Very good really. Can you please provide PCB layout as well (Seems the images are from Proteus, so you could take the PCB layout quite easily?).
Also I would try this on a smaller micro like PIC 12 series or ATtiny series. How do you think Magneto... is it possible to do without a code change to RkskEkanayaka's code?

Hi shane,
my proteus version doesn't give pcb layout because of it is a patch of a lite version, therefore it hasn't librabries for all the componots. sorry.
if anyone can put pca layout, It will be a good work.
thankz.
