What I really would like to see is some more competition and price drops in displays. These microcontrollers are awesome and I love building small hardware projects. But the output systems are usually pricey. If color (ideally touch) displays can be made available for $5-$7. That would open up a flood gate of opportunities.
- penagwin 7y agoOne of the most common outputs is relays, thankfully those are pretty cheap. Displays are getting close your price which is great. Depending on what you're doing you may want to consider purchasing something like a kindle fire for 50$ though and rooting it. Or even a pre-paid "smartphone" for under that much. Then use a microcontroller with it for GPIO.

- leggomylibro 7y agoColor displays are available for $5-7, although they are usually only 2-4" diagonally with up to 240x320 pixels at 16-18 bits of color per pixel. But it definitely did open up a flood gate of opportunity. You see ILI9341 and ST7735 TFT displays all over the place, even if they're a little too small for large pieces of equipment. Not to mention the explosion in cheap individually-addressable color LEDs and drone-driven advances in small DC motors. It's fantastic, you can pretty much just plug electronics together like Lego bricks at this point.
