Hi Arnoud and others, The Mega has 15 PWM outputs I didn't know that... until yesterday! (Mega newbie.) So you helped me solve two problems at once: 1) I was using port 13 as PWM, but this is the LED port and will always flash briefly during boot -- at least with the default bootloader. Easy, I'm us...

Hi again, Now it occurred to me, maybe the TB6612FNG has dedicated PWM (not sure, never used it). This can be nice so the Mega PWM outputs may be used for other stuff like servo control. Anyway PWM is working quite well with the DRV8833s. I still have lots of testing ahead, let's see if my controlle...

Hi Arnoud / everyone,

Answers to Arnoud's post are in the Mega controller thread, please go there.

Thanks,

Rubem

Hi Arnoud, Thanks for your answer. Yes, the Due is cool. There are also other boards with ESP8266 / ARM Cortex-M3, etc. But I don't think speed will be a problem soon. You guessed right, I use I2C a lot, my displays already have / will have their own dedicated Minis / Pro Micros so part of the heavy...

Wow, amazing / wunderbar!!!

I forgot, the proto shield underside looks like this for now:

Hallo allerseits, Ich baue meinen eigenen Controller für ein komplexes Projekt und dachte, es wäre am besten, einen neuen Thread zu erstellen . mega-shield-ft.jpg Es ist ein Arduino Mega-Klon mit einem Prototyp-Schild an der Spitze. Der Schild erhielt ein DFPlayer Mini MP3-Modul plus 3 duale DRV8833...

(Deutsche Übersetzung im nächsten Post) Hi everyone, I'm building my own controller for a complex project and I thought it would be best to create a new thread. mega-shield-ft.jpg It is an Arduino Mega clone with a prototype shield on top. The shield received a DFPlayer Mini MP3 module plus 3 dual D...

Hi everyone / Hallo allerseits, I once used this some time ago for a test. It is called "nylon transistor spacer" or "transistor washer" and sold in batches. The rim diameter is 8 mm, sleeve 4 mm, hole 3 mm. (Google Translate) Ich habe das vor einiger Zeit einmal für einen Test verwendet. Es wird "N...

Hi again, Inspired by Karl's thread I purchased some HC-020K encoders (see my post here ) and they were the best option, so precision is finally good. Regarding the controller... Florian (atzensepp) hinted me to go for an Arduino Mega instead of expanders. I finally decided to give the idea a try, s...

Hi Florian, Und hier noch mal 2 weitere Motoren. Der Rote ist ein alter gebrauchter Encoder-Motor. Der Schwarze ein Neuer (soll kräftiger sein). Your pictures make it clear why the new TXT motors perform so much better than the old TX ones. The motors are a lot bigger... ----------------------------...

Hello Karl and others / Hallo Karl und andere, (Deutsche Übersetzung folgt) I was inspired by your post, these fork encoders were just what I needed for my project so I purchased some. I wanted to mount the sensors preferably without parts modding, so it took me quite a while to figure out a way to ...

Hi Holger, Den freien Download vom Movie Maker hat Microsoft abgeschafft. True. Microsoft recommends Clipchamp Free as a replacement. It's easy to use, it's what I use for my ft videos. ---------------- Google translate Wahr / richtig (?). Microsoft empfiehlt Clipchamp Free als Ersatz. Es ist einfac...

Hi everyone, I've made an important change in my setup so that a magnet and reed switch have replaced the color sensor as you can see below. I also made several ajustments to the Arduino program (special thanks to Juh :D who kindly sent me his ideas and code) and the combined result is that precisio...

Hi Jan / Uffi, Many thanks for your help, I've made a few changes as per your suggestions. I've removed the initial states of the state machine so now it just waits, senses the yellow plate, counts some steps, then stops. Removing interrupts and using delays in the main loop does ideed seem to incre...

Hi again, My two POCs are shown below. The mechanics of both models are identical: An encoder motor with a Z10 pinion that drives a Z40 (32 teeth at 90°) which rotates a turntable with 6 spokes. One of them has a yellow plate acting as a marker for a luminosity sensor. poc.jpg 1) The right POC uses ...

What prompts did you use to get this?
dt: Welche Anfrage hat dieses Gedicht generiert?

The prompt was:

"Write a short humorous poem about me having to deal with different and possibly unknown red hues each time I buy a new fischertechnik kit."

Hi, Maybe there are different versions of the Robotics Competition Set , I'm not sure. But there are some items not listed in ftdb, you can confirm this looking at the photo and this document . I've noted the following differences: Items not indexed in ftdb: - 159055 Robotics Competition Set manual ...

Here is a new poem I just made with ChatGPT about something that was in my head. (Apologies, my German friends... translating wouldn't work here)

"A new poem ChatGPT made for me" would be more appropriate...

Hi, Here is a new poem I just made with ChatGPT about something that was in my head. (Apologies, my German friends... translating wouldn't work here) Oh dear, oh dear, what a plight, Buying fischertechnik kits is just not right, For every time you open one anew, A sea of reds floods your view.
