age levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display. One pin changes the display from a bar graph to a moving dot display. LED current drive is regulated and programmable, eliminating the need for current limiting resistors. The LM3915 ²s 3 dB/step display is suited for signals with wide dynamic range, such as audio level, power, light intensity or vibration. Audio applications include average or peak level indicators, power meters and RF signal strength meters. Replacing conventional meters with an LED bar graph results in a faster responding, more rugged display with high visibility that retains the ease of interpretation of an analog display. Here the circuit diagram of simple and easy made battery level indicator. In general, in mobile phones, the battery levels is displayed in dot or bar style. This helps you to effortlessly acknowledge the battery level. On this page we provide a circuit that helps you to recognize the battery level of a instrument from. This is the design diagram of electronic jam. This jam circuit can be implemented in quiz contests in which any participator who pushes his switch (button) prior to the other participants, will get the first opportunity to answer a question. The circuit provided right here allows up to eight participants with each one assigned a. This is a very simple adjustable analog timer circuit diagram. You can...
