Kimberly has volunteered to lead a second workshop on controlling an arduino using the web using Node.js. In this workshop, she will go over how to replace the USB cord that we used to connect the arduino to the laptop with Wifi. In addition to the items needed for the last workshop, you will also need the following two items available via amazon prime:
1. Elecrow Breadboard Adapter for Esp8266 Serial to Wifi Transceiver https://www.amazon.com/dp/B00YMRLTHA/ref=cm_sw_r_cp_api_yFDSxb12S4R59
2. HiLetgo 3.3v 5.5v Ft232rl Ftdi Usb to Ttl Serial Adapter Module for Arduino UNO https://www.amazon.com/dp/B00IJXZQ7C/ref=cm_sw_r_cp_api_gGDSxbX1GDBVQ
**edit: I'm trying to get confirmation but I think you will also need something similar to this:
3. Esp8266 board https://www.amazon.com/Diymall%C2%AE-Esp8266-Serial-Wireless-Transceiver/dp/B00O34AGSU/ref=sr_1_2?ie=UTF8&qid=1471367447&sr=8-2&keywords=esp2866 (https://www.amazon.com/Diymall%C2%AE-Esp8266-Serial-Wireless-Transceiver/dp/B00O34AGSU/ref=sr_1_2?ie=UTF8&qid=1471367447&sr=8-2&keywords=esp2866)
If you don't have access to amazon prime, then message steve by WEDNESDAY, and I will try to help get you the parts.
