    I am looking for a talented engineer to make a very simple ardunio solution: Create an ardunio solution that can be used to turn an outlet on or off based on a pre-determined time period, depending on the state: State 1 - Unit is first plugged in / turned on, the unit allows the outlet to deliver power. Goes to State 2. State 2 - After X amount of time (customizable - 1 hour or 4 hours or 2 weeks), the outlet shuts off ...

    Hi, I'm willing to pay $20 to a successful applicant for some of their time and expertise. I need to talk to someone regarding programming languages used for hardware/software interface (automating physical environments), how the software works, electronics used (physical components) and so forth. I would like to get into the business but I have no idea where to start and need some guidance. Applicants should please answer the following questions in their application: Have you developed controller ...

    Would like to make some simple modifications to an Epaper display extension board for a personal project. Simply want to remove some features - some power inputs and some buttons. Also, any changes to reduce the current required would be very much appreciated, though are not necessary. The changes can be seen in these 2 links: Link 1: https://drive.google.com/file/d/0B3eJSQ8x0YKhcU5rT256R0NTYTA/edit?usp=sharing Link 2: https://drive.google.com/file/d/0B3eJSQ8x0YKhekF1eW5SdzhudjA/edit?usp=sharing Details ...

    I am an Art student in Sydney, developing a lamp project. I have code which controls the glow of an LED using PWM over two minutes using an Arduino Uno. I need help in independently controlling two LED lighting strips, with the second operating at a 30-second delay. This can be achieved by code, or using specific hardware readily available in Australia/Online. This needs to be powered by a 230 volt wall socket, stepped down of course. Please find ...

    Hi, We are trying to build a mobile device -which sends sensor data to database over GSM- for the first time. We are using SimCom Sim900R Dual band (900-1800 MHz) GSM module. We developed our circuitry on board using external GSM antenna, and now we want to build a compact design on PCB, which requires an embedded antenna solution. To do this, we have to find a solution for embedded Dual band GSM antenna. We can use small external Ceramic ...
