Dice Project circuit | Next Electronics

Here is the schematic, PC board pattern, and parts placement for a "Fantastic Atom Expander". This circuit produces an "exploding atom" effect using 98 LEDs. The LEDs can be any colour but blue. For a very interesting effect, make one...

Animated LED for Bike Turning Signal

The circuit below demonstrates how to animate a bike turning signal using LEDs. The bike turning signal will blink sequentially from the right side (D1) to the left side (D5). This circuit utilizes a series of light-emitting diodes (LEDs) arranged to...

LED Audio VU Meter Circuit

The LED meter circuit is more compact and simpler than its analog equivalent, making it a common choice in audio equipment. This circuit utilizes the LM3915 integrated circuit (IC) and operates in a logarithmic mode. It comprises a single IC...

19 LED Clock circuit

The clock circuit above uses seven ICs and 19 LEDs to indicate binary coded decimal time. The LEDs can be arranged so that each horizontal group of 3 or 4 LEDs represents a decimal digit between 0 and 9 and...

Automobile White LED Light

Without a dedicated buck converter or white LED driver IC, it is possible to safely drive multiple standard high-efficiency white LED modules using available battery power. To design a circuit capable of driving high-efficiency white LED modules without a dedicated buck...

puff to off circuit

This is a circuit diagram of a simple circuit in which the LED can be activated only by a gust of air. A condenser microphone (M1) is used to detect breath. When the S1 button is pressed, transistors Q2 and...

bicycle back safety light

This circuit is designed to provide a clearly visible light, formed by 13 high-efficiency flashing LEDs arranged in a pseudo-rotating order. Due to its low voltage, low drain battery operation, and compact size, the device is suitable for mounting on...

LED Boost Circuit

The completed board may be driven by voltages between 0.8 and 3 Volts. While the basic design goal was candle-like light from a single cell, the values used were chosen to allow safe operation from 3 Volts so you can,...

Handy Pen Torch circuit

This easy-to-construct handy pen torch electronic circuit features a low component count and utilizes two power white LEDs for illumination. A low voltage (4.8V DC) supply is sourced from a built-in rechargeable Ni-Cd battery pack, which is converted into two...
