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

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..
CH340 USB to Serial TTL converter chip is the foundation for this USB-TTL
converter. The module has the ability to transition from 5V to 3.3V logic level
via a 2-pin shunt that is included with the module, and it may be used for 3.3V
logic level signals. It has a little switch built in that ..
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..
