Fingerprint scanners have been easily available at a consumer level for a number of years now, so it is only logical that they would continue to grow and evolve as time moves on. That's what bring us to this Capacitive Fingerprint Scanner from ADH-Tech. The AD-013 fingerprint sensor module is a combination fingerprint scanner and MCU and provides a UART interface port for easy functionality. The AD-013 sets itself apart from other finger print scanners with the ability to read a fingerprint's...

If you need to add user input without using a button, then a capacitive touch interface might be the answer. The AT42QT1010 SparkFun Capacitive Touch Breakout offers a single, momentary capacitive touch button with easy-to-use digital I/O pins. The AT42QT1010 is a dedicated, single-button capacitive sense chip. The chip handles monitoring a conductive area for touch. As long as a touch (e.g., from a finger) is detected, the AT42QT1010 keeps the output line high. Otherwise, the line is kept...

Do you want to replace a slider or a button on your art project or science experiment with a more interesting interface? This Capacitive Touch Slider is a "Qwiic" and easy way to add capacitive touch to your next project. With the board's built in touch pads, you can immediately start playing with the touch capabilities as three unique touch inputs or as a slider. You can also enable a touch input to act as a power button, customize the sensitivity for your own touch pads, and play with the...

The SparkFun Touch Potentiometer, or Touch Pot for short, is an intelligent linear capacitive touch sensor that implements potentiometer functionality with 256 positions. It can operate as a peripheral to a computer or embedded microcontroller or in a stand-alone capacity. The Touch Potentiometer provides both a dual-channel analog and PWM output for direct control of other circuitry. Configurable analog and PWM transfer functions support a wide variety of applications such as volume control...

The SparkFun Variable Load Kit is a quick-to-assemble board designed to allow users to draw a specific amount of current from a voltage input. This kit can be used to test stability of the power supply under various loads, battery lifetime, safety cutoffs and other design elements. The Variable Load Kit can test supplies of up to 30V at currents ranging from a few mA all the way up to 4A. The Variable Load board is meant to work with one of two output modes: either using a console on a PC for...
