Cheap PIC Programmer
For this programmer you won’t need many materials.In fact , you will find all you need in your local electronics shop 😉
So here’s what materials you will need:
-RS232(Serial) FEMALE connector
-BC547B or 2N3904 (I couldn’t find the BC so i used 2N3904,it works great)
-5.1 V diode
-100 uF 16V Electrolytic Capacitor
-18 PIN IC Socket
-Flashing red LED / 2.1 V Standard Red LED
-Scissors or any other cuting tool
-Hot glue gun]
Step two : The scheme
As you can see , i tagged two connection in the scheme as “Optional point” one and two .
Those are the points where you will connect the “Optional” circuit i will show you in step 3
One pin of the resistor goes in the Optional point one , the other pin goes in the anode(+) of the LED.
The cathone(-) pin of the LED will go in Optional point two.
If you don’t understand , use the ellipse marked area of the scheme below.
