This page contains a list of project using the Arduino JSON library. It's a wiki, don't hesitate to edit this page if you want to add a project.
WIoT-2 Weather Station - www.plastibots.com
Uses NodeMCU + Nextion + Blynk + ArduinoJSON to parse and dispay weather and other information. Full write-up at PlastiBots.com.
- Display current and forecast weather information. This time around, I used the Weather Underground API to pull both current and forecast data in JSON format.
- Display weather data generated outside the house via another ESP unit. It polls temp, humidity and battery info (it’s solar powered) – Integrated with Blynk
- Poll and display the temperature of the hot tub – Integrated with Blynk
- Poll and display the status of garage doors (open/closed) – complete. will be integrated in the future – Also integrated with Blynk
- Allow our kids to interact with the unit – sends notifications via Blynk
- Polls waste collection calendar information to show us which waste items are being collected on a weekly basis.
- Show the current date and time – uses Blynk RTC widget
- I also added a picture viewer which shows family photos (for those times when people are bored standing at the door waiting for others…)
Aquamonitor & AquaNet
By Reivax
Device to monitor a reef tank and send SMS alerts in case the vitals turn bad.
An Arduino Mega scans 4 sensors and uses a GSM shield to send SMS alerts when thresholds are reached.
Linked to the Mega through Serial line, the ESP8266 exposes a webApp that displays the measures and can edit the settings, and sends the measures to an externally hosted DB to be able to build charts.
ArduinoJson is key for the communication between the Mega and the ESP, the ESP and the webApp, as well as for sending the structured data to the statistics host. It will even be more important in version 3, when several modules talk together to share a single GSM shield :)

Key.Zone
Inspired by various Home Automation Systems. The Arduino devices receive data (via radios) in JSON format and process/react and return in JSON again. Core logic revolves around ArduinoJson. Thanks a lot.

Arduino TFT Forecast Weather Station with ESP8266
by tufantas
http://www.instructables.com/id/Arduino-TFT-Forecast-Weather-Station-with-ESP8266/
This project, builds on Wunderground weather forecast via the Internet. Specs:
- 3 days weather forecast (Low&High temps, probably of precipitation, condition icons)
- Current weather conditions (Current temp, feelslike temp, humidity, pressure)
- Current wind directions & speed with analog gauge meter.
- Indoor temperature with Dallas 18b20 Temperature sensor.
- NTP time via Wunderground time server.
ESP8266 WiFi controlled aircon remote
by beegee1962
This Instructable is about my small project to automatically switch on the aircon if enough energy is produced by the solar panels.
Windows Virtual Shields for Arduino
This project lets an Arduino sketch control a device running Windows 10 - be it a PC, a Windows Phone, or even a Raspberry Pi 2. The only code you write is to an Arduino sketch.

WiBo - Wifi Bootloader for STM32
by Lieven Merckx
Target is to create a STM32 bootloader interface that permits to reprogram remotely any STM32 that supports BOOT0 bootloader mode. This device should be able to reset the STM32 and determine the boot mode.
Second target is to redirect the UART output to the programmer's PC.
DRO
Matic OS
An Arduino based hydroponics Operating System built for any scale hydroponic farm that wants to go fully automated. The DRO-Matic (automatic hydroponics) has been built to allow users to create, configure and share projects called "crops" by interfacing with an external MicroSD card. A single DRO-Matic crop disk size (SD card) can very, but in extreme instances large crop configurations were found to be under 3MB.
