Description
Description:-
The project is Robotic-arm controlled by a mobile application known as BLYNK; it is free and easy to use for automation and IoT projects for beginners. In this project, multiple servo control different axes and rotation of the arm in a different direction. This project can be used where human intervention is not possible, it can attach to a remote-controlled rover. It can carry radioactive stuff, turn on-off the switch, carry a light load, push-pull lever.
Project Used Hardware
NodeMCU, servo motors
Project Used Software
ArduinoIDE, BLYNK
