RGB LEDs Colour Mixing Controller

The primary colour circuit referred to as the RGB LED driver circuit includes individual light emitting diodes that were used in the experiment. Given that this circuit combines three LEDs, it provides a gateway for one control such that achievement of the three individual colours could be made. The sensor circuits were used to measure the intensities of light produced from each diode. By amplifying negative output voltage, polarity of this circuit will be inverted by use of an inverting amplifier. Then this voltage is directed to RGB LED circuit above and in practicality, to the inputs of P1C1F872 terminals A/D. The last part of the circuit encompasses the switching control unit specifically made for purposes of switching the controller on and off and thus feeding with lighting instructions. Aims and objectives The major aim of designing a light emitting diode mixing controller is largely for managing and controlling light emitting diodes colour points. It is also responsible for maintaining the controlled light colours to produce desired lighting effects. Another aim is to reduce cases of failed colour lighting in producing the RGB effect. For these aims to be achieved, specific objectives are necessary. Firstly, identification of all required equipment such as LEDs and power sources with appropriate current feeding is made. ...

Super Heterodyne Receiver
All modern television and radio receivers virtually use the principle of super heterodyne. The super heterodyne receiver reduces to the same intermediate frequency value. In order to accomplish this, it requires that the super heterodyne receiver be able to vary incessantly the frequency that is being mixed into the signal in order to keep the same difference (Jerry 1172). This paper will discuss…
