Complete Guide: Connecting 16x2 LCD to Arduino
The 16x2 LCD display might seem intimidating with its 16 pins, but once you understand what each connection does and why it's needed, it becomes surprisingly straightforward. Let's build this connection step by step, understanding the logic behind each wire.
Delay vs Millis
Ever tried to make your Arduino do two things at once? Maybe blink an LED while reading a sensor, or respond to a button press while running a timed sequence? If you've been using delay(), you've probably hit the wall.
Fling - Not all who wander are lost
Fling revolutionizes mobile communication by creating an infrastructure-independent messaging and navigation system that transforms smartphones into sovereign communication devices capable of operating without cellular towers or internet connectivity. By integrating LoRa radio technology with smartphones through a compact companion device (The Ranger Node), Fling establishes a resilient mesh network where each node communicates directly up to 15km, with messages routing through intermediate devices to extend range indefinitely. NFC-based pairing eliminates setup complexity—users tap devices together to instantly exchange cryptographic keys and establish secure channels. Unlike conventional messengers that fail during natural disasters, in remote wilderness, or amid infrastructure failures, Fling maintains full functionality anywhere on Earth, providing text messaging, real-time location sharing, compass-based navigation to contacts, and offline waypoint tracking for backcountry navigation

Pomodoro Timer: My Arduino based focus tool
Pomodoro Technique, a time management tool that involves splitting work tasks into 25-minute intervals, known as pomodoros, with breaks scheduled in between each interval.
My TOP 4 Arduino Boards
With so many Arduino boards out there, picking the right one can be confusing. In this post, I break down my top 4 go-to boards: the reliable Uno, the powerful Uno R4, the wireless ESP32, and the sensor-packed Nano BLE Sense.
Redefining Alarm Clocks
Most alarms are designed to wake you up at a fixed time—regardless of what stage of sleep you're in. This can leave you feeling groggy and exhausted, even after a full night's rest. In this article, I share how I built a smarter alarm system that uses actigraphy to track sleep patterns and machine learning to find the perfect time to wake you up—when your body is ready.
