This is a measuring resonance of very low frequency (vlf). This video shows an easy way to measure the resonance for coil on very low frequency. The frequency range is between 5kHz-30kHz. this video also provides the circuit that is used to measure the resonance of the coil. On this video, to measure the resonance of VLF coil, the 370ohm […]

This is a video tutorial for Function generator. This video explains how to use function generator and how it works. The function generator is used to generate waveform. The waveform that is can be generated by function generator are sinewave, squarewave and trianglewave. Using the function generator we can adjust the frequency, amplitude and DC offset. The function generator can […]

This is a video tutorial about operational amplifier and super microphone circuit. This video shows how an operational amplifier works and an example of amplifier circuit for microphone. The op amp has five important pins. they are output pin, non-inverting input pin, inverting input pin and negative and positive voltage supply input pin. The output voltage will come out from […]

This is a video of LED’s & Integrated Circuits Tutorial. This video shows how to make flashing box. to build a flashing box we need some tools and accessories, such as circuit board kit, UB5 size jiffy box, solder, soldering iron, and 9 DC battery. Before constructing the flashing box, we must plan about position of the circuit and battery […]

This is a video tutorial of AND/OR gate. This video explains how the AND gate and OR gate works. AND gate has two input and one output. the rule of AND gate is when both input are “1”, the output is 1(on). The OR gate also has two input and one output but its rule is different from AND gate. […]

This video tutorial  is about servo motor that controlled by PWM signal.  There should be two electrical input, one for the power and  another for the control signal (to command a position). This servo motor is very common that can be found in the radio control cars and airplanes. The position of  the servo motor is related with the width […]
