This Instructable will allow you to build a drink coaster with a weight sensor in it. The sensor will determine the amount of liquid in the glass placed on the coaster and send this information through WiFi to a webpage. Additionally, the coaster have LED lights installed that will change color depending on the amount

The main idea was to read in 13.56 MHz RFID (tags / tokes / stickers / wristbands / cards) by a magic box and post the RFID UID to a local database by WiFi network. This instructable builds the base of the whole system – the first working RFID reader on ESP8266 WiFi SoC. (many
The present PROJECT describes a design and implementation of an infrared (IR) remote controlled RoboCar which can be used for various automated unmanned control applications. I have designed remote controlled RoboCar(left-right/front-back motion). The entire system is based on microcontroller (Atmega32) that makes the control system smarter and easy to modify for other applications. It enables
