  This project is a sound meter shown by LEDs. It makes use of an electret microphone, op amp, and LM3914 LED Driver IC. How it is used is the louder the environment around the sensor is, the more LEDs are turned on by the LM3914. It’s a fairly simple and interesting project that’s ideal for newcomers to electronics.

  The small AC to DC Voltage Converter project uses four diodes to make one bridge rectifier to transfer AC power to DC power. Also, we use capacitors to remove ripples in the circuit. After we transfer from AC power to DC power, we need to use one 5v voltage regulator to give 5v DC output from 12 v DC output.

  2348 Views

  This project demonstrates the basics of digital logic, the characteristics of a NE555 timer, and demonstrates how binary numbers are counted. The components used are: a NE555 timer, a 12-bit ripple counter, two 2-input NOR gates, a 4-input AND gate, a 2-input AND gate, and a 2-input OR gate. The logic gates, NOR, AND, and OR come in TTL and CMOS equivalents which can be found at Lee’s Electronic. This project is a simple egg timer with two settings: hard or soft boiled and comes with a reset...
