Up Down BCD counter Tutor

See a Tutor Digital up down BCD counter that will help you take the first step in digital electronics.

Counter Lab - The Counter can be tested by clicking the buttons given below, Watch the LEDs and seven segment display. Inc, Dec, and Set buttons are momentary acting and Clk Button is latching  type. The Dip Switch  in the Left also can be set by clicking on each of them, watch the switch and LEDs after a click.

Preset Digital BCD Counter

a. Set the DIP Switch as you like and then Press the Set button.  Now you will see the BCD value in the yellow LEDs named 4029 output. The Decimal value will be seen in the seven segment Display. Now try for different dip switch settings and see the BCD LEDs and Decimal output.

b. Now Press The Inc and Dec pushbuttons and See the corresponding green LEDs which indicate the state of the Nand gate 4093 Flip Flop. Set it to Increment up-count or Decrement which is down-count.

c. Now Click the Clk - clock or count button, the switch will latch, press it again to release.  If you toggle  it once the counter will get a single pulse and it will count it, see the BCD and decimal displays. Now  you turn it on and leave it,  the counter will keep counting one per second till you turn it off, the clock nand gate is wired to be an oscillator.

Electronique - Sonelec-Musique

Theory - This section is for beginners, and explains briefly what are the most common electronic components. Théorie - Cette rubrique est destinée aux débutants, et explique très brièvement à ce que sont les composants électroniques les plus courants. N'allez surtout pas là pour approffondir vos connaissances d'experts !

Electronique - Sonelec-Musique

This topic is for beginners, and explains very briefly what are the most common electronic component. Réalisations - DIY (Do It Yourself, faites-le vous-même). Compilations de montages de mon cru, ou explications et conseils pour des montages d'autres auteurs.

Electronique - Sonelec-Musique - Selector

Electronics - Achievements - Selector 001c

This circuit includes a microcontroller PIC 16F84A type (deprecated) or 16F628A (recommended), and can control one or more devices from eight through some pushbuttons. Each push button corresponds to a separate output, and Pressing either of these buttons activates the corresponding output.

"Drawing used model, designed by Flavie. few overviews and detail. 's eye is made ​​with a ceramic disc capacitor of 1.5 pF. The shoes are made ​​with four small rectangular capacitors of 1.5 pF. For the mane, forelock and tail, I used strands of copper wire. Wire has just been stripped and the copper is still pink. I hesitate to put varnish for protégrer corrosion."

Tutorials on Digital Electronics

These were tutors which i first made at around 1999, improved them many times, it must be bug free by now. Now i ported them to google gadgets too.

Tutorials on Digital Electronics

If you like JavaScript and CSS or want to look at some work i did, study delabs code and
dapj code.

Digital Electronics Interactive Tutors

Both my Electronics Learning and Javascript Learning Have one thing in common, it started by building a Audio Music Player.

Amplifier.cd - measuring instruments - audio

The Content consists of theory, test, analog technique and measuring instruments for amplifiers, electronics and Hifi.

A Tutorial describes fundamental ideas of electro-technology and the general amplifier and audio technology. The test equipment gallery shows measuring instruments - older, historical and partly new.

7A42 is 4 channel Plug-in amplifier

Obsolete Test Equipment Gallery

The 7A42 is 4 channel Plug-in amplifier up to 350 MHz. Conceived for the measurement of logic signals and offers the possibility for triggering the inputs logical AND/OR. So 4 data lines can be observed at the same time on the oscilloscope.
