automatic audio volume control schematic This circuit is used as a series of automatic audio volume control. Audio levels will be in the drive by the voltage of 12 volts 10k ohm resistor connected to the foot differential emitter transistor 2. This series is ideal for users who use the audio volume of digital systems. [...]

This Solar-Battery regulator allows solar cell arrays to be connected to either conventional lead-acid, sealed lead-acid, or lithium storage batteries without fear of overcharging. It allows two different electrical loads to be driven from the batteries at two different charge states to maximise power usage efficiency. The existing power control circuit in this fridge aims [...]
This circuit is uses for the general purpose Big LED with SPI serial interfacing. The circuit is using a serial-in-parallel out shift register, 74HC595 for receiving serial data from microcontroller board. This is the figure of the circuit. For wiring the schematic is SER is for data input, SRCLK is shift clock and RCLK is [...]
You might have seen many videos around you tube showing off crazy LED cubes, forming 3-D structures etc. But haven’t find anything that explains how this is being done. Well searching over internet i found this great project made using a PIC 16F688 microcontroller used to control a 5x5x5 LED matrix cube.
This calculator requires the use of Javascript enabled and capable browsers. A question that often comes up in projects using LEDs is “what resistor should I use with my LED?” This calculator helps determine that for you. Enter the data required for Supply Battery Voltage in the range of 3 to 24 volts, the Diode [...]
