I am looking for an experienced Arduino C++ programmer who can help me get a personal project off the ground. I am new to this forum and Arduino programming. Still, I have a project idea that I wish to have someone experienced to determine the difficulty level of what I am considering and possibly assist in coding.
Some initial details of the project are as follows. I require ten units to be built (I would purchase all hardware necessary). Nine units are identical in every way, with the tenth unit being the same as the other nine, but also contains a color display. Each unit contains a Heltec ESP32 LoRa V3 processor and a GPS module (exact model TBD). As stated above, the tenth unit is identical to the other nine but in addition, contains one ESP32 Color Display. Each unit must be able to communicate with the other units at a line-of-sight range of around 2 miles (3.2 km).
If this sounds interesting to you and you have experience in Arduino C++, employing a simple communication protocol, GPS modules, and a color display, please contact me for more project details. Thank you in advance for reading this and considering this effort. Cheers.
Never used LoRa so not sure how effective it can be at those ranges or what extra hardware, eg larger Antenna, Power supply may be needed ?
A colour screen is easy enough, code wise, its more a case of how many free i/o you have on your finished project.
For a SPI screen you need a 4-6 i/o pins and 8 -10 pins if you want to use one with the Touch option, though there are some screens like the Nextions ( expensive) which use just 2 serial i/o pins.
