Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, posi… ...

Capacitive sensor technology has evolved markedly over recent years, underpinned by advancements in integrated circuit design and novel measurement approaches. These sensors function by detecting ...

If the water is somewhat low, the Arduino-controlled relay powering the tree is switched off and then on again, every 5 seconds. If the base is nearly dry, the tree asks for water by blinking the ...

Bare Conductive raised over US$200,000 on Kickstarter last year for an Arduino-based project called Touch Board that ... A demo of Touch Board as a capacitive sensor. 5 / 15. Touch Board as an ...
