Arduino Experimental Board (extension)

thingiverse

This is my approach to master Arduino. A design (arduino_breadboard.stl) was sourced from Thingiverse. I give credit to the ingenious creator superwoodle for "Arduino w/Breadboard Holder", licensed under the Creative Commons - Attribution license; Thingiverse thing:1190968. I designed several components that integrate into a comprehensive experimental board. Prewiring two potentiometers and one switch is possible (see right side). The board is already grounded, so all I need to do is connect +5V from Arduino and "S" like Signal for Inputs of the Arduino. Same with the switch. This setup makes it easier to handle, nicer to see and less to wire up. Incorporating a small Voltmeter (see left side) is also possible, just a heads-up. Two LEDs can be added as well. The board is already grounded, pre-resistored, so all I need to do is connect one wire to light it up. This makes it easy to use. You end up in such gadgets if you have too much free time on your hands. But others appreciate this little helper. It makes Arduino learning a bit more enjoyable, or not.
