CHALLENGES DESIGN OF SWITCHING LED ELECTRONIC DIAGRAM

The LED WEBENCH® online design environment predicts and simulates the response of an LED to constant current while taking into account several potential design parameters that are new to designers of traditional switching regulators.

LMC7101 LMC7101Q TINY AMPLIFIER WITH RAIL TO RAIL INPUT OUTPUT ELECTRONIC DIAGRAM

LMC7101 - LMC7101Q TINY AMPLIFIER WITH RAIL-TO-RAIL INPUT-OUTPUT ELECTRONIC DIAGRAM

The performance is similar to a single amplifier of the LMC6482/LMC6484 type, with rail-to-rail input and output, high open loop gain, low distortion, and low supply currents. The main benefits of the Tiny package are most apparent in small portable electronic devices, such as mobile phones, pagers, notebook computers, personal digital assistants, and PCMCIA cards.

Simple Electronic Lock

Simple Electronic Lock Circuit diagram. There are six (or more) push switches. To unlock you must press all the correct ones at the same time, but not press any of the cancel switches. Pressing just one cancel switch will prevent the schema unlocking. When the schema unlocks it actually just turns on an LED for about one second, but it is intended to be adapted to turn on a relay which could be used to switch on another schema. Please Note: This schema just turns on an LED for about one second when the correct switches are pressed. It does not actually lock or unlock anything!

Electronic Touch Triggered Bistable Wiring diagram Schematic

This is a simple Electronic Touch Triggered Bistable Circuit Diagram. This schema uses a 555 timer in the bistable mode. Touching T2 causes the output to go high; D2 conducts and D1 extinguishes. Touching T1 causes the output to go low; D1 conducts and D2 is cut off. The output from pin 3 can also be used to operate other diagram ( a triac controlled lamp). In this case, the LEDs are useful for finding the touch terminals in the dark Cl is not absolutely necessary but helps to prevent triggering from spurious pulses.

Digital Electronic Dice Wiring diagram Schematic

Simple and digital electronic dice game schema diagram, this is a simple schema. Powered Board Games is a new category of board games they are digital and can be played using a tangible electronic dice. In this schema Six LEDs are arranged to produce a display the same as the dots on a dice. When PBI is depressed, the display is blanked and the oscillator (ICl a, b, c) clocks IC2 at about 1MHz. IC2 counts from zero and resets on seven When PBI is released, the display is enabled and a decoding system (IC3) produces the correct output on the LEDs.

Simple Electronic Buzzer

This is a simple electronic buzzer schema diagram. Cheap and easy to build.
The 555 is used as astable multivibrator operating at about 1kHz and produces a shrill noise when switched on. The frequency can be adjusted by varying the 10K resistor. You may change the 10K resistor with variable resistor.
