Prototyping products for the Internet of Things using JavaScript\n\nSource code examples used in my presention on Prototyping products for the Internet of Things using JavaScript\n\n## NFC Card Reader Example\n\nThis example uses an the [Adafruit PN532 NFC/RFID controller breakout board](https://www.adafruit.com/product/364).\n\nConnect `SCL` on the reader to the `B6` pin of the Espruino.   \nConnect `SDA` on the reader to the `B7` pin of the Espruino.  \nConnect `5V` on the reader to the `5V` pin of the Espruino (left of the `3.3V`).  \nConnect `GND` next to the `SCL` pin on the reader to the `GND` pin of the Espruino.\n\n![NFC wiring](https://farm1.staticflickr.com/977/28425769188_4765503bc3_k_d.jpg)\n\n## Display Example\n\nThe example uses three [Adafruit Mini 8x8 LED Matrix w/I2C Backpack](https://www.adafruit.com/product/870).\n\nThey are hooked in parallel:\n\n![Display Wiring](https://farm1.staticflickr.com/902/41407730335_514b9c5e40_k_d.jpg)\n\nThe second display has the `A0` jumper soldered (so it has the address `0x71`),\nThe third display has the `A1` jumper soldered (so it has the address `0x72`).\n\nI use a free MQTT broker from [cloudmqtt.com](https://www.cloudmqtt.com/), copy the file [`./display/cloudmqtt.com/.env.dist`](./display/cloudmqtt.com/.env.dist) to `./display/cloudmqtt.com/.env` and enter your details.\n\nNow you can run `node client.js` in the `./display/cloudmqtt.com` folder.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcoderbyheart%2Fiot-proto-js","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcoderbyheart%2Fiot-proto-js","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcoderbyheart%2Fiot-proto-js/lists"}
