Experimentation's with a TelegramBot polling an ESP32.

These Bots can be found or created via the Telegram App Messaging service...

(in our case I have called it "MRLbot" )

MRLbot & ESP32 Marriage possibilities :-

Proportional, Integral and Derivative or PID control systems have been around for a very long time, but they are still not very well understood.

Recently I convinced Fred to give a bit of a talk on the subject.
Good thing with robots, is convincingthem is just a case of programming them :-)

Here is the video of Fred's presentation.

I just bought one of these, thought I would bring to your attention :-

Best part ..... its circa 120$ delivered including two x1/x10 probes ..

(-: bonus for me was that the customs elves were on coffee break :-)

In a nut shell its a Dual channel 100Mhz with 7" colour touch screen.

The performance drops off the more you lean over 80Mhz. (100Mhz is bit tongue in cheek, however how often do we need to measure so high)

Ahoy !..

I was rather dismayed when I saw my Mega attach with an Arduino service and I got a endless
error 

Saw Ray post this - to me looks like a nice mini Boston Dynamics Nightmare ... very nice

This is an interesting series about designing a walking robot. https://www.youtube.com/playlist?list=PLpwJoq86vov-C5SldDA-AhxesVHPRk74x  most of this is above my head, but might be useful to Ray in his newest challenge.

Here's a quick mock-up of the RasPi service UI.
Having a pin out reference I always find useful ...  can prevent blue smoke sometimes :)
Alexinator40 and Ray have been suggesting a generalized I2C interface.  I think components from the Serial service can provide a UI which allows for generalized reads and writes to devices on an I2C bus.
The buttons on the right would be just to read and write GPIO pins..
