This kit was originally designed to be used for building a digital speedometer for a In conjunction with the adafruit ultimate gps breakout, I created this project. I put the kit together and soldered everything down in about two minutes, and I hooked it up in less than a minute. It took me about five minutes to set up and run the example sketch. I spent another day or two writing the tinygpsplus and adafruit libraries to get a custom sketch the way I wanted it. With the Adafruit libraries, I was able to drive the display and adjust settings on the GPS chip, and with tinygpsplus to parse the NMEA data. I will make sure the gps speedometer works perfectly when I get it. You can see your direction by using the asterix in the center of the first display the first decimal point in the first display provides satellite fix information and the last three displays show your If you don't like truncated 3's or 5's, then you might want to edit the display code a bit. If you'd like a more traditional 7-Day plan, click here Styles 3 and 5 of the LED backpack display are editable. The text at line 106 should be changed A change to line 108 should be made to 0b0000000011001111 A second one has since been purchased in order to construct a tachometer for the bike. I have since built a digital tachometer with this display.
With the Adafruit backpack library, it is extremely easy to use. It was combined with an Arduino nano and a rotary encoder to make an Alpha Numeric Display. It is much easier to control multiple separate segment displays with an IC2 address, rather than individually with a IR remote.
Other reviewers have even provided Arduino libraries for these boards. You can scan your i2c bus until you find the correct address settings if the libraries you have aren't the right ones. You can check the wiring if you do not see anything. For Arduino enthusiasts, that's all there is to it. The product is everything that it says it is, and assembly couldn't be easier. In my experience, I've ordered a few of these at different times and the brightness remains the same across all of them at the same voltage level. Because it's interchangeable, I can order a new one, take one out of a drawer, or rip two out of an old project, knowing that they will all look good *I have attached a photo of a couple units in action before they went public Here is my post-assembly of a little thermometer / clock I made.
You can easily follow the Adafruit examples to use this. The only thing that's not so great is It's NOT a big deal, but it's easily One disadvantage of the Adafruit style number fonts is that they can appear Although the number 5 has a strange look (they did that to make it look like it isn't uppercase S), they must have been trying to achieve something. Some people may also not like the zero style, as it is a slash style. This is how the problem can be solved The driver code is edited, then you find the uppercase S and O and copy the bitmaps It is either or. The C++ source code). In order to illustrate how this looks in action, I've attached some photos of my project and prototype board. There is a project I am working on that uses both numeric and alpha displays, as you can see in my pictures. It is important to note that the red displays are quite If you choose to use the lowest brightness, it may still be too bright, so you may wish to use it behind a red plastic filter.
In addition to using a rangefinder, I use this to display distance These are the two digits that represent the display and the two that represent the "in". It is very easy to program the display. There is a library code that can be modified easily. It has adjustable brightness, and can be set to blink (I have it blink if the range is too short for precise adjustments to be made). The 7-inch screen will be my next purchase There are segment versions, and generic boards from Adafruit, and maybe one or two more of them.
I was able to get the adafruit library to work as expected. Creating Rick and Morty portal guns.
Possibly a little lighter on the red than it should be. This one is more of a burgundy There was an orange color to it, kind of like tomatoes before they were ready to eat. This was disappointing, as I purchased it for use as a tail light on my bicycle. It still works, but was not what I had hoped.
As a pain in the neck to solder, I ruined the one I bought! It would be nice if there was one that came with it A soldered connection represents a one-way connection.
