WeatherClient

A simple sketch that displays the current weather conditions according to worldweatheronline.net on an LCD.

Configuration

You'll need to update five values in src/WeatherClient.ino so they make sense for your environment:

• WLAN_SSID - Your network name
• WLAN_PASS - Password to your network
• WLAN_SECURITY - One of: WLAN_SEC_WPA, WLAN_SEC_WPA2, WLAN_SEC_WEP, or WLAN_SEC_UNSEC
• API_KEY - Your free API key from worldweatheronline.net
• CITY - Either your city and province, or your postal code. Must be URL encoded.

Parts

• 1 x Arduino UNO
• 1 x Adafruit CC3000 Shield
• 1 x 16x2 LCD
• 1 x 3.3 kΩ resistor
• 2 x 47Ω resistors

Wiring

The CC3000 shield uses the following connections:

• SCK -> Digital pin 13
• MISO -> Digital pin 12
• MOSI -> Digital pin 11
• WCS -> Digital pin 10
• VBAT_EN -> Digital pin 5
• CCS -> Digital pin 4
• IRQ -> Digital pin 3

The LCD is connected as follows:

• LCD1 -> GND
• LCD2 -> 5v
• LCD3 -> 3.3 kΩ resistor -> GND
• LCD4 -> Analog 0 (a.k.a digital pin 14)
• LCD5 -> GND
• LCD6 -> Digital pin 2
• LCD11 -> Digital pin 6
• LCD12 -> Digital pin 7
• LCD13 -> Digital pin 8
• LCD14 -> Digital pin 9
• LCD15 -> 5v
• LCD16 -> 47Ω resistor -> 47Ω resistor -> GRD
