Q: The internal chips are visible. It seems that it is not wrapped and has no cover.. Is that dangerous when inserting it into the computer? You might get electrocuted!

mesco64 L’articolo è mostrato fedelmente a come verrà spedito, ossia privo di involucro. Nel mio caso l’involucro l’avevo da una pen drive simile che mi si è rotta.

Consider I'm a beginner, I'm doing my first projects with these modules and the Arduino UNO board. I had to investigate a lot about how to use but in the end it worked perfectly. Connecting to my home's wifi worked at the first attempt and the Blynk setup showed it online inmediately, You must add a jumper in order to upload your sketches from Arduino IDE. The jumper is needed at reset time (when you insert on a pc, or power up), to enter the correct mode (running or flashing). To run the sketch you remove the jumper and re-insert on the USB port. I had some difficulties with the baud rate on the serial port. On Windows 10 I had to install a driver but then on the device (COM4 for me) properties I had to fiddle with the baud rate to make it match the module's. I love how tiny this module (ESP8266) is, keep in mind that it uses 3.3 V so you should put resistors when connecting Arduino UNO pins to the ESP8266. The USB adapter is great, works perfectly and avoids you to mess with Arduino UNO for uploading sketches or monitoring debug messages from the serial port. I chose this model to save money but it has a very very limited number of IO pins, so it's perfect to get wifi connectivity, specially on IoT projects. Spending a bit more you can get modules with many IO pins, if that's the requirement. The USB adapter is needed only when connecting to the pc (upload, debug) otherwise the module is independent, you have only to ensure a correct power supply (3.3V).

Aggódtam, hogy hogy fog egyben ideárni, de egy masszív kis műanyag dobozba van csomagolva, így sérülésmentesen megérkezett.

Q: My drone has the front lights red and back light are blue which is confusing, is that normal? My E57 mini drone from Eachine too, has it opposite?

demandé par Höddi sur 2019-11-11 09:53:05

mesco64 Yes, that’s normal, once it was useful to understand drone orientation, today it’s not needed anymore

This kit is great for beginners but there are NO INSTRUCTIONS AT ALL. The package is carton made but it's ok for the price. The projects I've built so far (three) have worked perfectly. All the components have a perfect finish and look. I tested the controller, the breadboards, some buttons and the LED numeric displays. I would have liked to get more jumpers (male to female) and some resistors (in the kit were four types: 220, 330, 1K and 10K), all things that I will order soon. The battery holder IS IN TRUTH a box to keep resistors or small parts in an orderly manner. If you need a battery box you must buy separately. I'm not sure that all the parts are what they should, and there are some tiny components I still haven't identified. It would be nice If they gived a link to a technical sheet FOR THE KIT (list of all the component's with photo, part code and part name). In any case I recommend it!

mesco64 It was hard to find tutorials on the spare flame sensor included in this kit (analog, not on a module) this is the only source I've found so far: https://www.youtube.com/watch?v=RFjDsrc-8Dc
