I need a program for an Arduino board so that it can generate 2 types of PWM. 1. Space Vector PWM - SVPWM 2. Hysteresis band current control PWM The user must be able to select the type of PWM that he wants and the frequency (1-200 Hz). The frequency will not be changed with a potensiometer because of the noise but from the serial monitor. The system is intented to work with a SINGLE-phase inverter. The Arduino board that will be selected will be arduino uno. The final deliverable should be the arduino code files with extensive comment documentation.

Http POST Requests XML Parsing Buttons that send Http Post Requests Linear Slider Job Description: I need an iOS app made that needs to do the following. 1. XML Parsing a. App will send a Http POST request multiple times a second that will return XML information from an IP address that will be defined by the user. b. XML will be parsed and passed into a small list of variables. 2. Pressing buttons and a slider will send out HTTP post commands with the User Defined IP address inserted into that URL. 3. Linear Slider that will yield values from 0-255. When the slider reaches 255, the direction will invert and that position now becomes 0 4. User will define the IP address of the destination. I need the app below rewitten in xCode. I wrote this program in Stencyl and need it translated into native xCode. [obscured] /app/id978932322

I want to build a 2-bedroom cottage in a remote area where sun is aplenty (Siem Reap region in Cambodia), but where I cannot count on a reliable utility company. Therefore, I need to put together a self-sustainable source of electricity (110V-50Hz) for the lighting, fridge and some electronic devices (TV, radio, computer, etc.). I estimate my needs to require at least a battery storage capacity of 3KW battery storage (looking at the newly-announced Tesla Powerwall, but a bank of gel deep cycle (200Ah) batteries could also do the job. I did some research and found most of the major components I need (PV panels, MPPT charger, batteries, Inverter). I am looking for someone qualified to: 1) Validate my components for compatibility and balance. 2) Provide a more complete BOM, including jump cables, wiring, junction boxes, switches, remote control panel, etc. 3) Draw a detailed diagram of how the various components are attached to one another, with proper minimum distance between them if...
