I wish to use the attached code to run my robot as an Obstacle Avoider. a run check on the code stops at CODEavgDistance=0/CODE and I am unable to find the solution.
This is on an Raspberry Pi 3 B with latest Rasbian O/S.
CODEprint ("right")
stop()
count=0
while True:
i=0
avgDistance=0
for i in range(5):
GPIO.output(TRIG, False) #Set TRIG as LOW
time.sleep(0.1) #Delay
GPIO.output(TRIG, True) #Set TRIG as HIGH
time.sleep(0.00001) #Delay of 0.00001 seconds
GPIO.output(TRIG, False) #Set TRIG as LOW
while GPIO.input(ECHO)==0: #Check whether the ECHO is LOW
pulse_start = time.time()
while GPIO.input(ECHO)==1: #Check whether the ECHO is HIGH
pulse_end = time.time()
pulse_duration = pulse_end - pulse_start #time to get back the pulse to sensor
distance = pulse_duration * 17150 #Multiply pulse duration by 17150 (34300/2) to get distance
distance = round(distance,2) #Round to two decimal points
avgDistance=avgDistance+distance
avgDistance=avgDistance/5
print ("avgDistance")
flag=0
if avgDistance < 15: #Check whether the distance is within 15 cm range
count=count+1
stop()
time.sleep(1)
back()
time.sleep(1.5)
if (count%3 ==1) & (flag==0):
right()
flag=1
else:
left()
flag=0
time.sleep(1.5)
stop()
time.sleep(1)
forward()
flag=0/CODE
