Hi thanks for the updated code it worked nicely on uno. But Sourav the movements while recording are not precise enough.. like while recording its very hard to get the gripper right on top of the object which needs to be picked up. However, while playing it moves fluently. I understand that may be you should not expect too much with these micro servos but still, can you do something to make the recording movement more precise or fluent.I was trying to upload my videos here but failed, may be only pictures are allowed here

Hi SouravTo increase its memory i have connected it with arduino mega but then servos were behaving weirdly and two of them were not working at all.Please guide me how to connect it with mega and how to change the code for mega. with thanks

you know when i added the 4th servo the dynamic memory got jumped and exceeded the limit but then after many attempts I finally got the recording time of 50 sec by changing following:N=4recttime=50samplepersec=4dynamic memory 91% used by global variables.with 50secs in hand then i was able to record a decent pick and drop task in a loop which worked fabulously.

mega is like a beast when it comes to dynamic memory comparison with uno. I am extremely desperate to enhance the learning memory upto 3 times of the current one which is now 50sec. The goal is to develop a sorting bot application so that at least after getting enough learning memory it will be able to perform three different lift and drops for 3 different sized items and 3 different dropping positions. I had conducted individual servo test with mega but no success. Or any innovative application if u can suggest, would be highly appreciated.On mega everything seemed fitting and same like uno except that mega has separate digital pins and pwn pins which might have causing the trouble and i used mega's pwm pins for my four servos, starting from 2 to 5.lastly, i couldn't find the pin definit…

I can't interpret complex formats of coding except the basics formats and theoretical concepts. Please do explain me about changing pins and then i will be able to try it to connect and control with mega.
