The circuit was specially designed for shop windows animation as it makes use of a capacitive sensor that is triggered by touch control system. BC337 – a small signal NPN Silicon AF medium power ...

With so many cell phones, PDAs, and MP3 players using touch-sensitive keypads, wheels, and screens for user input, regular mechanical pushbuttons are beginning to seem outdated. Even so, mechanical ...

Capacitive touch sensors are based on the electrical capacitance of the human body. When, for example, a finger comes close to the sensor, it creates a capacitance to Earth with a value of 30 to 100 ...

This PLL-based circuit implements a touch-switch circuit using the PC board or small metal pads as sensors; it is radiometric and thus insensitive to changes in temperature and supply voltage.

ON Semiconductor has introduced a highly integrated capacitance-to-digital converter IC that will speed the implementation and reduce the component count of electrostatic capacitance touch sensor ...

According to several recent Embedded Market Surveys, 65 to 70 percent of the developers who responded said they use more than one microprocessor or microcontroller in a single design, but only 4 to 7 ...

Ever wondered how a touch-sensitive screen works? The answer is capacitive sensing, which can detect the presence of your finger through the protective glass sheet and doesn't require any pressure.

Apple is examining a shift from a force sensor in AirPods to a capacitive touch system to make a set easier to control, and provide new options. The latest in Apple's surprisingly long history of ...

Year on year, microcontrollers and development platforms are shipping with ever-increasing feature sets. In the distant past, if you wanted an analog to digital converter or a PWM driver, you had to ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...
