This assumes a conventional ADSR where the sustain continues at the same level as the decay, till the release ramps to 0. The most common kind of envelope generator has four stages: attack, decay, sustain, and release (ADSR). Set the attack and decay levels of the ADSR. Attack is the time taken for initial run-up of level from nil to peak, beginning when the key is pressed. Decay is the time taken for the subsequent run down from the attack level to the designated sustain level.
In the typical synthesizer, the Attack stage begins when a key is pressed. The Attack stage usually offers control of duration that is, the amount of time it takes to ascend to a high voltage level after the key is pressed. When used to modulate a VCA’s level, this allows for everything from very sudden, abrupt note onsets to slow swells that gradually fade in from nothingness. VCAs have many applications, including audio level compression, synthesizers and amplitude modulation.
After the Attack stage has reached its end, the highest point in the envelope’s cycle, the Decay stage commences. The Decay stage also offers definable duration: in this case, the amount of time it takes to fall from this high level. By using moderate Attack and Decay times and a relatively low, one can create sounds that begin with a swelled attack: a sound that increases in volume, decreases in volume, and then settles in at a low, continuous volume.

Thumb Joystick
This is a joystick very similar to the analog joysticks on PS2 controllers. Directional movements are simply two potentiometers, one for each axis. Pots are 10k Ohm each. This joystick also has a select button that is actuated when the joystick is pressed down. This is the breakout board for the thumb joystick. Pins are broken out to a 0.1″ header and includes 4 mounting holes in the corners.
Mozzi
Mozzi synthesis wave packet double, selects 2 overlapping streams. In a wave packet is a short burst of localized wave action that travels as a unit. A wave packet can be synthesized from, an infinite set of component sinusoidal waves of different wavenumbers, with phases and amplitudes such that they interfere constructively only over a small region of space, and destructively elsewhere. Synthesizer and used a capacitor to store and slowly release voltage produced. He refined the design to remove the need to push a separate button one to produce the control voltage determining pitch and the other to trigger the envelope generator. The envelope generator became a standard feature of synthesizers.
Arduino
Joystick vertical potentiometer a fundamental, joystick horizontal potentiometer a bandwidth, potentiometer centre frequency and a select button that is actuated when the joystick is pressed down a random number.

SparkFun Solderable Breadboard
SparkFun Item: PRT-12070
This is the SparkFun Solderable Breadboard. A bare PCB that is the exact size as our regular breadboard with the same connections to pins and power rails. This board is especially useful for preserving a prototype or experiment you just created on a solderless breadboard by soldering all the pieces in place.

PIR Motion Sensor (JST)
SparkFun Item: SEN-13285
This is a simple to use motion sensor. Power it up and wait 1-2 seconds for the sensor to get a snapshot of the still room. If anything moves after that period, the ‘alarm’ pin will go low. The alarm pin is an open collector meaning you will need a pull up resistor on the alarm pin. The open drain setup allows multiple motion sensors to be connected on a single input pin. If any of the motion sensors go off, the input pin will be pulled low.
We’ve finally updated the connector! Gone is the old “odd” connector, now you will find a common 3-pin JST! This makes the PIR Sensor much more accessible for whatever your project may need. Red = Power, White = Ground, and Black = Alarm.

Humidity and Temperature Sensor – RHT03
SparkFun Item: SEN-10167
The RHT03 is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn’t require extra components so you can get right to measuring relative humidity and temperature.

Telescopic Antenna SMA – 300 MHz to 1.1 GHz (ANT700)
SparkFun Item: WRL-13982
This ANT700 is a telescopic antenna designed for operation from 300 MHz to 1.1 GHz with a total length that is configurable from 9.5 cm to 24.5 cm. Each ANT700 is constructed of stainless steel and features an SMA male connector, rotating shaft, and adjustable elbow.
SMA Connector
SparkFun Item: WRL-00593
PCB edge mount – SMA RF connector. Perfect for prototyping with the GPS and Cellular devices that require an antenna connection. These connectors have a female signal pin and will correctly mate with the original SMA type antennas.
EMF Meter
An EMF meter is a scientific instrument for measuring electromagnetic fields. Most meters measure the electromagnetic radiation flux density or the change in an electromagnetic field over time, essentially the same as a radio antenna, but with quite different detection characteristics. Single axis meters are cheaper than tri-axis meters, but take longer to complete a survey because the meter only measures one dimension of the field. Single axis instruments have to be tilted and turned on all three axes to obtain a full measurement.

SparkFun Alcohol Gas Sensor – MQ-3
SparkFun Item: SEN-08880
This alcohol sensor is suitable for detecting alcohol concentration on your breath, just like your common breathalyzer. It has a high sensitivity and fast response time. Sensor provides an analog resistive output based on alcohol concentration. The drive circuit is very simple, all it needs is one resistor. A simple interface could be a 0-5V ADC. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC. This semiconductor gas sensor detects the presence of alcohol gas at concentrations from 0.04 mg/L to 4 mg/L, a range suitable for making a breathalyser. The sensor’s simple analog voltage interface requires only one analog input pin from your microcontroller.
To calculate estimated peak blood alcohol concentration (EBAC), a variation, including drinking period in hours, of the Widmark formula was used. The formula is:
EBAC = ( 0.806 × SD × 1.2 BW × Wt \ MR × DP ) × 10
Where:
-0.806 is a constant for body water in the blood (mean 80.6%)
-SD is the number of standard drinks, that being 10 grams of ethanol each
-1.2 is a factor to convert the amount in grams
-BW is a body water constant (0.58 for males and 0.49 for females)
-Wt is body weight (kilogram)
-MR is the metabolism constant (0.015 for males and 0.017 for females)
-DP is the drinking period in hours
-10 converts the result to permillage of alcohol
BAC% = Breath mg/L * 0.21
