The ESPLORA Joystick Photosensitive Sensor Board is a microcontroller board compatible with Arduino & derived from the Arduino Leonardo. The ESPLORA Joystick Photosensitive Sensor Board differs from all preceding Arduino boards in that it provides a number of built-in; ready-to-use set of onboard sensors for interaction.

It’s designed for people who want to get up and running with Arduino without having to learn about the electronics first. For a step-by-step introduction to the Esplora; check out the Getting Started with Esplora guide.

The ESPLORA Joystick Photosensitive Sensor Board has onboard sound and light outputs, and several input sensors; including a joystick, a slider, a temperature sensor, an accelerometer, a microphone, and a light sensor. It also has the potential to expand its capabilities with two Tinker-kit input and output connectors, and a socket for a color TFT LCD screen.

Like the Leonardo board, the ESPLORA Joystick Photosensitive Sensor Board uses an Atmega32U4 AVR microcontroller with 16 MHz crystal oscillator. And a micro USB connection capable of acting as a USB client device like a mouse or a keyboard. In the upper left corner of the board, there is a reset push button, that you can use to restart the board.

There are four status LEDs

Arduino Pro Mini ATmega328The Arduino Pro Mini is intended for advanced users who require flexibility, low-cost, and small size. It comes with the minimum of components (no on-board USB or pin headers) to keep the cost down. Be sure to provide the correct power and use components whose operating voltage matches that of the board.
The board comes without built-in USB circuitry, so an off-board USB-to-TTL serial convertor must be used to upload sketches. This can be a FTDI TTL-232R USB - TTL Level Serial Converter Cable for the 5V Arduino Mini Pro), or a FTDI TTL-232R-3V3 USB - TTL Level Serial Converter Cable. One quick way to connect these is by inserting a six-pin 0.1" male pin header into the end of the FTDI cable or breakout board, and pressing it against the six hole programming header on the Mini Pro. If, however, you''re going to be uploading lots of sketches to your Pro Mini, you''ll probably want to solder some pins (male headers) to the holes.
The board can be powered through USB via the six-pin programming header, or from a regulated 5V (depending on the model) supply applied to the VCC pin or an unregulated supply on the RAW pin.
Any standard 0.1" spaced header can be soldered to the holes on the Arduino Pro Mini. To use every pin requires two 12-pin headers, plus a six pin header for programming, if desired. Bare wire can also be soldered directly to the holes.

ATMEGA 328 Specifications : 

• 131 Powerful Instructions – Most Single Clock Cycle Execution

Nextion  3.2″ HMI TFT Intelligent LCD Touch Display Module is a seamless Human Machine Interface (HMI) solution that provides a control and visualization interface between a human and a process, machine, application or appliance. Nextion is mainly applied to the Internet of thing (IoT) or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube.

Nextion includes a hardware part (a series of TFT boards) and a software part (the Nextion editor). The Nextion TFT board uses only one serial port to communicate. It lets users avoid the hassle of wiring. We noticed that most engineers spend much time in application development but get unsatisfactory results. As a solution to this situation, Nextion editor has mass components such as button, text, progress bar, slider, instrument panel etc. to enrich the interface design. Furthermore, the drag-and-drop function ensures that users spend less time in programming, which will reduce 99% of their development workloads. With the help of this WYSIWYG editor, designing a GUI is a piece of cake.

It’s easy to adapt Nextion family HMI to existing projects. Users just need to provide it a UART.
