61  Using Arduino / Project Guidance / Re: simple break beam circuit using https://www.sparkfun.com/products/241 on: June 27, 2014, 12:43:25 pm
I have to say that some 45 ish years ago I was given my very first electronic kit. No ICs all discrete components. I build my very first radio set at the age of 9. I achieved all this without the need to be able to read schematics or understand the finer points of electronics. I did have a resister colour chart to help me pick the correct value resistors and some drawings to help me identify the legs of the transistors. I would like to think that this exercise has not "crippled" my progress but rather it whetted my interest in electronics in a way I could understand that has lead me to where I am now. At the time of building my radio I had Zero electronic theory. I am still learning 45 years later.

Take a look at fritzing .... breadboard layout .. I rest my case.

But then I may just be the odd one out.

Cheers Pete.



I realize you are new to electronics but I feel compelled to tell you that you are crippling yourself by putting your project as a higher priority than learning how to read and draw schematics. In my opinion, doing electronics projects without knowing how to read and draw schematics is counter-productive and just results in more problems , either in trying to communicate with us as you are now or in circuits not working.

Hacking is certainly a fun and exciting way to learn, that keeps you engaged making and thus motivating. You can learn as you need as you go. I mostly learn this way myself.

The Ethos of Arduino is to bring electronic building to the masses by "plugging" in shields and sensors with little knowledge on how they work internally.

For my sins I also play base guitar, I have never read a music theory book but I can tell a bum note when  I hear one smiley and I leaned to play a stomping walking blues riff by trial end error. Iteration through mistakes is a fun way to learn. I will never be a session musician but i am still having "fun"

Cheers Pete.

Or if you are wanting to turn the Arduino back on after a fixed amount of time the use a 555 timer as a pulse stretcher triggered from the Arduino to cut the power to the Arduino and WIFI shield until nnn time has elapsed then turn it back on again.

See lots of ways to do it smiley

If you are using a PWM signal then any Radio Control Electronic Speed Controller will  (ESC) do the job for you.

They are used in RC cars and quad copters to control the speed and direction of motors based on a radio transmitted PWM signal

You can if you want to use an Arduino, but why ? when it has already been invented.

something like this perhaps http://www.ebay.co.uk/itm/261414605285

OK I am not sure i understand this but if i do then no,  you cant do it !

If the unit is OFF then is is not able to run any firmware to turn itself back on again.

What you need to be doing is turning the power to the WIFI shield OFF putting the Arduino into sleep mode. You can then use the WDT or some external interrupt to bring it back to life again. You will of course have to get the WIFI card to re-connect etc.

Hi have you tried this application

https://play.google.com/store/apps/details?id=slickdevlabs.apps.usbtoserialterm&hl=en


I have used it with the FTDI USB->Serial cable without any problems.

Cheers Pete.

I live in France and my wife ans a brand new overlocker tat she is looking to put to good use.

PM me with your requirements and if France is not too far then let i will give you an idea of time and cost.

Cheers Pete.

Hi Jack,

I can certainly help you with this programming and interfacing task. I am a former toolmaker and so understand your mechanical requirments and am able to translate them into a program to do the job.

What is your timescale for this project and what is your budget.

You can see some of my other work at WWW.EmbeddedAT.com If you think I am a good fit  four your need then please drop me an email to Peter@EmbeddedAT.com

Cheers Pete.

Glad you got it working smiley

Hello,

I have working experience in both BLE and IMUs although not using those modules. They are very expensive for what you are doing.

If you give me more information about what it is you are trying to do with them then I can offer advice.

Cheers Pete.
72  Community / Gigs and Collaborations / Re: Looking for someone to write a menu based on m2tklib. on: June 17, 2014, 04:22:59 pm
What you are describing here is not a menu it is a full blown UI with changing inputs etc. over several screens.

cool my Sons are both musicians too.
One produces music in London, the other is studying for a degree in music in South Wales

I may be interested but you need to offer some more information at to what it is you are planning on doing.

Cheers Pete.
