Use python and c programming language playing around on Raspberry Pi 3B
Lab1 - Lab5 : python GPIO control practice
Lab6 - Lab_final : OPCUA client/server and GPIO control together
Lab1 : Use GPIO to control LED
Lab2 : Make buzzer play the frequency recorded in json file
Lab3 : Use DHT11 sensor measure temperature and humidity
Lab4 : Record and recognize IR signal using json file
Lab5 : Passing data over bluetooth client/server service
Lab6 : Use open62541 library to create an OPCUA server
Lab7 : Control device. Add a method in OPCUA server that can control an LED(by callback function). Create a client that can call the method, making the LED change color, and monitor the status(color) of LED
Lab8 : Control device.
Lab9 : Manage device. Add object node LED and DHT11 and add methods and variable under each object
Lab_final : Use OpenCV to detect objects' color. Control Arduino robot arm to grasp objects to specified location according to their color. Use OPCUA server to record the history and current status. Client(app) can control stop/start of the process and monitor the variables.
