Digital and Analog Tutors

Interactive Web Widgets that help you learn Basic Digital and analog concepts. You have buttons to press and pots to tweak, LED lights, Digital Displays and Meters indicate output values.

Digital Electronics Tutors

These Digital Tutors are interactive and started with very basic JavaScript and CSS. You can operate the controls and see the Truth Table and Results in LED Displays. Controls include DIP Switches and Push Buttons.

These Gadgets helps beginners learn some digital circuit concepts. The Digital Logic is Studied by operating Switches and observing LEDs on a Virtual Breadboard. Lead Free.


Digital Logic Gates

Gates are what make many of ICs, the two popular families are the 40xx CMOS and the 74xx TTL . Now 40xx come in 74HCT40xx flavors which approach the quality of an ideal gate. Entire circuits with Gates can also be also be burnt into PLDs, FPGAs and CPLDs just like you burn your CDROM. Gates can also be implemented in assembly language which a microcontroller like 8051 will understand and execute.

Digital Interactive Tutorials
Analog Electronics Tutorials

These are analog opamp tutors. Interactive Tutorial with Simulated Meters and Potentiometers, demonstrating how Operational Amplifier functions in different configurations.

Opamps are the Building Blocks of Analog Circuits. Opamps are internally made of Transistor Amplifier Circuits. Now FET and MOSFET Opamps are of greater importance due to better impedance and bandwidth.

Here are some Interactive Analog Opamp Tutorials that i have made using JavaScript and CSS. You can operate the controls and view the results in Virtual Meters and Sources.

Interactive Tutorials using Virtual Electronic Components

Slide the Potentiometers just like you would operate a Sliding Control. Drag the Knob on Pot to increase or decrease the resistance. The Resistance is shown is blue letters and dynamically alters value as you slide the pot.

The mV Source is varied by just moving mouse pointer over the two buttons, no clicking. This reduces finger strain and also you have a long lasting mouse. The mV buttons are special, the variation picks up speed if you let the mouse pointer remain on the button. This is Ramp-up and Ramp-down. This enables you to set it faster with just two buttons.

Finally you have a DVM a Digital Volt Meter that just Displays the Voltage at any Point, this readout value has to be noted down.

Elektrick Power Jedi - Charge Minds with Electricity



The Solderman has been replaced by "Elektrick Power Jedi"

I only hope he gets more young minds into electronics and learning electricity. There is so much of things you can do now. Solar Energy, Solar Cells, LED lighting and Energy Conscious Lifestyle.
