LCD Interfacing to PIC16F877A ,I want to display 5 names flashing, running,steady
first display 1'
2nd display '2'
3rd display '3
4 display '4'
5 display '5'
and if can be possible to control via printer port:flashing, running,steady
using install software

Do not forget to put a Heat =sink aluminum..make your own pcb i you like to make it

If you like to make much better pcb layout , just post here thanks
F=1/T= 1.44/((RA+RB*2)*C)
TL= 0.693*RB*C
TH= 0.693*(RA+RB)*C
D= Duty Cycle= (RA+RB)/(RA+2*RB)
Or,
RA= 1.44**(2*D-1)/(F*C)
RB= 1.44*(1-D)/(F*C)
Added after 1 minutes:
The minimum duty cycle is 50 percent, so if you need a smaller duty cycle you need to use an inverter on the output.
15 AMPERE
POWER TRANSISTORS
COMPLEMENTARY
SILICON
60 VOLTS
115 WATTS
Added after 2 minutes:
There are two limitations on the power handling ability of a
transistor: average junction temperature and second breakdown.
You can supply up to 24 volts with no exploxions of IC because it regulated by Transistor, it just add another output powers

100 persent i simulate this and tested..
