Infineon's CAPSENSE technology, which features low-power operation and a voltage range from 1.71 to 5.5 V, also provides a solution for liquid tolerance to prevent false touches in wet/moist environments. CAPSENSE solutions can put capacitive touch-sensing functionality into designs using PSoC Creator’s CAPSENSE component. https://youtu.be/MhrNCdwdnJY

Museum exhibits are difficult to make, and they’re always breaking down; especially the interactive ones. This is a combination of budget, building a one-off, and the incredibly harsh abuse they take from children. My first exhibit is an interactive laser show that turns waveforms from music into laser patterns, and different types of music have very different patterns. I knew from talking to the museum staff that industrial buttons were a necessity, but it turns out that industrial buttons are made under the assumption that tiny creatures won’t be constantly mashing, twisting, and (ew ew ew) licking the buttons. After …read more http://pje.fyi/PN4sKV

Capacitive Sensing: 3rd attempt was successful! For the touch sensing, a 10k resistor was much more stable than the 1M resistor. I also managed to debug the fading of the LEDs. For some reason when the pin is LOW the leds turn on, and when the pin is HIGH the leds turn off! I had to recode my whole led on/fade off part.

Capacitive Sensing: second attempt, more LEDs! Wired up in parallel this time, but since I had no external power source, I couldn't use that many LEDs
