The ESP8266 is an impressive, low cost WiFi module suitable for adding WiFi functionality to an existing microcontroller project via a UART serial connection. The module can even be reprogrammed to act as a standalone WiFi connected device – just add power! 802.11 b/g/n protocol Wi-Fi Direct (P2P), soft-AP Integrated TCP/IP protocol stack This module is a self-contained SOC (System On a Chip) that doesn’t necessarily need a microcontroller to manipulate inputs and outputs as you would normally do with an Arduino , for example, because the ESP-01 acts as a small computer. Thus, you can give a microcontroller internet access like the Wi-Fi shield does to the Arduino, or you can simply program the ESP8266 to not only have access to a Wi-Fi network, but to act as a microcontroller as well, which makes the ESP8266 very versatile.
Like the mini pressure sensor, but bigger! Our 3x3 mega pressure matrix has 6 leads, allowing you to map which point you are at in the 3x3 matrix and get a pressure mapping over a surface. Each area has an analog readout that varies depending on the weight of the item on the pressure sensor. Generally, sensor values will read from 500 Kohms to 100 ohms depending on the force put onto the sensor.

NFC is a popular technology in recent years. Almost all the high-end phones in the market support NFC. Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. This module is built around NXP PN532. NXP PN532 is very popular in the NFC area. Makerfabs developed this module based on the official document. A library for this module is available.
