Re: LED backward breakdown voltage and LED as a indicator lamp
Another easy solution here,
Just get two LEDs and connect their opposite sides (like paralle).

Re: Single LED resistor calculator
Practically I've used 100k, 1/2W resistor with a LED. Current flow is too small, but it's suitable when you use LED for indication.

Re: Brand new PICKIT2 to our little genius Rksk
Yes, I received it within one working day. It is brilliant, I've never seen a 'Made in SriLanka' product like this.
They delivered to it my doorstep without any damages to package (even to cover).
Thank you sooo much ROBOT.LK.

Re: Make LED matrix array using a single microcontroller
Think about it as this. You TV refreshes the display 25 times per second. With two fields, it is like 50 fields per second. With a microcontroller, How fast you think you can refresh these LED displays ? That's how this scanning method work. Though it can be logically thought as drawing to one disp...

Re: Make LED matrix array using a single microcontroller
Can I use this for a large matrix display (like 16*64) ?Shane wrote:Circuit diagram for a moving LED matrix display.
Will it show good outputs?
