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 ...

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 ...

A simple four-component circuit allows a single I/O line from any microcontroller to sense the states of two capacitive touch sensors. With so many cell phones, PDAs, and MP3 players using ...

In the last Sensor Sense we looked at capacitive touch switches used for on/off control. But these switches are also found in capacitive touch sliders that can control various levels, such as volume ...

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 ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

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.

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 ...
