i think you are right.if we control the DC motor by portC and use portB to check the status of input sensor then theDC motor will work properly so that we could not use portB to control DC motor. i try this i get successful
Thanks for all
sorry i do not understand you what differene if i use the PB07 with PWM software or hadware
what i do i make programe to make PB07 run motor few second then turn off but the motor did not run propely .however if i use led insted of motor the led turn off and on propberly
i want to control DC motor using PIC18f452& transistor TIP120 and i use port B (PB07) to switch on and off but the problem the motor does not run properly
i heard that we have to use port C to control motor because portB is weak pull up
is it true??
Re: simple DC motor control - help needed
Thanks for all
i think i find the reasons .. the voltage of the base of transistor should be less than
voltage of that connect to DC moto to transistor i make the voltage of base= 1.5V with series with resistance 100 then the DC motor will...
Re: simple DC motor control
exactly i do not know but if you connect the motor direct with 5V it will work even i try to use 10V in the circuit but the motor does not work
hi
i try to make the simple DC motor control by trsnasistir but the motor will not work but if i put the LED in place of the DC motor the circuit will work and the LED will flash
in the attachment is the circuit can you tell me what is the mistake in the circuit
Re: Delay in PIC
the capacitor =22pf, crystal=10 mhz
PIC18f452
i make the dealy will work in the program if the input port pin#36= on
i use MikroC
what i see
if the voltage of PIC and (input port pin #36 on )between 5-7V the delay loop
will delay correctly
if more 7V the PIC will not...
pic delay
hi
i use delay(1000) of MikroC in the programming pic18f452 but the problem the PIC wlll not delay correct and i see sometimes if the voltage of PIC between 5v and 6v thePIC will give you correct delay if more or less than this the PIC will give wrong delay.... is this...
loop in the PIC
hi
i want to make loop (delay) for 10 second in the pic but i do not succeed
it will delay only for less than one second can you tell me what is the problem or missing in part of the code below and what is require to make delay 10
count equ 0xFF
loop
bsf PORTB,7...
how can we control the DC motor with PIC16f84 .in the attachment i try to connect the DC motor to make it off or on but i do not succeedd why pleas help me
why the circuit is not correct
