I need a circuit that can blink 50 LEDs at a speed of 1Hz adjustable up to 10MHz or more.
Adjustable resolution of 1Hz steps.
LCD screen to display frequency.
Buttons or dials to adjust speed.
Perhaps 1 button for Hz, 1 button for MHz?
On/Off button or switch.
9 volt operation for prototype.
and if that works, I will need a 12 volt model with no LCD screen,
12v model should work only on a programed frequency. Not adjustable.
12v model should power 100 LEDs, in two sets of 50.
I build my own circuit board and prototype.
Please no milestone payment until prototype is working.
I have paid two Freelancers before that collect money and provide broken designs (no hardware) that never works so I will not pay anything until this one works, as per Freelancer.com recommendations.
PIC chip is ok and preferred. =)
Thru hole components preferred for prototype.
SMD components are ok for resistors, transistors, diodes, capacitors, but NOT for IC or PIC.
Thru hole only for IC and PIC.
