@martinayotte
Light up some candles, maybe it will arrive in 4 weeks :-)
Stavros Korokithakis
@skorokithakis
set it down, bam, smoke
haha
i have a shrine :P
@martinayotte another issue is that the esp was getting disconnected from the wifi a lot
could it be interference from the motor?
Martin Ayotte
@martinayotte
I don't know ... maybe glitch on power. try adding more caps.
tzapu
@tzapu
i don t think i ve ever seen a discussion related to building something aroudn the ESP where more caps was not mentioned… moooore caps :P
Stavros Korokithakis
@skorokithakis
hahaha yes
hmm it might have been a power glitch, good call
thanks
the good thing about that is that it has a power supply by itself
so you give it 9v and it gives you 5 back, which his well in range of the ldo
Martin Ayotte
@martinayotte
Yes, If you remember, that was the one I've suggested 2 months ago, but at that time, you felt it was a bit too big.
Stavros Korokithakis
@skorokithakis
did i? well, sucks to be me :(
Ivan Kravets
@ivankravets
@tzapu of course, you should add #include <Arduino.h> on the top of file if use Arduino framework
Stavros Korokithakis
@skorokithakis
@martinayotte oh, it was because the one i got could drive two motors, i didn't notice the amperage
but now that i see how this one works, it's clear that the one you suggested can drive two motors as well
Ivan Kravets
@ivankravets
@tzapu also don't forget that if you add library manually or install via Arduino IDE Library Manager you need perform Menu: PlatformIO > Rebuild C/C++ Project Index. If you use PlatformIO IDE and PlatformIO Library Manager within it - PlatformIO monitors places where new libs could be added and update the project automatically for you
Stavros Korokithakis
@skorokithakis
hmm, i'm not even sure what the voltage on these motors is
the battery pack looks like four pairs of AA batteries in series
hm
Baruch Even
@baruch
Add a start callback for HTTP updater #1817
Stavros Korokithakis
@skorokithakis
oh it does say 9.6v
Baruch Even
@baruch
BTW, who is doing the merges of the pull requests?
tzapu
@tzapu
thanks @ivankravets did all that, i was just wondering on the arduino h , as i never included it before. cheers, compiled and uploaded a project, tis nice
Stavros Korokithakis
@skorokithakis
hmm, i'm getting an error on the min and maxfunctions, what's the right name to use?
ah, std::min and std::max
Martin Ayotte
@martinayotte
There is a conflict if I remember with <std>. In Arduino.h, to workaround the issue, there are macros _min/_max .
Stavros Korokithakis
@skorokithakis
ah, thanks

@Makuna
@skorokithakis You are better off using a RC speed controller and just use the Servo library to talk to that.
Stavros Korokithakis
@skorokithakis
@Makuna what's an RC speed controller?
oh, a complete black box?
Stavros Korokithakis
@skorokithakis
oh that looks great
what does it do? same as the h-bridge i bought?
Michael Miller
@Makuna
Yes, but they are smart. This one has brake but no reverse, if you need reverse, just search for one with reverse.
They take a standard hobby Servo input and use that to control the voltage on the DC output, including the ability to reverse (if it has the option).
Some of these have actually ATMEL AVRs in them, and can be programmed with Arduino ;-) But it is sort of a hack.
Stavros Korokithakis
@skorokithakis
oh hmm
yeah, i need one with reverse.. let me look
hmm, i'm not familiar with these... do i need 20 amps?
Stavros Korokithakis
@skorokithakis
@Makuna any ideas? i'm completely lost with these
Michael Miller
@Makuna
What size is the motor?
Stavros Korokithakis
@skorokithakis
no idea :/ this is a car i've had for 20 years
Michael Miller
@Makuna
What RC car is it?
Stavros Korokithakis
@skorokithakis
just dug it up and figured i'd stick an ESP on it
Michael Miller
@Makuna
1/10th scale? Toy?
Stavros Korokithakis
@skorokithakis
great question
