connection1 -> black wire of the battery -> one terminal(black) of the switch
connection2 -> another terminal(red) of the switch -> one terminal of the bulb.
connection3 -> another terminal of the bulb -> red wire of the battery.
It should look like a ring when connected.
make sure there are no noise injected into circuit. there is the possiblitlies of high frequency injection from powerside.check the ground and VCC signal at controller . u can reduce noise by adding pi filters and common mode chock at power supply. add capacitors 0.1uf (and/or 10uf )nearer to...
Watchdog timer wont reset registers.
there is no option in controller to start back from where it reset.you have to implement that somehow in software.
PIC use seperate time for watchdog.only the prescalar is shared between watchdog and timer.
Re: help plz
If usng a microcontroller , use an opamp amplifier to scale the measurable temperature range into maximum ADC resolution. If no IC7107 or any led display driver ic will be the good choice.

initialise PORTA's appropiate pin as "analog & input" in ADCON1 register and TRISA register.
select ADC Pin from which Analog value to read in ADCON0

set ADGO bit
wait untill ADGO bit is cleared by hardware ( means ADC data is ready )
ADC Value =...
unconnected pin should be grounded
You can connect to positive supply or ground or left the pin open.
take the advice from the datasheet.Unless the manufacturer says "should not left open ... connect a capacitor or res to ground if not used" , you dont need to worry about the unconnected pin...

howard and van neuman architecture differs by the way of treating code and data memory.In howard architecture the code memory area and data memory area are seperate. code memory area is where you store your instructions , and data memory area is where we...
