Thanks Robert. An interesting experiment! The BBCode came out fine. Why don't you mail this through to the editor, it may be useful to other readers in the letters or Q&A.
Thanks for taking the time to do this and for sharing!
Cheers
Andrew

Re: Lithium battery with no cell sensing for charge monitori
Hi
Looks interesting but seemed like it still needed some kind of charge management?

Re: Beyond Arduino - What should I cover next?
Hi Robert You're correct on the simulation - it has no hardware inputs, and therefore no readings. You can simulate button presses etc. within the simulator by changing the register values. A debugger is what you really would need - I use an Atmel ICE basic, and it does the trick. Alternatively, if ...

Re: Beyond The Arduino 3 - Guessing Game
Thanks, Robert, for sharing. It's interesting to see an experiment that validates the info on the datasheet. I don't know enough of the details of the innards of the ATmega328, but I do know that the ADC uses a "sample and hold" circuit - this "grabs" the input voltage, and then ...

Re: Beyond Arduino - What should I cover next?
Great, thanks @robralston. Great idea on the debugging, and I'm working on an I2C article at the moment so should have that out in the August edition. Debugging and simulation are useful tools, so will definitely add to the list! Pleased you solved your problem with the guessing game. Embedded syste...

Re: Beyond Arduino - What should I cover next?
Hey Casey
Great! Thanks for the background - funny how you can talk to the most hardened embedded developers, and they still love working with LEDs!
The PoV and LED matrices is a great idea - thanks. Could include it in an article on shift registers and charlieplexing maybe.
Cheers

Re: Serious toy coming... Can you spare $9 ?
This looks great, particularly the price point - although if you plan to do more than embed it in a project it seems you need to buy add-ons to make it really useful. I was really tempted, but then thought it would end up in the same drawer as my PCDuino, Raspberry Pi, etc...

Re: R2 D2 new cousin...
That's pretty impressive - particularly since the "head" doesn't remain vertically above the ball, but can move down from the centre of gravity.

Beyond Arduino - What should I cover next?
Hi! I'm really enjoying writing the "Beyond Arduino" series of articles - part 4 is just out in the June edition. I've had some great feedback (and suggestions) from readers, and would love to hear your thoughts as well. So far we've covered the breadboarding of an MCU, the move to Atmel S...

Re: Maglite Flashlight Policy Changes
Not sure about in other parts of the world, but here in SA the Maglights have been surpassed by the LED Lenser brand. I love my old Maglight, but can't deny that the my LED Lenser has the edge on the Maglight.

Re: Beyond the Arduino - AVR article
Yes, now I understand the difference between (0<<3) or ~(1<<3). I appreciate your answering questions; I'm going to have a lot of them. Reading the data sheet raises many questions. Those datasheets! Happy to help, it takes a while to start thinking like someone who spends a living writing datashee...

Re: Beyond the Arduino - AVR article
Thank you for the articles. Been having trouble getting into Atmel Studio. You paved the way Excellent! It's not that hard once you get stuck in, and so much more flexibility and control. I'd never go back :cool: Bought an AVRISPmkII from Atmel but didn’t pay attention to the shipping costs so I re...

Re: Beyond the Arduino - AVR article
Thanks for the interest in the series @Selmaware. I should have been clearer on the bootloader. @dacflyer is right, you can either buy an ATmega328P with a bootloader already loaded (or use the microcontroller from your Arduino UNO), or burn the bootloader onto a new ATmega328P. I had put together a...
