wireless servomotor control

[D.V.G. Krishna]

hi every one

im working on servo controller

i made it using 555 timer ic in astable mode

and i generated the PWM wave

it worked

 

now i want to control it wireless

can any one tell me how to transmit PWM generated from 555 ic to servomotor

 

is it possible with RF MODULES

[D.V.G. Krishna]

i’m using 555 ic to generate appropriate pwm wave form

 it is working good

here im not using any mc

i want to know is can i connect  3rd pin of 555 to

tx and rx to the servo

Use a RF transreceiver. connect your 3rd pin to data pin of ttransmitter and connect the receiver output to servomotor data pin via an amplifier circiut. that should do it.

I am new to this stuff recently I came across this. I want the detailed diagram and procedure of the same topic can  you please post it?

u can do it using IR LED and IR sensor TSOP1738. i have posted one such project

but if u want to do it with RF only then u need encoder-decoder and micro controller

u can not simply build it using IC555

Thanks for reply can you please share the link of that project? As I want to apply this in daily life automation I want economical solution so I think your idea may fit in my situation. Do I need to amplify the signal at reciever end? because in RF reciever it will give the output of about 0.7VCC which is enough for data pin of servo what about in case of IR?

all u have to do was to just search. here is the link
