am still working on) a cosplay of my OC George Jackdaw. George is a corvid bard, a jackdaw in fact, who didn't have a last name so it'll just put down it's species instead.

I'm using mostly @rah-bop 's tutorials (bless you and your tutorials on Rue) and a pattern from Etsy for the head. Here's some progress pictures, because I'm nowhere near finished:

The mask is an EVA foam base from an etsy pattern for a corvid skull. I'm still racking my brain on how to add the eyes in there with me still being able to see.

Speaking of which, here's a little clip from my Twitch stream(same handle as here) that shows my prototype of animatronic eyes with an Arduino Nano Every. I've since changed the eyelid base from foam to 2mm aluminium wire.

And some tail feathers that I added metal wire to for support (not pictured). I added flexbond primer today (also not pictured because I've been too busy) and sadly it covered a lot of the lines I scored in for detail, so I'll need to figure out a way to fix that. Or not.
