#README This is web interface for home automation using raspberry pi and golang project. Feature:

1. Turn On and Off.
2. Dimming 220v light using slider.
3. Motor speed control.
4. API for turn on and off.
5. Feedback for detecting that the device is actually turned on or off.
6. Sense the current to calculate the estimated power and cost.

The feature will be added for the future:

1. Chart.
2. Schedule turn on and off.
3. Sense the voltage value for better calculation of power and cost.
4. Send voltage and current data to HADOOP for better historical data and analitics using API or Socket programming.

#How to run Several items that being use in this project, make sure you have install this before running:

1. go language
2. gorilla mux (http://www.gorillatoolkit.org/pkg/mux)
3. mrmorphic hwio (http://github.com/mrmorphic/hwio)
4. pi blaster (https://github.com/sarfata/pi-blaster)

to start the web: go run web.go

#Testing Still no unit testing for this project.

#Electrical Schematic See Circuit Folder

Component:

1. Triac BT139
2. Triac driver MOC3021
3. Zero Crossing H11A1 or H11AA1
4. Resistor 1k ohm 1 watt (the value depend on the current but minimum 1 watt)
5. Fuse 3 amps/ 4 amps
6. Lamp 5 watt for test
7. Bridge Rectifier KBJ408G (if using H11A1)
8. Tap the current using ACS712 module, connect the VCC to 5v
9. Convert the ACS712 value to digital value using PCF8591 AD/DA converter, connect the VCC to 5v
10. Use level shifter module to convert 5v to 3.3v before connect th PCF8591 to Raspberry Pi I2C interface

#Beware Careful with the electrical component, make sure it all safe!!! You playing with 110v/220v voltage line.. Careful.. Careful..
