i had just purchase BC517...the scenario still the same...
actually for the relay i'm using Sangle 6v relay
**broken link removed**
can anyone suggest any suitable relay?
or can i use Car Relay?
Thanks for suggestion...i had made what u all suggest except still using BC107 since i don't have any darlighton type in my collection....
the result when i connect the NC...the motor works, but it doesn't respond to the PIC input....
When i connect it with NO ...the motor OFF....
I wonder...
yup i bought it from cytron
i had done the programing....in C
can u check it for conformation..
#include <16F877A.H>
#device ADC=10
#fuses HS, NOWDT, NOPROTECT, BROWNOUT, PUT, NOLVP
#use delay(clock = 20000000)

here is schematic that i found regarding automatic light controller based on human detection...
so here i wanna ask...isn't ok to use this diagram...by replacing AT89s52 with PIC16f877A and the InfraRed sensor being replaced...
PIR sensor pIC16f877
hi everyone , i want to ask on how to deal with PIR sensor...PIR sensor is basically a motion detector that detect motion...so in this case, i would like use that sensor to act as as input to my ceiling fan controller( using LM35 sensor)...
the problem is, this sensor only...
Re: want to ask....
the LED just blinking . For example if temperature - more than 30 degree... the LED at pin D5 just blink...not totally on....isn't the code wrong?

hi everyone, i want to ask...what is the suitable sensor to detect human....
the scenario, the sensor will detect the human as the he/she enter the room...the sensor somehow will act as switch off / on...this sensor will be combine in my temperature sensor- fan circuit...so, as the human being...
just to ask opinion - if the code is ok
here is the simple code...that i made out based on the mikro C code given above..
isn't correct?...the compalation is good..but the truth is the circuit still not been build yet..since i will buy the transistor this evening...so hopefully someone can...
just to ask opinion - if the code is ok
hi again...
how about the circuit connection...isn't just directly implement the Pwm pin towards DC motor ...no need any others element?...huhu...sorry for my weakness
Added after 5 minutes:
isn't ok for me to follow-up with this kind of...
just to ask opinion - if the code is ok
finally i had managed to get the result..
2 cases already been done
* display simple word at LCD
* display temperature capture by LM35 sensor
the problem is basically on the lcd 16x1...totally can't be used...when i replace it with LCD 16x2 ...it yield...
just to ask opinion
hello again...i have try the code in the link...still the result quite the same...i wonder why?
any help?
Added after 58 seconds:
i though using LCD 16x1 is quite hard...i'm planning to replace lcd 16x1 with lcd16x2...
just to ask opinion
so,based from this link, you stated that the problem lies on source code?...still need adjustment?....
right know, i'm going to do a test...perhaps...tonight i will respond to ur about the result...hopefully u willing to help...
