Provide all schematics and code to connect TiWi-uB1 to Arduino Uno. Device must: 1) TiWi-uB1 must receive power from Arduino Uno 2) Arduino Uno must obtain TiWi-uB1's MAC address on startup 3) Adjust the strength of BLE signal from TiWi-uB1 to lowest level TiWi-uB1 datasheet: https://www.lsr.com/downloads/products/330-0132.pdf

This job is for you to provide me with the code described below. I am using Wemos D1 Mini's which are based on the ESP8266. This board will be used as a web server connected to an 8 channel relay module. There will be a web interface with 8 buttons that indicate the state of the related relay and that same button will have the option to change the state of the relay. For example, the button will be colored green and have the word ON when the relay is in the on state, and the button will be colored red and have the word OFF when the relay is in the off state. Pressing the button is what changes the state of that button. This will be on my home network but accessible via the Internet so you'll need to ensure it can be easily configured to do so. There will be multiple Wemos setup in my home so it'll need to be possible to have more than one setup. Please message me with questions or comments. The required time is 48 hours from acceptance of the task. If you (successfully) complete it before then I will give you a bonus of $1 for each hour early up to an additional $20. Communication is very important to me. As the project develops please provide updates and set my expectations correctly. Thank you! -Alan

There is a magnetic encoder AS5040 that outputs quadrature or has a serial interface for reading absolute position. These both connect to an Arduino 2560 Mega (might change to Teensy 3.2). I'm looking for help in tuning PID parameters so that the motor can stop at a specific spot. ... There will need to be a velocity PID in one loop and a position PID is another so that I can control both. One option is to use the Arduino PID library or possibly a State Space Controller like: https://github.com/tomstewart89/StateSpaceControl This is for a robotics project. ... I have a webcam on the robot that you'll be able to see and I'll physically be working with you to help tune it. There are a number of other Arduino related components to the project so there could be more work if this project goes well.

Hi, We have a custom made arduino due size pcb/shield which we need updated. The pcb has a 3 channel, 16 bit ad converter AD9826KRSZ and clocks out 2 different hamamatsu lineair image sensors. ... The 3th AD channel is used to measure temperature. We use an arduino DUE to clock out the hamamatsu’s Current design is made by Protel software so if you use that software or can import that is a plus and let me know.

Hi all, I request your expertise for an interesting Hardware / Software project which could be scalable in a near future. I need 1 expert to set-up a prototype for internet connected speedometer and powermeter. It supposes to build necessary hardware with all relevent sensors to get all variables I am looking for: Watt, speed, distance, RPM. This device could be made of several parts, must be small enough to be fixed to crankset and handlebar. This device must communicated via Wifi to a server to aggregate data. There are several others requirement which could make this project interesting for you like mobile app dev. Hope to find an expert with whom I can discuss in details about this project Micro-controlled cycling speedometer / powermeter (IoT) 1. Functional requirement: Convert traditional indoor cycling fitness bikes into smart bikes to provide end-users with a new performance and sport experience. Vast majority of bikes used in these fitness classes are purely mechanical bikes missing embedded basic performance measurement and display.  It is expected to provide a cost-effective device easily configurable and mountable on indoor bikes which could measure speed, average speed (km/h), distance (km), rounds per minute (RPM), power and average power (watts).  It is expected to get a device which is user-dependent. o a QR code must be attributed to each bike. User must sign-in with a dedicated mobile application, where he could have registered beforehand all necessary information potentially needed for measurements (weight, height, age,…). o Following identification, bikes start transmitting parameters to server for performance measurement calculation. o Smartphone used for identification should display user’s performance information in live. o It’s not expected for the moment to work on UI.  It is expected to get 2 modes of use: individual and collective. o When collective mode activated (fitness class), all devices (bikes) should be connected under same independent session. All bikes are in the same room. o All data are transmitted to server for individual and collective performance display on the smartphone. o Ultimately, we would expect different display on the smartphone (individual) and collective via overhead projection (performance comparison between users, ranking,…)  Second step of development, once hardware and performance indicators are properly aggregated, stored and displayed, it must be considered that application should display historical data and historical comparisons between users of a same collective session. For your information, bike which should be used for the prototype would be like : http://www.nutri-cycles.com/documents/Image/seances-spinning-3.jpg Please let me know feasibility and a rough estimate. Of course, if we decide to work together we'll work on an iterative way. I am not expecting a final prototype just based on one conversation. We'll be able to set-up skype meeting and even be able to travel
