All necessary voltages and radio control helicopter control signals are obtained from the serial port computadora.ero us we could only program the micro C84, although it was possible to make the reading of the other models of the Microchip. We have not tested if it works with the memories. The circuit, others simple and intuitive, the socket has to insert the microcontrollers (it better be the type ZIF). Resistors (all) are configured as current limiting, preventing damage to the microcontrollers. The integrated voltage regulator allows for 5v from the 12 approximate line data transmissions. The diode acts as a protector of polarity when the data present on the line is one and the voltage is below zero (negative). For the filtering of the 5V power capacitor has had the character 100µF.Generador video with PIC Just one radio control helicopter microcontroller is needed to perform all functions necessary to generate a composite video signal containing the current time (including a real time clock), a grayscale and a scrolling message. With only five resistors connected to the PIC DAC achieves a stable enough to generate the video standard. The circuit is fed by five volts if possible stabilized. It is a good alternative place two cascaded regulators (such as a 7824 and its output, a 7805) to connect the circuit at any point of the stress pathways of a TV. Of course except for high-voltage pathways. But with only one regulator (7805) is sufficient to feed the 12v present in most of the tuners. Given the low power consumption is not necessary to install the heat sink. It is possible that some people may not be able to elaborate the circuit, thus you will note the radio control helicopter system may behave unstable. It's because not being loaded correctly. To correct this, simply place in parallel with the output form a resistance of 75 ohms to force the loading of the system. The switches marked "Hours" and "Minutes" are push-type NA and to adjust the real time clock. Given the versatility of this circuit, it can be placed virtually any development or equipment other than rc models. The counter runs around microcontrollers from Microchip PIC16F84 whose program is responsible for keeping track of the pulses received and displays control and other aspects that will be below. Double trigger input It is about placing one with a push toward the positive (for rising edges) and another with a push into the mass (for falling edges). In both cases the signal may be TTL radio control helicopter circuit is provided to connect it to 5V voltage. Because the anti-bounce system can be configured trigger input can come from a switch as a barrier crosswalk infra red.
