DIGITAL ELECTRIC EXPERIMENT KIT FOR EDUCATION

摘要

PURPOSE: A digital electronic learning experimental kit is provided to light up the light bulb or the LED lamp etc, and to understand basic of the electronics by experiencing and learning directly the various principles of the digital electronics by experimenting all kinds of programs. CONSTITUTION: The mother is composed of a plurality of protrusions arranged in constant interval so that function module block, including 2 terminal block(110), 3 terminal block(120) and the module block(130), be combined and formed. The motherboard has the control part upon the top unit, and the block connection point in the outside. The control part is composed of: a stereo speaker installed at the left and right; a switch(1) in which the power is supplied or secluded; LED power display lamp displaying the charging state of the battery; a witch selecting speaker and amplifier; a circular volume control part of jog dial function controlled by turning the intensity of AMP; a GND terminal power supply terminals(8,9) supplying the power source of 9V or 5V; a voltage check terminal checking voltage; and a conduction test terminal for the conduction test. In the lower part of the control part, the speaker input terminal(7) which is connected to the selection switch, and the amplifier input terminal connected to amplifier, the middle supply terminal middle-supplying the power of the power supply terminal, and GND terminal(13) are formed.
