The Explorer is a great experimenter's platform for learning more about Arduinos and sensors! The board was a fun build, and worked well when completed. Adding the Expansion Pack provides more interesting projects. Issues I had were quickly resolved using Dr.Duino's Help page - just be sure to use the latest libraries (DrDuino_Explorer_Suite 1.0.4 or later) for trouble-free Expansion Pack use! I found a great project box for the combined Explorer & Expansion pack, at https://www.amazon.com/gp/product/B00X6DD4X8. The 5.6" x 6.7" x 3" box perfectly fits the Explorer board, which I mounted to the inside bottom of the box (standoffs provided in the kit work fine, with the right screws on the bottom). This leaves just enough room on the sides for wires and parts mounted through the sides. Either the Uno or the Nano should work fine in the box, with holes cut for cables and parts mounted as I've shown in my photo. Since the box is clear on all sides, you can see all the Explorer LEDs and panel display even with the lid closed. I mounted the servo on the bottom of the box below the board, and used the back side of the box for the "meter" - the servo fits underneath the board without interfering with the Uno mounting location. Any meter templates can be stacked in the back of the box - just pop the appropriate template for your current project to the front of the stack for the proper meter label! For the servo meter pointer needle, I created my own 3D printed pointer. If you have access to a 3D printer, this simple part can be printed using my 3D file, available for free download at https://www.thingiverse.com/thing:4460407. The pointer has a recess on the back for the servo horn, so just hot-glue it to the horn before pressing it onto the servo. Flip the lid open for easy access to all Explorer buttons, pots and headers, including the sound module, which I mounted on the lid with standoffs (see photo). I plan on mounting the PIR module on the lid also, but need to get some different standoffs - the mounting holes are very small. All this still leaves enough room in the box for the other Expansion Pack electronic components, for a complete storage solution. Now looking forward to building and testing my own unique projects! Great job, Dr. Duino!
Once you realize that the instructions are online - step by step - and you need to reference them online, everything went real smooth! Steps were very clear and easy to follow. Built two of them and all worked. The test sketch was an added bonus! Lack of notes for linux (get a raspberry-pi - because it's cool tech too!) only reason not 100% great. I just ignored the driver download, and ignored windows paths. Would recommend to anyone wanting a easy test platform with the most common components at the ready!
The board is well laid out. With logical and intuitive functions. The board itself is professional grade using plate through holes, and silk screening. It is easy to solder without creating problems. The assembly process is well organized so that things are installed before something else makes access to that area a problem. The only problem I had was with the instructions. I wish I had a way to provide feedback as I was doing the assembly. Since I did not take notes, I am not able to help you correct the minor issues I worked through. Most issues are things like you say I need 7 resisters and then say install these 5 resisters. The drawing makes it clear what to do, so no big deal. I did have a problem with the installation of the IDE, specifically with the DrDuino software as the instructions did not give enough information. I had to know what to do and did not have the experience at that point to be successful the first go around. I had a problem with the ATP sketch being too large for the NANO. After a bit of trying to figure out what I might have done wrong, I used the help button to send an email. I received a response very quickly. More importantly, the solution was quickly made available and with a bit of hand holding thrown, allowed me to resolve the problem and be successful in record time.
Very Nice project, and it only had taken me about 1 day to build. I makes it very fast to change the different Hardware and Software coding, with out having to worry about if any of the jumper wires are connected up correctly.
Another excellent product! Very high quality, impressed with 1% resistors, extras included in kit are a bonus for me. Most difficulties are of my own, for my ears hearing the buzzer was a problem. A few changes in values in buzzer code from examples proved it was working correctly. For myself working with instructions on screen is a rather new experience but works once I got used to it. Kudos to Dr Duino for his nice response to a few errors I did locate, my background and experience allowed me to figure out what was correct but might have slowed down someone with less hardware experience. Re-reading instructions, looking at previous instructions and it should become obvious what the correct action was. Overall a fun activity this being the third project from him.
Very useful for rapid Arduino prototyping! All features worked first time! Made a few improvements: Substituted 10k pots with knobs; mounted a DC regulator input barrel connector on back; added pins to convenience area breakouts. A little red header jumper now makes it easy to power the whole board from the regulator, if desired, and only once one has adjusted (and doublechecked) its output to 5V. Dr.Duino's created a worthy successor to his original UNO-powered Dr.Duino!
