This instructable will cover the basic steps that you need to follow to get started with the ESP8266 ESP-12.
A lot of this content is already out there, but I had a hard time getting everything in place, and the different tutorials can cause a great deal of confusion, which is why I have tried to make the simplest setup possible.
Specifically, this instructable will cover how to make the ESP-12 behave as a WiFi client by connecting to your home wireless network and how to send sensor data ( we will send random numbers to test, and will not really be covering sensors in this instructable) to a Thingspeak channel.
The following are the materials we will be using :
3. LM1117 3.3V Voltage Regulator
4. Jumper Wires
5. 5V Power adapter
