controlling several leds with 1 picaxe
Hi.
I am looking to find the best solution to control 5 rgb leds with 1 picaxe.
I know that ways to do this have been discussed many times, I am not asking for ways to do this! I am asking the experts here for their advice on the BEST way to do this.
I am working on a prototype for a product I am planning on selling, so this method needs to be the least expensive, but still be able to do what I need it to do.
I simply need to be able to control 5 rgb leds. They do not need to be able to "fade" (by fade I mean change brightness... for example the color orange fading in and out).
But they do need to be able to flash on and off and obviously pwm for different colors.
I am thinking as of right now that my best option is the tlc5940 however if anyone knows of a less expensive alternative, please let me know.
I have been quoted ~3.88 usd per piece for 1000 pieces for this chip.
I have also come across the tlc5926 chip which seems to be less expensive (1.74 usd/piece for 1000 of them). A glance at the datasheet makes me think that this chip would work fine, however I am very very new at electronics and don't trust my judgement just yet. It also makes me nervous that searches for other people using this chip for projects have come up as almost nothing.
Why is everyone using the tlc5940 rather than the less expensive tlc5926?
I'm hoping that people with experience with this topic will be able to help me make the best decision for my project.
thanks
