The Arduino programming course originally started in 2014 is being updated and extended. Updates include using the newest version of the Arduino IDE and updating the videos in the course to HD video.
Currently parts 1 to 5 of the course have been updated which cover Arduino sketch structure and flow, Arduino main loop, calling functions, variables, arithmetic operators and relational operators.
Once updates have been completed the course will be extended to include new material and topics. Take a look at the Arduino programming course contents page to see the currently available tutorial parts of the course.
