IR Remote Control Tester Circuit

-
Modern TV and DVD remote controls are using infrared signals to control their functions. When we press the button, the remote control front IR LED emits the intended pulse signal. When the photodiode is received an IR wave from a remote control, the remote control tester circuit is switched on its buzzer and LED according to the IR pulse signal.

This is the second solderless breadboard project on the channel. The previous project introduced the um66 integrated circuit and demonstrated how to build that simple circuit on the solderless breadboard. This project is further demonstrating how to make a multivibrator circuit on the solderless breadboard. Figure 1 is the schematic diagram of the multivibrator circuit and figure 2 is the pictorial diagram of the circuit. Figure 1 If you have difficulty making a circuit by using a schematic diagram. Getting a pictorial diagram help to fix the circuit on the project board.  You can install electronic components on the breadboard according to the graphical drawing components are attached. Figure 2      Item list for the multivibrator circuit. 100Ω Resisters (Brown, Black, Brown)  - 2 10KΩ Resister (Brown, Black, Orange) - 2 5mm Red Colour LED - 2 100µF, 10V Electrolytic Capacitors - 2 BC547 Transistors - 2 Solderless Breadboard - 1 1.5Vx2, AA Type Ba

HOW TO MAKE THE UM66T MELODY GENERATOR CIRCUIT The electronic circuits are used to get alarm sounds to attract human attention. From a long-time ago electric bell, alarm circuits, and buzzers were used to draw human attention and those devices are limited to one type of tone. Sometimes alarms are not appropriate to the installed location and the purpose in which it has been used. Presently circuits are used melody generators to make a suitable sound. The UM66T Integrated Circuit is a common melody generator. This Integrated Circuit is based on CMOS LSI design and its melody is stored in 62-note ROM (1) memory. (note: The IC ROM size is changed according to its manufacturer.) UM66T Integrated Circuit has a series of packages. According to your project, you can select a suitable IC Package for your circuit. The packages available song series are listed in the following table. According to manufacture, it has code variations such as UM66, FT66, and BT66. I am

How to make the UM3561 siren sound generator

The UM3561intergrated circuit is based on a low-power CMOS LSI design. It is included programmed mask ROM to generate three siren sounds and machine-gun sound.[1][2] Its siren type depends on SEL1 and SEL2 pins voltage levels. The required voltages of IC playing modes are listed in table 1. The typical operating voltage is 3V and its operating voltage range is 2.4V to 3.6V.[1][2] IC operated by an RC oscillator and it needs to fix to the external resistor. The resister pins should be fixed in between OSC1 and OSC2 pins of the UM3561 IC.[1][2] Figure 2 is the three sound application circuits. (1: Police Siren, 2: Fire Engine Siren, 3: Ambulance Siren)It has a three-position toggle (ON-OFF-ON) switch to select the siren sound and a sliding switch is used to power up the circuit. You can select a suitable type of switch according to your required application in your project. ( eg.you can use the Push-button switch for momentary situations) Required item list for th
