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?

There is the proteus schematic design file.

Hello, can you put png images of the layout please? (Just get screenshots of exact size).

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.
