Non-programmer here. I’ve long desired to program Arduino microcontrollers but haven’t had the ability and/or the patience to learn programming. I’m a very visual person and get confused if I have to keep more than a few lines of code in my head. Even if I understand how I want a signal to be processed into an action, when the flow chart in my head needs to be translated into text I get overwhelmed.

A solution arrived for me in the form of a number of visual arduino IDEs. Flprog, Outseal, and Open PLC. They all allow programming in ladder logic, and Flprog and Open PLC allows for function block programming. Ladder logic is useful for many tasks involving discrete I/O (Ex. A button latches a contact which turns on a relay which turns off a light and turns on a motor.) Function block programming has enabled me to perform more complicated functions like creating an HMI using a menu system displayed on an LCD connected via I2C. These are tasks that I wouldn’t have a chance of accomplishing without the complex arduino code being contained in graphical functions blocks which I can wire together and configure with a gui.

Prior to compilation, Flprog displays the raw arduino code in the arduino IDE, which gives me a chance to exam the actual code produced by my function block program. I find it to be very educational.

As a non-programmer, I have no idea if this embedded programming use case can be generalized to more complex programming tasks, but for my limited use case it’s been transformational.
