ANTI MISSILE ROBOT_part 2

The very first time i think at what a robot does.that use a water rocket to be an ANTI MISSILE ROBOT......

the water rocket that carry an arduino-mini, when after auto tracking to the target and

auto de-attaching from rockets in order to avoid himself be destroyed !

and ~

the water rockets will not fighting each other because of the rockets
don't burn any fuel and they don't emitting light !

maybe there is someone wondering about the man who launching the rocket(part_4 : the tower) too !

soldering the control circuit for controlling the loose coupling motor.

i use a 2003 to integrate the H bridge circuit as an inverting circuit

, OR circuit in order to do --

1)STOP : power OFF.

2)FORWARD : power ON, forward ON,relay 1 OFF(reverse OFF).

3)REVERSE : power ON, reverse ON, relay 1 ON(reverse ON).

and then test the loose coupling motor gear again.

Since i don't have any wind hole, so i use water for testing with fan.

it's the same program with the launcher's program.
