Mew 275 arduino project

On page 68 it states “ ensure modules are properly insulted “ Now i have killed a few modules, tortured even more but never have i insulted one ! Don’t you jst love typos 😂

Damned good article though and a remote control z axis has got me thinking i really need one of those ! I will also be following the cam grinder article with much interest as well.

Good article, but I'd take issue with the implication that you need to a geek to use a ProMini. The main difference is you have to use a soldering iron and preferably stripboard/pcb, but at the end of the day that makes it more reliable, the push in connectors on a Uno can easily get disturbed. Programming is exactly the same. I'm tending towards using a Nano for most things, it has solder pins but you don't need the plug in board for programming as you do with the ProMini, it works off the usb. Even that isn't too onerous, I've used quite a few and they work out cheaper

I thought it was good too, except the ProMini is 'retired'. Trying to start with one might amuse a beginner unnecessarily before he works out they're past their sell by date! Not as misleading as following the old book I have that recommends learning to drive in an Austin 7 but you get the idea.

In 2018 I'm using 4 different boards.

• Arduino Uno is the beginner friendly workhorse, 5V logic, no soldering required. Quite tough and suited to fat fingered experimentation as well as real work.
• Arduino Nano is electrically similar to the Uno but about 1/3rd the size and cheaper. Soldering required which can be a good or bad thing depending on what you're doing with it. Particularly useful for embedding in finished projects, avoid at all costs if you don't own a soldering iron.
• Arduino Mega has similar compute speed to the Uno & Nano but has much more memory and lots more Input-output pins. Good for larger projects, or if you want a GUI screen, but don't pay more for one if a Nano will do the same job.
• Arduino M0-Pro. Looks like a Uno but electrically completely different. Uses a 32-bit computer at least 3x faster than a Uno, has loads of memory, advanced input-output capabilities, and hardware debugging. Sounds marvellous (and is) but it costs more, uses 3V logic (meaning not so many plug and play modules are available), and - worst of all - it's electrically far more delicate than a Uno. Not harder to program and use, but relatively easy to damage. Mainly for advanced users and projects. At this level of microcontroller, there are boards outside the Arduino family that might be cheaper and/or more powerful or more suitable. I find the board useful as a way of staying with the comfy Arduino IDE rather than learning something more grown-up & complicated that I wouldn't often use.

Of these, I tend to use the Uno the most for real projects. Nano comes a close second, then Mega. The M0 is mostly experimental - I haven't found a project that actually needs a computer that powerful yet.

I typically stick with the nano because i picked up a heap of them cheap off ebay , all have header pins so I either solder wires to the header pins or use a screw terminal shield . You can also buy the chip with the bootloader and build your own .

Likewise, I have about 10 of the nano's from ebay....but also bought blank chips of various flavours where the 16k isnt needed or the physical size isnt needed....a programmer and some software sees them loaded with the bl...but I guess not everyone wants to go that far...

I tend to use a Uno and breadboard for development work once it is all working OK transfer to Pro Mini and either strip board or Printed Circuit Board. I use a UNO with the main chip removed to programme the mini. JC

Yes I bought a load of Pro Minis cheap on fleabay

I found these items shown in the latest EPE Magazine, they appear to add power control ability to Arduinos.

I know nothing about them personally but thought they might be of interest to people on this thread.

The look interesting ! Can’t say i have seen them before ,i wonder how long it will be before a clone show up on ebay ?
