has 4 buttons, and since every key has its own wire line, no matrix code is
required - just treat these like every day switches.Specifications·
with 8 bit Microcontrollers·
communication selector switch is used for two UART communications to interface the
microcontroller at the same time.In
microcontrollers we can use only one UART but in some projects we have to
connect two UART communications at the same microcontroller, the problem arises
at that time..
Capacitive Touch Module uses the touch-sensing IC TTP224 to sense the touch
input. The module has 4 touchpads. Power the module with 2.4 ~ 5.5V DC and the
touchpad is all active to sense the input.Four-Channel
Capacitive Touch Module is easy to interface. It can be used along with a
12-button keypad provides a useful human interface component for
microcontroller projects. Convenient adhesive backing provides a simple way to
mount the keypad in a variety of applications. The Keypad 4x3 features a
total of 12 buttons in Matrix form. A female 7-pin berg connector is ..
is a small buzzer module that operates around the audible 2 kHz frequency
range. It is an active buzzer, which means that it produces sound by itself,
without needing an external frequency generator.It
can easily be used with microcontroller boards, like Arduino, without needing a
Arduino P10 Led Display Shield is a plug-and-play type that allows you to add a
Scrolling LED Display to your project. Shield for the Arduino P10 LED Dot
Matrix Display Using this shield with your Arduino Uno R3 is a breeze. Simply
connect it to the Shield with an Arduino Uno and a Panel Da..
Arduino Uno is the most popular Arduino board to date, but it can be
frustrating when your project requires a large number of sensors or LEDs and
your jumper wires are a mess. Base Shield is a simple way to connect to Arduino
boards and eliminates the need for breadboard and jumper wires. Yo..
The Digital Sensor TTP223B Module Capacitive Touch Switch is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; when a finger touches the corresponding position, the module output high, if not touched for 12 second..
This custom designed module for the DS1307 Real Time Clock. The module comes fully assembled and pre-programmed with the current time. The included Lithium coin cell battery (CR2032/ 240mAh) will run the module for a minimum of 5 years .without external 5V power. The DS1307 RTC is accessed via the I..
Module is a breadboard-compatible, extremely precise I2C real-time clock
Module. This module incorporates a DS3231 RTC and an AT24C32 EEPROM, as well as
a temperature-compensated crystal oscillator. It also includes a comparator
that monitors the status of VCC in order to detect power..
decodes DTMF signal either from an audio source or phone line to 4 bit binary
TTL (5V) level output. It also indicates outputs with LED. Can use directly
with microcontrollers to develop various DTMF relate applications like remote
monitoring, remote control, Caller ID, Auto Dialler.S..
The PCF8574 is a silicon CMOS circuit. It provides general purpose remote I/O expansion for most micro controller families via the two-line bidirectional bus (I2C-bus). The device consists of an 8- bit quasi-bidirectional port and an I2C-bus interface. The PCF8574 has a low current consumption and i..
