i need help programming this...

[nxtprograms]

The web site (see video description) has a program you can download for this project (and building instructions too).

OK, the timing trick used on the button here is a little tricky, so try something a little simpler, such as:

1. Pivot turn while button is held down, then

2. Drive straight while button is held down, then

3. Hammer when button is pressed

and repeat all of this in a loop. You will only be able to hammer after going straight.

Parts 1 and 2 can both use:

a) Wait for touch sensor press

b) Move block set to unlimited

c) Wait for touch sensor release

d) Stop (Move block set to Stop)

well i was tryin something even simpler my algorithm was

1. Move forward while button is held down

2. Stop when released (a given)

3. Hammer when button is pressed

I can get it to move but idk wht to put in the program to make it hammer while its not in motion

[nxtprograms]

After stopping, the hammer part could be:

1. Wait for button press

2. Motor A down for 0.25 sec

3. Motor A up for 0.25 sec

You have to guess which direction is "down" for the hammer motor, so if it doesn't work, try switching them in the program.
