LEDSnapper: Open source LED Module For Arduino

[MarioGianota]

Hi all,

LED Snapper is a simple, open source, compact debugging tool for Arduino breadboard projects. It is suitable
for Arduino makers, because it is a 5 volt module.

If you are forever plugging LEDs and resistors into breadboards to monitor signal output from your
Arduino, then you may find this board useful. It plugs into your breadboard and there are 8 pins
connected to 5 mm LEDs which you can use to monitor signals. I call it LEDSnapper, because it snaps
into your breadboard.






The Gerber files and full instructions for building the board are available at: https://github.com/antic-ml/ledsnapper

Hope you like it.

Hello,

Although the LEDSnapper appears quite useless at first glance I actually like the idea!
For people with even a marginal amount of experience the task of plugging in some LEDs and resistors seems really easy, which it is, but I have introduced many people to Arduinos and breadboards and one of the common problems is that the leads of the LEDs and especially the resistors are all flapping around in the breeze - as Dave would say - and touching each other.

I took a look at your GitHub page which thankfully is nice and simple for beginners, but I do have some constructive comments towards that:
-I would add a couple of lines in the README.md about how to assemble the board and how to identify which leg of the LED should be connected to ground and maybe link in a good soldering tutorial.
-And remember, this is for pure beginners, they may not know what to do with a Gerber file and where/how to get these boards, I would add some information towards that end.

I considered opening a pull request on GitHub, but I don't have the time right now to write a nice explanation for the above.

I actually considered doing something similar a while back with DIP switches, but I don't think that there is a need for that.

PS: I really like your ENEMIESANDFRIENDS.md file

Hi Lary,

Exactly so: plugging in one, or two LEDs is no problem but when it comes to needing
more the breadboard tends to get a bit messy.

I updated the README.md file to include a "How To Build It" section.
Looks like I missed some obvious, vital information. Thanks
for the advice on what to include.

PS: ENEMIESANDFRIENDS.md. It is from a Hollywood movie. Steve Martin makes me laugh so much.

Good idea but that's already avaliable smaller from aliexpress for a couple of cents. Just as a hint I would prefer a module without common ground or vcc so that I'm flexible

Hi,

Yeah, I know. You can buy the module, plug it in and it just works. The point is for beginners to learn how to build their own PCBs
with a simple project.
