A milliamp meter can be used as a volt meter by adding a series resistance. The resistance needed is the full scale voltage reading divided by the full scale current of the meter movement. So, if you have a 1 milliamp meter and you want to read 0-10 volts you will need a total resistance [...]
Description: The idea for this project may have come to me in a flash of inspiration, and its a very simple way to check if a fuse has blown without removing it from its holder. Notes The simplicity of this circuit uses just two components, but with just one resistor and an LED this circuit [...]
Skema Rangkaian Jam Digital The figure on the right is displaying the condition to be displaying 10:32:54 p.m. switching every 500 milliseconds. In the switching time of the actual circuit, it is 1 millisecond. So, all digit sees to be displayed at the same time. The light of the LED is 1/6 compared with the [...]
Rangkaian Pendeteksi Hujan-Rain Detector This rain detector will accord you a heads-up the burning it starts to rain, hopefully giving you time to abutting windows and accompany in possessions. The battery-powered ambit draws around no accepted back the sensor is dry and the accepted burning is low back the buzzer is activated so a brace [...]

Rangkaian Led 7-Segment Interface Circuit The circuit uses a serial-in-parallel out shift register, 74HC595 for receiving serial data from uController board. See example of U5 in the schematic, SER is for data input, SRCLK is shift clock and RCLK is Latch clock. Each data bit is shifted into the register on rising edge of the [...]
2 Way Cross-Over 3500 Hz (bass and treble) This is 2 way cross-over for your speaker system. This circuit will handle 2 speaker that are woofer (low frequency) an tweeter (high frequency). The result will shown as below picture: Here the schematic diagram of the circuit:
