This project requires working with Arduino microcontroller (ESP8266), Stepper motor, motor driver (L289N), 12V battery and a computer/mobile/app interface for input. I will provide for the materials and equipment. Assembly and coding is partly done but I can not get the motor going and need help trouble shooting/diagnose and fix the problem. Project requires the assembly and coding to allow the motor to perform continuing cycles of rotation, following the input via an interface (computer/mobile app). · A cycle is when the stepper motor goes to a preset angle of rotation (steps) at preset speed and reverses/returns to zero angle of rotation. · Cycle starts in anticlockwise direction. · &n...

Hello I have the details of the design which I have to implement in Matlab. Please apply if you have the required expertise. No teams or companies please.
Hi. I am looking to send 8 pairs (16 in Total) of sensor data to MSSQL. This project is to measure the cycle time on an assembly line. Each pair consists of a 24 volt sensor and a 24 volt push button. The 24 volt sensor activation time is the start time and the push button press is the end time. Ideally I would like all 16 sensors to connect to 1 board whether its arduino or Raspberry Pi and send to MSSQL via ethernet. These 8 pairs of sensors span approximately 50 meters. (Will this cause transmission loss?) I have an MSSQL set up already but I am unable to get the data from arduino to MSSQL. I have attached a file.

*****I ONLY WILL READ BIDS THAT START WITH THE WORD "VIRGO" AS ITS FIRST LINE***** We are looking to create a counting system using cameras with a Raspberry Pi. This should have the possibility to change the objects shapes to count and the dimensions using a setup screen. It will have one or more cameras to count at the same time. This interface will have a place to calibrate/adjust/setup the cameras. Also will have to work really fast as objects are falling passing in front of the cameras. Can count objects as small as a ball of a bearing and as large as a coin but need to have an interface to adjust the threshold as how big and how small you want the object. Also we want the system to have a setup page for different I/O for setup.

I have a COB LED 50W Lamp Light 12V Circular LED Bulb powered by a 12V battery. I also have a ARDUINO MEGA 2560 (if needed). I would like to linearly increase the intensity through the COB LED with variable programmable time steps. This is used to simulate the sun rising light from dawn so i can't use PWM technics, just analogical. I can handle the programming but i need some help to figure out the hardware.
Solution to use with existing equipment for various functions. Utility and safety. Existing Equipment - Portable and operated by hydraulic actuator which is powered by a 12v lead acid battery. Battery is kept charged by a solar panel. Aim - Incorporate various electronics, contributing to the utility and safety of the existing equipment. Requirements: 1) Incorporate a 2 axis tilt sensor that will actuate a relay, preventing the actuator from functioning if the angle exceeds a limit. The limits to the angle will need to be changeable but not by the operator, only to suit possible alternative configurations of equipment's weight distribution in future. 2) GPS - Tracking periodically via web or app. Location history. 3) Battery voltage detection - Ability to check via web or app...
Ultra-long range Outdoor-Waterproof RFID Fixed Reader 50M + to cover outdoor area There is a technology called "Passive RFID Tags" applied to metal surfaces", that once they touch metal products turn the product into an antenna. I mention this because I need to track incoming and outgoing employees with the metal equipment and tools they are carrying in a large Waterhouse and outdoor field area. The Reader must be able to read "Passive RFID Tags" that are hidden or printed on the metal. This means that the Tags have to be as small as possible to be able to hide them in Metal gardening tools (Shovels, Trowels, Spades, Lawn Mowers), and at the same time to turn this metal item into an antenna, as mentioned before, I repeat this because the use of a Long-range RFID r...

Use two single-bit inputs and the on-board LED as an output. Write a program that reacts to the inputs and the past states of the inputs. Denoting the two inputs by 0s and 1s, let your program activate different tasks given the input sequence, say, the state 11, followed by 10, followed by 00, etc. The inputs may be connected to wires that you can touch to VCC or Ground terminals of the board.

Utilizing technology used in the automobile industry, I would like to develop a radio frequency prototype for location tracking. Automobiles use key fobs for starting a car when the key fob is anywhere within the vehicle. I would like to use this or similar technology. I am not interested in the aspect of the key fob that does remote start or opens the doors from 100 yards away. I am interested in the aspect of the physical presence of the key fob within the car and how the car recognizes the fob to be present (trunk, front seat, back seat - none matter as the car starts no matter what). Utilizing this technology, I would propose to build a prototype device using existing technology to serve as a local tracking device. For instance, with this device - we would be able to determine if...
