[chbot] ESP8266 WIFI Internet of Things beginner...

[Daniel Powell]

The ESP8266 is a great little board but a little limited by IO and memory. I started with 8266’s but quickly progressed to the ESP32 (given my sloppy code and time critical usage). With an additional core, faster processors, more memory, BLE, still in a cheap format the ESP32 has become my go to micro.

I’m not the best electronically, have spent a great deal of wasted time trying to find issues either due to my ignorance of the way in which a controller works, a component works, or the Arduino IDE function. As such I’ve swayed to the M5Stack range of products which are cheap, encased, and tend to come prepackaged with a ton of additional components, Screens, switches, gyro, battery (and management), grove and USB are all part of the StickC. There are also a plethora of encased sensors, with sample code, that you can simply plug into the device, load the sample code and hack from there.

I run the M5StickC+, and Atom’s for a majority of my micro needs. I’ve a couple of core’s but they are only used for development. I note the stamp, but have not used it as of yet.

While the 8266 is a great learning platform, and brilliant in single simple task functions I was frustrated by it’s lack of IO and my sloppy coding creating timing issues on external serial IO.

The Arduino IDE is great for punching out code in reasonably simple projects. For me personally it gets confusing when you are attempting to complete complex tasks with multiple libraries. I tend to use the Arduino IDE (as it’s what I’m more familiar with) for fast and dirty code or simple projects. I use Visual Studio with Platform IO for anything large or complex where structure is important.

Given you are on a farm you may wish to look at ESPNow, 802.11 LR(long range) and perhaps LoRa.

Cheers,
Daniel.

Hi Team,
I’m looking to have a play with IOT, very much with learner plates on.
Just watched a getting started with IOT https://www.youtube.com/watch?v=UFCmTZUoZ1M<https://nam12.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DUFCmTZUoZ1M&data=05%7C01%7C%7C8e95064bc5cc4a0142a608da398e202f%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637885579842835065%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=3zc9eVLpVJSGh8RZPSnRksmv50bqQwyrPuHMERdVVm8%3D&reserved=0>
What board do people here recommend for having a play initially with WiFi on my farm?
These seem attractive price wise at $5 each landed, but are they OK or should I get something else?

Arduino IOT seems very simple for us non coders 😀
Looking to dip my toe in.

Mike
