BotKropny, the ugly light-seeking robot

i have a sample code for SRF05 , i was just wondering if i have to use the same PULSOUT and PULSIN commands

here is my code :please comment !!

Symbol dangerlevel = 50 ' how far away should thing be, before we react?
symbol turn = 300 ' this sets how much should be turned
symbol servo_turn = 700 ' This sets for how long time we should wait for the servo to turn (depending on it´s speed) before we measure distance
symbol trig = 3 ‘ Define output pin for Trigger pulse
symbol echo = 6 ‘ Define input pin for Echo pulse
symbol range = w1 ‘ 16 bit word variable for range

main: ' the main loop
pulsout trig,2 ‘ produce 20uS trigger pulse (must be minimum of 10uS)
pulsin echo,1,range ‘ measures the range in 10uS steps
pause 100
let range = range * 10 / 58 ‘ multiply by 10 then divide by 58
readadc range, b1
if b1 < dangerlevel then
gosub nodanger ' if nothing ahead, drive forward
else
gosub whichway ' if obstacle ahead then decide which way is better
end if
goto main ' this ends the loop, the rest are only sub-routines


nodanger:' this should be your combination to make the robot drive forward, these you most likely need to adjust to fit the way you have wired your robots motors
high 5 : high 6 : low 4 : low 7
goto main

whichway:
gosub totalhalt ' first stop!

'Look one way:
gosub lturn ' look to one side
pause servo_turn ' wait for the servo to be finished turning
gosub totalhalt
readadc range, b1
'Look the other way:
gosub rturn ' look to another side
pause servo_turn ' wait for the servo to be finished turning
gosub totalhalt
readadc range, b2

' Decide which is the better way:
if b1<b2 then
gosub body_lturn
else
gosub body_rturn
end if
return

body_lturn:
high 6 : low 5 : low 7 : high 4 ' this should be your combination that turns the robot one way
pause turn : gosub totalhalt
return

body_rturn:
high 5 : low 6 : low 4 : high 7 ' this should be your combination that turns the robot the other way
pause turn : gosub totalhalt
return

rturn:
servo 0, 100 ' look to one side
return

lturn:
servo 0, 200 ' look to the other side
return

totalhalt:
low 4 : low 5 : low 6 : low 7 ' low on all 4 halts the robot!
Servo 0,150 ' face forward
wait 1 ' freeze all for one second
return

LOL. How many times have you (and others) had to say that lately? What's with the plethora of people showing up and posting "code please" lately? It's friggin  ridiculous.

To top it all off, this project has the code posted already, firdouse. Right there at the top, right under the first photo, "BotKropny.bas 2.42 KB".
