About thermostat and PIC radio control helicopters systems

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) January 20, 2012 -- There are many operational systems that lead to top radio control helicopters functioning. The thermostat plays an important role. When the temperature falls under the furnace bottom of the setting start and, when so much heat, the heater exceeds the cap will be disconnected.

At first glance the source code looks somewhat complicated by the extensive, but it is very simple to understand. First define the memory locations used and the bits to be used. Then initialize the positions that need it and read from the internal EEPROM's settings. Then initialize the LCD and complete the fixed characters. After the first places the temperature conversion displays the settings. These three parameters (current temp, settings and setup less than) are the only data that is switched on the LCD. Compared if the temperature is below the minimum or connect the relay to disconnect on the maximum. Then remote control keys, if one is driven reacting accordingly.
This step can amplify the power output of conventional VHF handy to 45 watts. At the entrance this system requires 3 watts 45 in order to achieve its output. Thanks to a module, this radio control helicopters system consists of relatively few components.
Circuit

The circuit is powered by 13.8 V, but with 12V also works. It requires about 10 amps of current. The relays allow switching the transmitter off stage leaving the reception mode. For that action is automatic detector has provided a carrier, which transistor switches through the coils of the relays. Relays 1 and 3 should be special for RF and binding of NC contacts must be made with coaxial cable suitable for 144MHz. Not to place the carrier phase detector circuit and the relay would be connected permanently, preventing the reception is possible.
They rely on 2 radio control helicopters controls the RF power module and additionally switch the LED, which is bicolor. In the LED, the anode for the green LED is connected to NC of the relay point for food, while the red anode is connected in parallel with the power of the RF module. The anode is connected to ground with a current limiting resistor. It is mandatory to the LED and its resistance, but looks good and allows you to monitor system status. In contrast, when red indicates that the amplifier is operating (transmit mode).

If we are to use a computer to control, for example, we connect the compressor between parties and close the contacts of the relay. Thus, when the temperature reaches the upper limit it will turn the radio control helicopters compressor.
