Introduction: PIC Stroboscope
We are going to build this today. I am using the PIC12f675 from Microchip. THer is a video below to show the inner workings.
Step 1: Get the Parts
You will need:
6 volt battery pack (AA) (If you want, it can have a power switch and cover.)
7805 regulator (I use it in case I use a power supply.)
2 0.1 ceramic disc capacitors (it should say 104 on it.)
2n2222 NPN bi-polar junction transistor (use this transistor or a power transistor...I say this because 2n2222 can drive up to 1 amp but really, a transistor with 500mA will work.)
7 680ohm Resistors (I say seven because it has 1 "power led" See Notes at the bottom to hear why. This other LED also strobes like the others.)
potentiometer (I like 100K...gives me good range)
7 LEDs ( I prefer blue but any bright LED will work.)
PIC Programmer (I used the old fashioned QuickWriter.)
...and most importantly the PIC12f675 Microprocessor!
IC socket (this can double the height of your chip which may affect your LEDs positively or negatively.)
Three pin terminal block (female headers work too.)
Step 2: Build the Circuit
Build and plant your parts according to the schematic.
Step 3: Program the Chip
Download the software, set up the cables and program the code with the object code or if you want to be able to edit it , use the source code.
Step 4: Enjoy
We have a be nice policy.
Please be positive and constructive.
