AC Remote Sensor
A component of the [[Sensors and Controls @ DILC]] Project, Web-Avaiable Aircon Control is a prototype  aircon remote sensor controllable via Web.


Objective:
  To make a prototype that will make a simple Aircon remote control, controllable by PHP.


Components:
__NOTOC__


1. 5 pcs. Transistos (2N3904)
==Components==


2. 5 pcs. Resistors (22K ohms)
*  5 pcs. Transistors (2N3904)


3. PCB


4. Breadboard

5. Wires


6. CD-R KING Universal Remote Control
*  5 pcs. Resistors (22K ohms)


7. Arduino Micro

How to do:


Step I
* PCB


Gather all the components needed and open the remote control carefully. To open the remote, kindly use a drill to open a small hole in the bottom part, else, use the soldering iron to make a hole. Open the remote by pushing through the hole toward the other parts of the remote.

* Breadboard


Step II

In the Board of the remote, you will see black prints. This black prints are very thin so do not try to solder in it becase of erased connections due to excessive soldering. Try to sketch the black prints, then connect it with other black prints as seen in the documentation. (the black prints can be said connected by the means of green thin lines connecting them, try to follow the green lines from the black print chosen, and it will lead to other two or three black prints.)
* Wires  -  "Solid and Stranded"


*  CD-R KING Universal Remote Control


Step III

The needed controls here are ON/OFF, UP, DOWN. If you will notice, this buttons are functioning by the means of two close black prints. Those black prints are needed to be controlled, so it must be connected to arduino. There are only five black prints needed, so we will need only five wires to be soldered. We will solder only the green wires attached to the black prints needed (the green wires are insulated. To erase its insulation, kindly use a sharp thing to erase it and be careful). Solder only the bronze part where the insulation is erased. Be careful when soldering the bronze part, for when you pull it too much, the connection of the bronze will be destroyed. The combination of the left part from “Mode to “Set” is 3,9,6,11,10,11,3,11,10,5,6,5. The right part from “Power” to “Temperature Down” is 3,5,6,9,10,9.
* Arduino Micro


[[File:Arduinomicro final.jpg|150px]]


Step IV


Get the Breadboard and mount up the transistors resistors and wires. The transistor is NPN.  Search for the pin configuration of the transistor (2N3904). The emitter(E) must be connected to the Ground(Gnd), Base(B) connected to the resistor, Collector(C) connected to  the remote control. There are five sets of transistors needed here.




Step V


To connect the collector of each transistor to the remote, kindly pick one of the soldered wires and connect it to the collector of each transistor.




Step VI


To connect the breadboard to the Arduino Micro, connect the Ground of the Breadboard to the ground of the Arduino, the resistors toward the PWMs of arduino. Kindly arrange the connection of the wires frome the remote to the transistor to the resistor to the Arduino.




Step VII


Make the programming of Arduino and codings that is made from the documentation is correctly copied. (kindly  check the serial port).




Step VIII

If it works, kidly transfer the devices in breadboard to the PCB.

Important Steps

  • On the board of the remote, you will see black prints. These prints are very thin so do not try to solder on them because you might destroy the connections. Try to sketch the black prints, then connect the surface with other black prints as seen in the documentation. (The black prints can be connected by the means of green thin lines connecting them. Try to follow the green lines from the black print chosen, and it will lead to other two or three black prints.)


  • The needed controls here are ON/OFF, UP, DOWN. If you will notice, this buttons are functioning on the two close black prints. Those black prints are needed to be controlled, so they must be connected to Arduino. There are only five black prints needed, so we will need only five wires to be soldered. We will solder only the green wires attached to the black prints needed (the green wires are insulated. To erase its insulation, use a sharp thing to erase it and be careful). Solder only the bronze part where the insulation is erased. Be careful when soldering the bronze part, for when you pull it too much, the connection of the bronze will be destroyed. The combination of the left part from “Mode to “Set” is 3,9,6,11,10,11,3,11,10,5,6,5. The right part from “Power” to “Temperature Down” is 3,5,6,9,10,9.


  • Get the Breadboard and mount up the transistors, resistors, and wires. The transistor is NPN. Search for the pin configuration of the transistor (2N3904). The emitter(E) must be connected to the Ground(Gnd), Base(B) connected to the resistor, Collector(C) connected to the remote control. There are five sets of transistors needed here.


  • To connect the breadboard to the Arduino Micro, connect the Ground of the Breadboard to the ground of the Arduino, the resistors toward the PWMs of arduino. Arrange the connection of the wires from the remote to the transistor to the resistor to the Arduino.

In the PHP code, the $comPort = "/dev/ttyACM2" can be seen. Edit this part by changing the comPort that can be seen in the Arduino. Save all the codes and try to run the application.
