A 4x4 matrix keypad requiring eight Input/Output ports for interfacing isused as an example. Rows are connected to Peripheral Input/Output (PIO) pins configured as output. Columns are connected to PIO pins configured as input with interrupts. In this configuration, four pull-up resistors must be added in order to apply a high level on the corresponding input pins.

Note: The color of the PCB may vary. However the circuit/pinout of the PCB will remain same.

One of the basic interfacing requirements for the hobbyists or electronics enthusiasts is I/P (keypad) and O/P (LCD display)  for proyotype applications. This shield uses minimum number I/O’s that is 4 bits for LCD data and 2 control signal lines for the same. A single analog pin (Pin A0) is multiplexed to read 5 input key switches (Navigation keys). Each key has been pulled up to a different voltage level, so a different voltage will be generated every time a user selects a key. This voltage could be read by the analog pin A0 on the board. Hence saves the no of I/O pins.  The backlight of the LCD could be controlled by setting PWM (Pin D10) by adding a few lines of code.

The Moisture level of the soil can be detected by this sensor. When the water level is low in the soil, the analog Voltage will be low and this analog voltage keeps increasing as the conductivity between the electrodes in the soil changes. This sensor can be used for watering a flower plantor any other plants requires automation.

The board can be used in applications where dimming of 110-220V AC power is required like dimming of bulb or fan. The board can be control with a serial data from any microcontroller 0-100% dimming or ON/OFF control.Board also providing an option for connecting bluetooth and controlling tha loads from any smart apps. Mains power (230v) completely isolated from the microcontroller.

Bidirectional Logic Level Converter is a Four-Channel Device which can be used for Voltage Level Shifting between two devices.The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the 'H' pin, low voltage (3.3V for example) to 'L', and ground from the system to the 'GND' pin.
