ARDUINO POOL ALARM...

-

just new dad's, @ worrying. topic has been heavy me in ground pool.

been looking around few days swimming pool alarms.

i looking build diy pool alarm. problem dont know detection method best. options are: ir, pir, , laser. have strong background in lasers , can build electronics rough on programming side. ( im working on that)

the pool 15'x32' , under 25000 gallons. getting power electronics not issue. trying figure out how detect child falling pool. ideas, suggestion, directions or critique welcomed....

if new dad young child. unfortunately answer (and comes shock) constant vigilance. on guard 24x7x356.

physical barriers next line of defense, won't work.
for electronic detection @ commercial systems see how tackle problems, won't work either.

i have been in pool on couple of occasions when healthy teenagers have slipped silently trouble, no fuss, no noise, no splashing. fortunately both times spotted things wrong i.e. floating face down unconscious on 1 occasion , sinking bottom on other.

sorry.

hello, im confused uno r3, uploaded code quite few months in uno, working fine. now without having altered of circuits, trying upload code changes,im getting strange error "avrdude: verification error, first mismatch @ byte 0x0000          0x0c != 0x62" i tried research able solve issue,  im running kind of fuse bit being changed or clock speed altered, im pretty sure did not play around these items. any people, please . . thanks taz Arduino Forum > Using Arduino > Installation & Troubleshooting > avrdude: verification error, first mismatch at byte 0x0000 0x0c != 0x62 arduino
