Question
say_hello
dear community
At the beginning of my story I have to say, that this was my first time to IOT topic - and to the ESP32 and 8266
I'm a complete beginner, but one thing I have is the desire to known new technologies.
A month ago my colleague make presentation about #esp8266 and I was impressed this small board. So I decided that I would like to known more about #esp8266 and similar stuff.
I use Micropython (http://micropython.org/download) it is a firmware for the #esp8266 boards. At the beginning i have to underestand how it works, but I have read allmost a ton of webpages and articles about it.
some ideas regarding the aims:
What is needed for the car: We need to meet some conditions with the RC-car.
We ......:
- have the car expect one command every second. If it does not receive one, it stops.
- We can of course use the connection type that fits our existing hardware or use-case best. Once we have decided that, the search for a good connection library starts.
well - if i want to go with some web-app or pc controlled thing, then i should choose TCP/IP / WIFI or bluetooth ( with ESP 32)
regarding the hardware:
firstly: I would say that i should not make use of an Uno and an esp-01 module. This makes life much more difficult.
i think that i should choose a Wemos Mini D1 or a nodeMCU board. This will be smaller, cheaper and easier to use.
secondly perhaps i should choose a less old-fashioned motor driver than the 298. These will work well with 3.3V circuits,
be more efficient and maybe use fewer pins (which may be important when using the Wemos/nodeMCU). What do you think about this idea.
thirdly i think that i have to go with MicroPython: - it is a pretty intersting approach to stick - working with ESP8266 or ESP32
btw regarding the use of MicroPython i have found an interesting approach here:

How to build RC Car with the esp8266.
see the code https://github.com/dgolak/esp8266/blob/master/main.py
see https://github.com/dgolak/esp8266/blob/master/main.py
well i guess that this is a straingthforward approach...
cf: david golak:

How to build RC Car with the esp8266.
btw: my car has got a option of a steering axle - in other words - i have a slightly different car - than David has.
But that i think does not make a big difference.. I have to change the code at some places to fit.
i will have a closer look at this.
regards
