Hello, Please visit these 2 URLs. 1) http://www.instructables.com/id/ARDUINO-ENERGY-METER/ 2) http://www.homemade-circuits.com/2013/03/simple-dc-ups-circuit-for-modemrouter.html Your job is to mix these 2 circuits. Changes you have to make: For link 1: use arduino nano instead of arduino uno. I dont want to use ethernet shield. All the values have to be put in csv file and sent through usb port to computer. For link 2: You need to optimize this circuit to 12V/5amp DC from solar panel input(controller will be present). Now the arduino nano present in link 1 have to measure the voltage,amp and wh for link 2 circuit: i) electricity used to charge the battery ii) electricity supply in case of power failure from mains (No solar input) iii) electricity supply directly to modem (from solar controller to modem) The link 1 meter should send the values of these 3 cases in every 1 sec. You need to send me all the required parts (in detail with the part number), arduino...

I currently have a temperature display with 10 DS18B20 probes. It is fully functional for my needs. It lists the 10 probes, with the names of each probe location, current/min and max temperatures, and when the probe name is touched, it switches to a historical graph for that probe... This is where the problem lies. My initial spec for the graph was a refresh speed of <1s, unfortunately it seems that with all of the code running this was not possible (according to the previous programmer), and it is currently at >3s. My primary goal, at this point, is to find out if someone else is capable of: A: Working the code in such a way to get that time down to <1s or B: Rewriting the code to get the time down to <1s My secondary goals, if possible: I have recently purchased several ESP8266-07 modules to use around the house for various IoT projects, and I would like to use one of them to have all of the probes/temperatures available online as well. I know that some of the processing...

Hi, I have a project in Raspberry PI. Basically, We need to create small component example : Camera Functionality, KeyPad Support, Lock UnLock, LCD Display, Sensor, RFID, ESP82XX device. These are above following components we need help someone to build basic component setup and basic handshake code example. Do you like to help it every component one by one? I am thinking to use NodeJS / Java language if you know other language or you are comfortable so let me think on it.. Please quote me your price how you wanna charge by perhour or per component. Thanks Nasir Sayed

I want to use the existing wiring system on a motorbike and all its existing sensors but install hardware that can transmit the data via bluetooth to an app so there is no need for the instrument panel. I have seen something similar at https://www.chariotgauge.com/info/#introduction. I am happy if app development is not included although this would be a bonus,

I need a developer that can make a client dashboard using Ruby on Rails for the backend and maybe React or Angular for the frontend. This dashboard must connect with a Spark Core. To you learn more about it just Google "Spark Core" This is very time sensitive. We'd like a basic version done in a week. The more done the better. I might hire multiple freelancers so you will have to work well with each other. Team of around 3-4 maybe. Tech Specs: - RoR - React or Angular Frontend - Spark Core hardware - PosgreSQL database YOU NEED HIGH LEVEL OF JAVASCRIPT CODE AND SOME ARDUINO KNOWLEDGE.

I am looking for someone with PCB Design experience as well as Arduino programming experience. I want to design a 2.4ghz RC Transmitter & Receiver setup. The transmitter will be enclosed with a 3D printed enclosure as well as receiver. I need someone to design the PCB schematic as well as help build it with arduino + program it. A few features that the controller will have are the following: - Lipo battery pack for charging - Can be charged via USB - small handheld controller - programmed in arduino - built in led lights front/rear - cruise control - slow, fast, expert options - 13mph, 20mph, aggressive throttle - option for antennas - no dropping or interference - braking turns on red lights I am ready to start on this project ASAP.

In labview, i'll need a simple program that allows you to control a digital pressure regulator and pump. I have a diaphragm pump which is controlled by it's DC motor. The input voltage controls the flow rate. I also have a digital pressure regulator which can read and interact with Labview to output the pressure waveforms. I need to setup a user interface and be able to control the pump input voltage(1-12V) and also see the pressure waveform change when the pump voltage/flowrate changes through the manual control. The pump controls would be setup through a DAQ or arduino and connect to the computer thru a USB-Servo controller(mini maestro 18-channel). The servo controller can amplify the pump above the 5V DAQ limit. The pressure regulator has a serial cable output that can connect to the USB with an adapter. You would just be setting up the servo controller to adjust the voltage on the pump and write a simple VI to show the pressure waveform when the voltage is adjusted.

hi we need arduino based board design and firmware. you dont need to build bord for us (unless you are in NYC or close) we can just get schematics and we build breadboard ourselves. We need wifi enabled device that had 1620 lcd, with start style buttons to navigate menu. real time clock chip with nonindependent 3v battery. and web server Functionality: form buttons and lcd enter wifi setup, select available network, enter password if needed (all types of protocol configuration needs to be supported) show that wifi connected, go to next menu item and configure tear time clock like 15:30:00 (25h format) have. then next menu shows IP address. Type IP on browser open web server see our clock with option to change it . You can use any WiFi chop you want, i prefer cheap once like one for $2-3 off ebay. chip or module I will need schematics and firmware. If you close to NYC i can pay for assembling breadboard and bringing it to our office

We need your help designing an Arduino + cloud system. We are building a company website to send sketches to one or more of our Arduinos via the internet (NOT within one WiFi network), and we want the Arduino(s) to run those sketches immediately when we send them. Responsibilities include: - Explain to a computer literate, programming-capable person how the system should work. - Write (or find + adapt) code that will help our site communicate with our Yuns. - FIRST MAJOR GOAL: Help us get to the point where we have used a website (we're building one in Ruby on Rails) to send a new sketch to one/more of our Yuns via the internet, which it runs immediately. - BONUS: Can you help us set up our system using simpler hardware? We are currently using Yuns. Can we flash simpler devices like the Teensy + ESP8266 or the Cactus Micro with new sketches instead of relying on the expensive Yun? A couple of secondary considerations: - We would like to be able to add new devices easily...
