This is a video tutorial about potentiometer. This video talks about a potentiometer and how it works. Potentiometer is a resistor that its resistance can be varied. The values shown on the potentiometer is the maximum resistance that can be given by potentiometer. In this video, the values is 50K, so the potentiometer can generate resistance from 0-50K ohm. Here […]
Read moreThis is a video tutorial about multimeter. This video shows how to use a multimeter. The multimeter can be used to measure voltage, current, resistance, etc. The multimeter that is used in this video is a digital multimeter. First thing that must be done before use the multimeter is calibrate the multimeter by connecting each probe. In this video, the […]

This is a Sine Wave Oscillator circuit. This circuit as known as amplitude-stabilized sine-wave oscillator. It can gives high purity sine-wave output down to low frequencies with minimum circuit complexity. This circuit has a several advantages such as it does not use the traditional tungsten filament lamp amplitude regulator, so the problem problems associated with a lamp such as linearity […]

This is an Automatic LCD Panel Backlight Control circuit. This is a simple low cost implementation of an LED controller. It can compensate for aging effects and the temperature typically found in high power LEDs. This circuit consist of a photocell sensor and The AD5228 so the automatic brightness control can be achieved. The photocell’s resistance changes linearly and inversely […]
