please view this for info.




it was made for someone special....little bit of electronics and craft made it possible.....
(Components : ic555, l293de, relay , a motor)

theoutput of the 555 ic has been given to the motor driver ic(l293d). then the motor driver drives the relay for both positive and negative polarity. this results into its timing clockwise and anticlockwise direction.......


next is the simple blinking of lights in heart shape using 555 in astable mode......
remember to use switches where ever required...


thanx for watching....
have fun
:)
