used for selecting a highlighted on-screen keyboard key.
Programs are saved in the BrkProg_SAVE folder.
Once a program has been saved, you can access it with
the Load action. The Load action (i.e., an open folder icon)
is situated left of the Start block and directly above the
Save action icon. A loaded program will replace the
program that is currently in the Start screen.
Limited, but Not Limiting
After an initial inspection of the Brick Program app, you
might be tempted to throw up your hands and pull out the
PC for a return to real full-fledged EV3 programming.
However, there are two saving graces with the on-brick
programming interface: speed and convenience.
For example, if you want to test a motor or verify that
a sensor is functioning properly, a short linear test program
within the Brick Program app is a great solution. Likewise, if
you want to test the validity of a short logic branch, a series
of blocks can be quickly and easily laced together inside an
on-brick program for testing a scenario without investing a
lot of time in rewriting blocks of PC-based code.
On-brick programming isn’t really so primitive, after all.
In fact, this ability to create short tight program snippets
with the EV3 Brick will leave you wishing that other
microcontrollers enabled you to perform similar rapid
programming “sanity checks” on your next robot without
having to resort to pulling out the PC. SV
After the Color Sensor block has been added to your
program, you can configure its settings by pressing the
center button and scrolling through the color selections.
The color red has been selected in this example.
