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. […]

How To Test a Multi-Core Wire using Cable Tester Circuit
A cable tester circuit is a tool used to confirm that a cable is functioning, usually by looking for shorts (wires that are connected incorrectly) and continuity (open wires). A cable tester circuit is particularly helpful when working with multi-core wires, which are cables that have numerous insulated conductors bundled together. This guarantees that every […]
Simple Tachometer Circuit
A basic tachometer circuit is a DIY electrical instrument for determining a shafts or disks rotating speed. We need a tachometer to determine the rotation speed or revolutions per second RPS of a rotating shaft or wheel. This basic tachometer circuit was created using two seven segment display units and a slotted opto isolation module […]
