A Really Tiny tiny Cylon

A Really Tiny tiny Cylon

Tiny Cylon is a small kit that creates 10 different LED flashing patterns with 5 red LEDs, an Atmel ATtiny13 microcontroller, and a 4.5VDC battery pack. In other words itís an LED blinky PCB easy to assemble and easy to operate.

7 Segment LED Counter

7 Segment LED Counter

This simple counter can be used to count pulses, as the basis for a customer counter like you see at the doors of some stores,or for anything else that may be counted. The circuit accepts any TTL compatible logic signal, and can be expanded easily.

0.3-1.5V LED Flashlight

0.3-1.5V LED Flashlight

It is a little wisp of a circuit that allows you to drive a blue or white LED from a low voltage. Normally, if you want to light up a blue or white LED you need to provide it with 3 - 3.5 V, like from a 3 V lithium coin cell. But a 1.5 V battery like a AA cell simply will not work.

Fancy LEDs

Fancy LEDs

Here is a small tool able to write symbols or pictures on a screen. As a graphic LCD was too expensive, the solution adopted was to pilot a matrix of Leds. This way, with only some cheap transistors, common red Leds and a 16F628, the project is made possible.

LED Snake

LED Snake

In this Instructables going to show you how to make creation, made up of lots and lots of LEDs, that is snake like shape, the LED Snake. LED snake is 1meter long, but you decide how long yours would be.

10 LED VU Meter Project by LM3915 and LM324

10 LED VU Meter Project by LM3915 and LM324

VUor Voltage Unit meters are often included in analog audio equipments to display a signal level in Visual Units. We are building a mono input VU meter in this project. You can build one pair to use them in stereo mode.

Dot to Dot Programming

Dot to Dot Programming

Sporting an 8bit microcontroller clocking in at a maximum 24MHz and supporting 512 bytes of SRAM, 8KB flash, these rather lackluster specs are offset by four analog and four digital customizable advanced peripheral building blocks known as PSoC Blocks, and the ability to build a crazy small microcontroller project.

Drive Multiple LEDs by Using Only One NiMH Cell

Drive Multiple LEDs by Using Only One NiMH Cell

Using a CMOS 555 timer and a single NPN transistor, you can drive as many as seven LEDs using a minimal amount of voltage and power from a single NiMH AA cell.

Dot Matrix Scrolling LED

Dot Matrix Scrolling LED

This is a Dot Matrix Scrolling Sign. A Dot Matrix Display has an 5x7 led matrix with 5 columns and 7 rows. The display is controlled by the AVR microcontroller. The rows are controlled by PORTB of the microcontroller, while PORTD puts the data on the columns to make the characters.

Skateboard with PIC microcontroller and LEDs

Skateboard with PIC microcontroller and LEDs

It is a modified a skateboard kit, added LEDs to the front and back, added PIC circuit, and covered with a comic book and custom graphics.You get a skateboard with eight white LEDs as headlights ,eight red LEDs as tailights all controlled via PIC microntroller.
