The DS1302 trickle-charge timekeeping chip contains a real-time clock/calendar and 31 bytes of static RAM. It communicates with a microprocessor via a simple serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator. Backup battery: CR2032 Included.

This package includes a water level sensor and a soil moisture sensor. If the boards have water covering the sensor parts, an analogue value will be available at the "SIG" connection.

A capacitive sensor is a touch sensor that requires little or no force to activate. Detects body capacitive touch, outputting analogue voltage.

RGB LED module with on-board current limiting resistors.

A Reed contact switch is a normally open contact which closes in the presence of a magnetic field. This modules contains a 10 Kohm pull-up resistor.

This module contains a push button and a 10 K pull-up resistor.

This module contains a vibration switch and a 10 K pull-up resistor.

This Joystick module provides X and Y axis control for your microcontroller projects. It also includes a "push down" microswitch. 2 Pieces

This module can be used to send data by using infrared light. Commonly used in remote controls.
