In diesem Video erfährst du, was hinter dem Projekt Cyberfly.IO steckt, was der CFLY-Token ist und wie du mit einer eigenen Node am Netzwerk teilnehmen und CFLY verdienen kannst.
Cyberfly.IO ist eine moderne Web3-IoT Plattform, die Geräte, dezentrale Datenspeicherung, Wallet-Funktionen und Automatisierungen verbindet. Sie ermöglicht es, Daten sicher zu speichern, Geräte intelligent zu verknüpfen und Prozesse mithilfe von Blockchain-Technologie zu automatisieren.
Der $CFLY Token dient als zentraler Bestandteil des Ökosystems. Er wird verwendet, um Funktionen und Belohnungen im Netzwerk zu steuern. Ein großer Anteil der Tokenmenge ist für Node-Betreiber vorgesehen, die das Netzwerk unterstützen und dafür regelmäßig CFLY-Belohnungen erhalten.
Das System beinhaltet zudem deflationäre Mechanismen, die langfristig für Stabilität sorgen sollen.
Wenn du eine eigene Node betreibst, übernimmst du Aufgaben wie Datenspeicherung, Validierung oder Bereitstellung von Diensten im Netzwerk.
Für diese Aktivitäten wirst du mit CFLY-Token entlohnt – je nach Aktivität und Stabilität deiner Node kann dein Ertrag variieren.
Wie bei allen Blockchain-Projekten gibt es Risiken. Der Tokenpreis kann schwanken, und die tatsächlichen Erträge hängen von der Nutzung des Netzwerks und deiner technischen Umsetzung ab. Eine stabile Internetverbindung und geeignete Hardware sind daher wichtig.
Cyberfly.IO bietet eine spannende Möglichkeit, durch die Kombination von IoT und Blockchain-Technologie passives Einkommen zu erzielen und gleichzeitig zur Dezentralisierung des Netzwerks beizutragen.
Wenn du dich für neue Web3-Projekte interessierst, ist Cyberfly IO definitiv einen Blick wert!

Welcome to AK APT LOGICS – Arduino Tutorial Series 🎥 In Part 4, learn how to use a push button with an active HIGH configuration and a pull-down resistor—a foundational digital electronics concept! See how to wire the circuit, handle input readings, and use the Serial Monitor to check button status in real time.
📖 Topics Covered What is an active high push button and why use pull-down resistors
Circuit wiring: breadboard, resistor, button, and Arduino UNO
How digitalRead() is used for input states
Live status feedback via Serial Monitor
Difference between pull-up and pull-down input logic
📌 Key Points about Push Button (Active High) Active high means the pin reads HIGH (1) when the button is pressed, LOW (0) when released
A pull-down resistor connects the input pin to ground (GND), keeping it LOW by default
Pressing the button connects the pin to Vcc (5V), overriding the pull-down—but releasing brings it back to LOW
Serial Monitor shows real-time button state and digital value
📌 Example Code c int pushButton = 9; int buttonState;
void loop() { buttonState = digitalRead(pushButton); if (buttonState == HIGH) { Serial.print("Push Button is Pressed and Value is equal to "); Serial.println(buttonState); // prints 1 } else { Serial.print("Push Button is not Pressed and Value is equal to "); Serial.println(buttonState); // prints 0 } delay(1); // short delay for stable serial output } 📌 Simulation/Circuit Details Button is wired to digital pin 9 and Vcc (5V)
Pull-down resistor sits between pin and GND
Button press results in pin = HIGH (1), no press is LOW (0)
Reference Images:
You can show your circuit diagram and simulation
📌 Serial Monitor Output text Push Button is not Pressed and Value is equal to 0 Push Button is Pressed and Value is equal to 1 ... 📌 Why Use Pull-Downs and Active High? Ensures precise input state, avoiding "floating" input errors
Provides stable default logic for input pins
Active high logic is widely used in switch detection and digital systems
📝 Problems for Practice Replace the pull-down resistor with Arduino’s internal pull-down (note: Arduino only has internal pull-ups natively—explain the difference)
Connect the button to a different pin and update the code
Show custom messages instead of numeric values
Add a second button for more advanced input logic and outputs
Challenge: Activate an LED only while the button is pressed

Lampu sensor suara Arduino adalah proyek yang mengontrol lampu (LED atau bohlam) menggunakan deteksi suara dengan bantuan mikrokontroler Arduino. Rangkaian ini menggunakan sensor suara untuk menangkap suara, seperti tepukan tangan, dan mengonversinya menjadi sinyal listrik untuk mengaktifkan relay atau langsung menyalakan lampu LED melalui pin digital Arduino.
Cara kerja dasar
Input suara:
Sensor suara mendeteksi suara di sekitarnya dan mengubahnya menjadi sinyal listrik analog atau digital.
Pemrosesan oleh Arduino:
Sinyal dari sensor dikirim ke Arduino. Arduino membaca sinyal ini, dan jika melebihi ambang batas tertentu, program akan mengaktifkan lampu.
Output ke lampu:
Arduino mengirimkan sinyal ke relay atau langsung ke LED untuk menyalakan atau mematikan lampu.
Komponen yang dibutuhkan
Arduino Uno: Otak dari sistem yang menjalankan kode program.
Sensor suara: Alat untuk mendeteksi suara. Sensor seperti KY-037 atau FC-04 umum digunakan.
Relay module: Berfungsi sebagai saklar otomatis untuk lampu AC yang lebih besar, menghidupkan dan mematikannya berdasarkan sinyal dari Arduino.
Lampu: Lampu LED atau bohlam AC yang akan dikontrol.
Kabel jumper: Untuk menghubungkan antar komponen.
Adaptor daya: Untuk menyuplai daya ke lampu, jika diperlukan (misalnya untuk lampu 12VDC).
Resistor: Digunakan untuk mengatur arus atau sebagai pembagi tegangan (tergantung skema, ada yang menggunakan resistor 10k ohm).
Langkah-langkah umum
Koneksi rangkaian:
Hubungkan pin VCC sensor suara ke pin 5V Arduino.
Hubungkan pin GND sensor suara ke pin GND Arduino.
Hubungkan pin output digital (DO) sensor suara ke pin digital Arduino (misalnya pin 2 atau pin 13).
Hubungkan relay ke Arduino sesuai dengan jenis relay yang digunakan (trigger low atau high).
Hubungkan lampu ke relay.
Program (Sketsa) Arduino:
Buka Arduino IDE dan tulis kode program untuk membaca input dari pin sensor suara.
Atur ambang batas (threshold) suara. Jika suara melebihi ambang batas, lakukan aksi tertentu (misalnya menyalakan LED atau mengaktifkan relay).
Unggah sketsa tersebut ke Arduino.
Pengujian:
Nyalakan Arduino dan berikan suara di dekat sensor (misalnya tepukan tangan) untuk menguji apakah lampu menyala sesuai program.
