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.

Analog Op-Amp Interactive Tutors

Analog Interactive Tutorials

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.

    Process Control Application

    A Closed Loop Control System is the most important aspect of Maintenance, Regulation and Stability in any Live Process. Nature itself is self regulated in an intricate fashion, a keen observer can notice the subtle controls. In Human Created Industrial systems we have Process control as a complex science. We can start by understanding a Simple One.

    Process Control Application Notes

    When you fill a Bucket with water, You keep an eye on the Level of water, as you open the Analog Tap, which is an equivalent of a Motor operated Valve. Your Eye is an advanced Optical Sensor, which is able to sense the level by the computation in the brain, which in turn operates the muscles of your hand, thru the nervous system. The hand along with the Water Tap is is the Actuator. As the water fills up close to the top, you start reduction of the water flow and keep observing, then as it tops up, you tweak the tap to a trickle. When it reaches the limit you shut off the tap.

    Closed Loop Control Systems

    While you are half way filling the bucket, what happens if you take a short nap, or a friend comes by and you are get absorbed in conversation, the water overflows and goes waste. Then someone raises an alarm after the Runaway process happens. This is of minor consequence, but it is not so in the case of Temperature, Pressure and also many common systems like the driving of an Automobile. Remember the gears, brakes, accelerator to control and steer the car to the correct destination, a Runaway Process causes an accident.
