Things used in this project Hardware components Arduino Nano R3 × 1 Ultrasonic Sensor – HC-SR04 (Generic) × 1 Software apps and online services Arduino IDE Hand tools and fabrication machines Soldering iron (generic) Story “Collision Avoidance System for Drones”, as the name suggests, protects the drone from collision from any obstacle such as a wall.In day to day life we hear drone crashes which not even cause machine loss as well as a great threat to peoples around. As drones are becoming common these days so it increases the threat of drone failures. So I designed this collision avoidance system to protect people as well as machine loss. The idea behind the project is too simple. Whenever any obstacle is detected from left side the drone must drift towards right and same in all four directions. By keeping everything really simple I just manipulated the receiver’s signals which are…

To program NodeMCU in Arduino IDE, we have to install esp8266 board (ESP8266 core for Arduino) to Arduino IDE. Add Additional Board Manager URL for ESP8266 board:> File > Preference Add “http://arduino.esp8266.com/stable/package_esp8266com_index.json” in Additional Board Manager URLs. Add ESP8266 board to Arduino IDE:– Open Boards Manager in Arduino IDE– Search “esp8266” or “NodeMCU”, you will find “esp8266 by ESP8266 Community”. Install it. That’s it
