An integrated circuit called the IC L8038 is used to produce somewhat twisted waveforms such as sine, square, and sawtooth waves. It functions by adjusting the frequency, which is adjustable between 0.001Hz and 300 KHz using an external timing capacitor and resistor. It is able to modulate and sweep frequencies using an external voltage input. […]

Simple Frequency Divider Circuit
As the name implies, a simple frequency divider circuit is a circuit that accepts a signal at one frequency and produces a signal at a lower frequency. This is accomplished by applying a certain element of manipulation to the incoming signal to lower its frequency. Two widely available digital ICs may be used to construct […]
Simple White Noise Generator Circuit
A easy circuit for a white noise generator is a DIY electrical design that simulates the sound of static or hissing that you would hear when switching radio stations. Applications for this noise include sound effects creation privacy sound masking and audio equipment testing. The circuit takes use of the intrinsic electrical noise that exists […]
Analog to Digital Converter Circuit using IC 555
A simple method of converting an analog voltage signal (from a sensor) into a digital signal (ones and zeros) that microcontrollers or other digital devices can understand is to use an analog to digital converter ADC circuit that uses a IC 555. Because it is inexpensive and simple to construct, it is an excellent learning […]
How to Design Crystal Oscillator Circuit
