    What we have: -Arduino Uno -Arduino sound sensor (http://www.amazon.com/gp/product/B00AF2GB1U/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1) I am looking for a code that is able to do the following: - Read an input from a mic (arduino sound sensor) on an analog port - Create a rolling average of approximately 100 values of the voltage that is output by the sound sensor. - Create a range of values such that when the rolling average is within that range ...

    I would like to make an Arduino system with mp3.sound and 2 LED output. 3 conditions in the program: Either pressing one or two microswitch all together, there is not any output. Release the microswitch, the mp3 sound will play and the red led will change to green. Now I need someone to help me set up the program and hardware part.

    Hello I need a sketch for Arduino that can control two actuators by limiting their end stops fw/bw via pulse counting their travel. Also I know this is really bad in terms of time pressure, but I need the sketch by the end of this weekend. I have tried to gather as much information on the actuators as possible. There are 8 pulses per spindle rotation. The speed of the actuator is 20mm/s The stroke length is 250mm ...

    I am building a temperature control system. The device should detect temperatures of 130C for 10 minutes and then shut off. If it detects 150C there should also shut off. Hardware: 2 Thermocouples will read the temperatures of 2 heating elements. The Thermocouple Analog to digital conversion is done through MAX31855 chip. It will then be processed through the Arduino to control the heaters (with PID controlling) There will be an LCD screen showing the temperature readings of the thermocouple ...

    Hello, I am looking for someone who can draw a schematic to be printed on a circuit board for an electromagnetic sensor. The sensor will use parts from www.digikey.com. I currently have the design working on an Arduino Uno board, but need to have it printed on a custom circuit board. It will consist of: 1. Sensor http://www.digikey.com/product-detail/en/HMC5883L-TR/342-1082-1-ND/2507853 A breakout board for this part with Schematic and Eagle Files already ...

    Need to use ESP8266 Serial WiFi module to transfer data, up to 2 Mbyte, to Android App and save to a file. Use NavSpark Arduino compatible development board to program the ESP8266. Another Android App is needed to receive the data over WiFi and save to a file. Thus two programs are needed: C program for NavSpark and an Android App for smartphone. The data transfer time should be as short as possible. The distance from ESP8266 device to Android ...
