Hi,
long time ago when i started learning electronics and while i was playing with microcontroller programming, i found out this strange behavior, i do not remember what exactly i was trying to do :D, anyway, i waill be glad if someone explains what is going on.
as you can see when i get my hand close to PORTB.3, the led switches on "see the code below".
Notes:
*this works only if you are using DC power supply.
*this will not work if your home suffers from power outage!!!
The code "ProtonBaisc":
Device = 16F628A
Config INTRC_OSC_NOCLKOUT, WDT_OFF, PWRTE_ON, BODEN_OFF, LVP_OFF, CP_OFF, MCLRE_ON, DATA_CP_OFF
Xtal = 4
Dim led As PORTB.4
Dim var1 As Word
Main:
PulsIn PORTB.3,1,var1
If var1 = 0 Then
Low led
GoTo Main
EndIf
High led
GoTo Main
End
