i need just small programming in pic16f54 micro controlor
when i give voltage to pic16f54
it should wait 10 to 30 sec (adjustable)
then ON/OFF a relay 4 times (ON/OFF time should be adjustable)
after 4 time ON/OF it should be stay off
thats it
simple like a flasher circuit
can anybody help me???
actually i have a 4017 counter circuit that start generator in 3 tries, i want to show it to 7 segment
- - - Updated - - -
check this circuit i want to attach with it
i made this on vero board, my 555 pulse generator is working fine, as i place LED there, and its blinking properly, but the 4017 part doesnt work like it showing in simulator plz help

here is what i did, but the LED, ALWAYS keeps ON :(
and the led attached with the output...
hello guys i found a circuit below but that doesnt work exactly,
i want to make it, like, it should ON/OFF relay 4 times and then stop until i cut power
plz can any explain it and make it properly??? or any software simulation????
here is actual circuit but i want to reduce it to upper one...
guys i need some help about the following sequential circuit, i made it on bread borad and in Multisim but not working as it describe :(
plz can u guys helo me???
**broken link removed**
here is Multisim file that im trying to simulate
**broken link removed**
like this or should i have to add diode in each??? (if yes then in which direction?)
- - - Updated - - -
or like this????????
if any correction please let me know
i think it will work fine, but please can u explain how i can attach relay, actually im not much expert i can just put up things as described in circuit, so i'd b happy if u can tell me how to add relay there
please can u post the circuit?????
actually i want to activate 2nd circuit when electricity (220v) goes off then then 2nd circuit (ON/OFF) should b activate, it will try to start self start generator (in 4 tries) i hope you got what i want to design now
Analog would b fine so i will b able to get parts easily, please send me circuit design actually i want to use it in power generator auto start

I know 555 ic will use but plz post the circuit
guys i need a 2 circuit the one is
when power applied the timer will trigger and the relay will remain off
when the timer runs out the relay will turn on and close the 2nd ciruit
and the 2nd circuit should b ON/OFF relay drive 4 times only and the ON/OFF
delay should be adjustable, after 4...
