Hi,
I'm brand new to the PICAXE but I've bought the 14M2 starter kit and programmed some basic flashing LEDs and read through the manuals.
I use LEDs for scale models and dolls houses and I want to start using the PICAXE board for programming effects with LEDs.
The project board is fine but it has a lot more on it than I really need.
I would like some advice on how easy it is to make a smaller board with the bare minimum on it.
Initially I'm looking at requiring:
an on/off switch as an input.
Several LEDs as outputs (how many can be powered off one board?)
I would like to remove the download socket because I would programme the chip and then it wouldn't need to be changed again and I don't think I need the darlington driver? I'm not 100% sure I understand what it does.
I'd also like to investigate if it's possible to power the board with a smaller power supply or lower voltage? The 3xAA battery pack is quite big for my usual projects.
Is the output of the board 4.5V? The manual says to use a 330ohm resistor which is high for 4.5v for a white LED. I'd normally use this with 6v and given LEDs are different vf I want to calculate the resistors more accurately as I use all the main colours.
I ideally need a board that is easily reproducible and quick to make.
If advice could be tailored to someone who's not an electronics natural I'd appreciate it. I try hard but some stuff I take a while to grasp
Any help appreciated.
Thanks, Jennifer,
