[arohi25]

with voltage regulator 7805, how much volt battery should be used -> 6v or 9v ?

[Avadhut.Deshmukh]

6v only without voltage regulator !

[arohi25]

wont it damage any component ???

[Avadhut.Deshmukh]

Without burn ! only 6v !

[arohi25]

[arohi25]

these are the photos of pcb, the black-red wires are for connection of battery of 6V, 4.5AH connected through 7805 voltage regulator(to prevent circuit components from any damage). 4 motors are used.

[supri]

are u use voltage regulator and why u use it......and where.....

[Avadhut.Deshmukh]

only 6v !

[robot1398]

where did you get the atmega in india

[Avadhut.Deshmukh]

Atmega16 it is widely available everywhere ! http://robokits.co.in/

[robot1398]

and the programmer

[Avadhut.Deshmukh]

6v only without voltage regulator

[vaidya]

how to connect ear phone with it???which wire we should give to the input dtmf decoder ... and which should be grounded????

[Avadhut.Deshmukh]

tip=tone and ring=GND

tip to green wire from jack and black to GND from Jack to connect ear phone done :)

[ajinkyadixit]

can i use 80v51 RD2 OR 8051 MICROCONTROLLER ?????
withe same code???

[Avadhut.Deshmukh]

Same no !

[mudz_07]

sir how did u connect the mt8870 DTMF to not gate and to atmega 16?..

[kevinmaru28]

can u please tell me what would be total cost of project (cost of components) in rupees

[Avadhut.Deshmukh]

Rs.500-1000/- low price ! ! :)

[aliyevzaur1989]

Dude....cut or clean your nails.....so disgusting...

[Avadhut.Deshmukh]

ok i work PCB black

nail sorry !!

[varunkmanikandan]

how to burn the atmega 16

[Avadhut.Deshmukh]

AVR ISP programmer burn !!!! Yes !

[kpkpkalpesh]

really nice project dude................

[skumar mahalatkar]

how to identify Ring & Tip in Ear Phones???? and can v use any mobilephone @ robot end!!!

[fmazi]

interesting stuff

[pkumar10]

did you use ceramic capacitor of "0.47micro farate" ??. I have used electrolytic but circuit is not working.
plz rply soon..............

[robot1398]

i dot think u would get a electrolyte capacitor of 0.47uf thats impossible
u can get a ceramic capacitor of 0.47uf

[acudappah]

the motor is running as soon as i put da battery..da driver is not listening to the mc..wat to do??

[tbone121]

great job, but you should post some pictures of the actual building process and maybe a video of it operating

[zazenergy]

Agreed. This looks really cool, but it would be great to get some more photos.

[Avadhut.Deshmukh]

Video Yes !

[nyadav1]

nice stuff

[Avadhut.Deshmukh]

Thanx

[hdhiman]

nice instructable thanks

[vaggarwal]

Nice project :)

How to connect the Not gate between Dtmf decoder(mt8870) and atmega16??[N1 to N4] I have used the 74LS04 NOT gate. cant figure out which connections are to be made. You havent specified how you used the same in the circuit diiagram

Also how did you make the four wheel drive?? using gears or adding two more motors in parallel??

Plz reply soon
(or mail me at [e-mail])

[matt21century]

kya ye 1100 hai????????

[simplebotics]

cool robot, second follower too, nice job too!
