Linear LED scale module with 12 LEDs.
Can be used as a voltmeter in a scale with independently adjustable limits in the range 0 to 5V (like 1V to 2V scale, 0V to 0.5V scale, etc).
Power supply: 8V to 12V
Graph: 12 red LEDs **, in dot or bar configuration
Graph orientation: top or side of the module
Input scale low limit: 0 to 5V (manually adjustable)
Input scale high limit: 0 to 5V (manually adjustable)
Dimensions after assembly: approx. 78.5x38.5x19 mm (LxDxH) (LEDs excluded)
** Want other colors? Tell us how many of what colors you want up to 12, in the comments at checkout. The available LED colors are: red, green and yellow.

This circuit is very similar to the simple, fun and easy to build tone generator circuit featured in our article Fun and easy to build buzzer circuit!.
Power Supply: 2.5V to 6V (2 to 4 AA or AAA batteries)
Dimensions after assembly: approx. 31x17x11 mm (LxDxH)
The KIT does not include the wires, batteries, battery holder nor speaker. This is a KIT, which means you get the parts and then need to assemble it yourself using a soldering iron.
Price: 5.90 €
EDuino is a serial Arduino-compatible board, smaller, cheaper and easy to build at home.The main design goal that led us to EDuino was that it's expensive to buy a full-feature Arduino for every project.
Price: 9.95 € (estimate)
Welcome to the wonderful world of sound FX!
This KIT consists of a digital software synthesizer with 2 oscillators (LFO and HFO) which can be connected in Amplitude or Frequency modulation configurations. The oscillators feature several wave types, amplitude & frequency modulation, and others, through knobs.
PWM controller board with UART interface, allowing to speed/direction control DC motors upto 1A, and 4 extra lower power devices such as LEDs (for dimming) and servos.
An excellent companion to a microcontroller based processing board such as the Arduino.
Power supply: 6V - 12V
