How to control a robot using mobile phone is what we are worried about . Now have you noticed that when someone calls you and he clicks on his keypad you’l recieve a tone.If you were more concious of that , did u note that each key pressed has a different tone These tones are called DTMF tones .
Now you’ve got a transmitter and a receiver. Now all you’ve got to do is decode the carious tones to detect the different keys pressed.This can be done by using a DTMF tone decoder.
HT9170 is the IC used to peroform DTMF tone decoding . This Ic gives out 4 bits based on the tones received. once we obtain the digitl data the following process is just a cakewalk. Use a Microcontroller based on those bit combinations received give appropriate signals to the motors. Now that’s sounds really cool and simple.
Now how do you run the motor?? what! you still don get it? just make a call to the robot and make it move
