Hi,
After a few small projects I'm trying to plan out a big one
And yes, it's another led table... It's been a dream though for a couple of years to have an interactive table (ever since the microsoft surface table was introduced).
So the idea is to create a tabletop of 12 x 18+ cathode RGB leds (216+). Each of these leds would be put in a halfenclosed box of 5x5cm
Now whats the cheapest solution to identify a touch? After some reading I came across IR proximity sensor, but it costs around 10€ a piece. (100+ is about 8€/piece), which seems a bit expensive If I need around 216 (1 for each box + some reserves).
Fyi I'll be using a semi diffused plexi plate to cover up the table.
So is there maybe another solution?
