digital to analog 5v
Thanks for the replies everyone.
Sorry should have been more specific with my signal requirements:
I think the main requirement for voltage signal is stability and accuracy.
It would be use as the voltage reference of a lab power supply to control its output voltage and...
how to generate an analog signal
Hello,
I am trying to build a circuit that can output a 0-5V analog signal.
This analog signal will be controlled by a mcu.
What i have in mind is to have a mcu communicate to some sort of 12bit dac.
I am familiar with the mcu portion of things, but i am not...
Hello,
With regards to mp3 player circuit.
Try looking at this website. **broken link removed**
You can buy the DIY mp3 player as a kit or assembled. The nice thing is that evrything is provided, schematics, source code everything. So i guess its a good way to learn ;-)
You can download the...
Hello,
You may find this link useful https://web51.hw-server.com/links.html
It contains links of projects, connecting 8bit controllers to the ethernet.
Re: Energy meter
Hi i remembered the analog device website had a reference design using the ade7756.
Also do watch out for the phase shift of the CT, could be a problem if selection is not good.
switch debouncer ic delay
can you add capacitors to the switch? or do some sort of software debouncing?
Also maybe this article can be of use? h**p://www.ganssle.com/debouncing.pdf

To be frank i started working more indept into c lately Found the K&R to be extremely useful. thats my first reference. anything else just google for it :-)
Pointers are a little hard tp gasp. Currently I am finding difficulties in pointers to function.
think c is still mainly used in mcu...
Hello,
I have a question on transformer selection for liner voltage regulator type powersupply circuit.
What is VA rating for a transformer? Is it true that if the VA is too big the transformer will heat up and waste alot of energy?
I setting up a ps circuit using 7805, 5V output about...
usually youcan find examples from microchip, ti that use the mcu to do the job of calculating total power and kw/hr consumption. but its usually single phase. just improvise to 3 channels. but really for a quick fix the analog device ics would do. and it comes in 3 phase variants too :-)
