Hi .. i am not using processing for plot. It is just Arduino serial plotter.

yes, but accuracy is not sufficient,curretly i am working on accurate method with make use of 3 or more of these sensor.that may be helpful to you.

As correctly explained by notoriouscarl, both measurement are saperated by few milliseconds of time duration.

can you please explain why opto coupler required to read the signal?

Thanks for your thoughts, while starting this project I wanted to make it very close to human but during the course of time I realised that difficulties. If someone want to make it as good as a human artist, he must be an expert musician, expert coder and expert tinkerer.

more detail and video please.

thanks mam

I think the code for Tx is straightforward, but you are facing difficulty in the receiver . Am I right?

Use motor driver like l293d and change the code in the channel you are connecting to the driver with analogwrite instead of servo.writeThis transmitted would be good enough for low duty applications.

I have tested with flysky tx and working good. but you need to bind every time you start.

opps...corrected.thanks for pointing out

as first plane didnt flied well i switch my design to wing of which i do not have enough photo or video. so overall tutorial is bit discountinuus.

thanks sir for the words,i will keep it in mind while making next paper plane.

thanks, i took time but building that plane was a fun.

this code is way more slower for real time application. i highly recommend you to use fft.follow this article:http://wiki.openmusiclabs.com/wiki/ArduinoFFT

hello, the code uploaded would work with servo motors and ESC.

you can use any Arduino if weight is not an issue.

hi... Can please confirm that signal from ppm pin goes to any interrupt enable pin .. if that is ok. go to read_me function and check the output for variable "c". as mentioned in the code it is spacing between two peaks and should be similar spacing and channel value as data you capture using pulseIn function. if data in c is right than there may be some problem in code.

a,b and c is used to measure the spacing between two peaks in term of time. when a new data comes we store it in "b" (last data already there as old data named: "a")than take difference of "a" and "b" which is spacing in between two peaks.now as we have used latest data it is not new data (which we store as "b"), so we update old data. and make value of "a" equal to "b". now we again take new reading store it as "b"......so this process keep happens hundred of times per second.

It is serial plotter from Arduino IDE. Just update your Arduino IDE it is not available in older version.

thanks for vote

thanks lot

even after taking many precautions weight of my plane was 250g, and it took around 50-70 g thrust to fly. So if T/W ratio is >0.2 then it should work.

Thanks Lot.

hi...My receiver (of 6 channels) sends PPM for 8 channel (out of 2 are meaningless). I have chosen 15 just to make coding easy. so that, in any case, there is one set of 8 values which represents a value of each channel.for an example(here each number represents a channel number)2 3 4 5 6 7 8 1 2 3 4 5 6 7 87 8 1 2 3 4 5 6 7 8 1 2 3 4 5 5 6 7 8 1 2 3 4 5 6 7 8 1 2 38 1 2 3 4 5 6 7 8 1 2 3 4 5 6 here we can just pick 8 value after channel 1 if you use only 8 values it will become6 7 8 1 2 3 4 51 2 3 4 5 6 7 88 1 2 3 4 5 6 7so, in this case, we need to make rearrangement which is also not very difficult but I preferred easier approach.hope now you are clear about it. If you have any query let me know.

sorry, I don't have an exact idea. I have checked that values only on my Rx (avionics RZ6) and also on few websites.

yes . This code is inspired from that circuit only called "Lock-In amplifier". this is very useful system to extract data (of known frequency) from extremely noisy signal.

yes . This code is inspired from that circuit only.called "Lock In amplifier".this is extreamly useful system

I want to use these laser for low power (5-50 mW), can you please guide me how to achieve it?thanks in advance

Yes, It should work.if it not works, just check signal and do modification in code as per separation (step 1).If you don't have any problem with a delay in the reading channel (around 15milliseconds/channel) or do not wont to purchase PPM encoder you can directly use the pulseIn function for each channel.

Thanks lot... Hope this tutorial was helpful to you

These coreless motor can not take 9v. So you might burn it. Its recommend to use below 5v (any type of ) battery having max 15-20grams of weight.

Thanks lot...

thankslot

video please...that would fun to watch

extremely helpful. thanks alot

these cells are extreamly good for RC transmitter

first you need to specify an array and than store your data from adc to array. and dft of an array can be taken as explained.
