 ඔයාල කලින් Arduino වලින් Knight Rider Bulb System එකක් හැදුවා මතක ඇති. අද අපි Theft Alarm Indicator එකක් සරලව Arduino වලින් හදමු.  කොහොමද මේ Theft Alarm Indicator එක වැඩ කරන්නේ?      අපි මේ Arduino පරිපතයට දුර මැනගන්න පුලුවන් වෙන විදියට sensor එකක් ( HC-SR04 Ultrasonic Sensor) සෙට් කරනව. ඒ සංවේදකයේ නියමිත දුරක් ලබාදීලා ඒ දුර ප්‍රමාණය අඩු උනොත් තමයි Alarm එක ක්‍රියාත්මක වෙන්නෙ. HC-SR04 Ultrasonic Sensor එක ගැන දැනගමු.      HC-SR04 Ultrasonic Sensor එක සෝනාර් භාවිතයෙන් වස්තුවකට ඇති දුර හඳුනා ගැනීම සඳහා භාවිතා කරන සංවේදකයක්. ඕනෑම රොබෝ විද්‍යාත්මක ව්‍යාපෘති සඳහා එය ඉතා යෝග්‍ය වෙනවා. 2cm - 400 cm අතර දුරින් ඇති ඕනම වස්තුවක් හඳුනා ගන්න මේ Sensor එකට පුලුවන්.😯   Simple Robot Created by using HC-SR04 Ultrasonic Sensor       HC-SR04 Ultrasonic Sensor Pinout Details ☑️ VCC Pin - මේ pin එකෙන් තමයි  sensor එකට අවශ්‍ය බලය ලබාදෙන්නේ. Arduino board එකෙ 5V pin එකට සම්බන්ධ කරයි. ☑️ Trig Pin - Ultrasonic ශබ්ද තරංග නිපදවීම සඳහා Transmitter එකට  අවශ්‍ය තොරතුරු සපයන pin එක තමයි මේ Trig Pin එක. Arduino b

Begining with GitHub

Image
  GitHub is a website and cloud-based service that helps developers store and manage their code, as well as track and control changes to their code. To understand exactly what GitHub is, you need to know two connected principles: Version control Git In this article, I’ll first explain those two principles. Then, we’ll dig into more about GitHub and how you can actually use GitHub to your works. What Is Version Control? Version control helps developers track and manage changes to a software project’s code. As a software project grows, version control becomes essential. Take WordPress… At this point, WordPress is a pretty big project. If a core developer wanted to work on one specific part of the WordPress codebase, it wouldn’t be safe or efficient to have them directly edit the “official” source code. Instead, version control lets developers safely work through branching and merging . With branching , a developer duplicates part of the source code (called the repository )
