Our project it to program a hay inspection station. it will take a picture that must be analysed then will notify the mechanism to accept or reject the bale. Using an SDK supplied from ICI (IR camera) as well as integration of Ethernet/IP (not yet determined LIB) for communications with a plc. The ICI SDK compiles in VS C++ with MFC. The purpose of the application ,is to determine in an automated fashion ,any area in the target that is out of range of the overall average. You can see from the included pictures, how IR highlights different moisture content, the size and locations would very greatly. The automaton is as follows: PLC determines when to start test. Communicated through Ethernet/IP If Apps determines bale should be rejected , returned to plc ...

I have 2 PLC,s communicating with wireless Modbus RS 485. Slave requires minimal code measuring up to 30 PPS, battery voltage a latching relay and possible count reset command. My intention is to eliminate the Slave PLC. I'm looking for someone who can help me with: (1) I have programs written into 2 PLC,s 1 Master and 1 Slave they are linked via RS 485. (2) They communicate through 2 RS485 wireless transceiver,s The Slave PLC has got a very simple program in it . My task is to move the program in the Slave PLC into a microcontroller. I'm presently using an Arduino UNO for the task I've got the majority of the coding done. In closing, I need someone who has SPECIFIC knowledge in IDEC PLC,s and Arduino microcontrollers.

Have a firmware and I can’t seem to make changes or compil it it needs to be done with CCS apparently or MP lab needing the CCS compiler linked to it……… looking for some help to see if it a firmware issue or a mplab issue ? Also want to make some changes to the firmware. Mcu is PIC16F18875 Would like someone to load my firmware and just see if they get any errors when compiling

The DC-DC module(NCS3S4805SC ) is not working now. I am looking for EE engineer. I attached schematic. He will become a member of PPD Development Team.

The project is to make a design that uses inexpensive parts that are ready available/in-stock for a power converter/controller to drive three phase motor on 48 VDC. The controller will have a microcontroller to implement the control algorithm, and a power converter to perform fast switching three phases (upon switching signals) handling about 1 kW total. The switching scheme will follow classic asynchronous switching with three states: positive, zero and negative.

CX-programmer PLC ladder programming. The proposal file will be given only. Need to build the system on PLC ladder programming and then create a report on it. No format for report. Just a basic report with a State diagram, equations, and screenshots of ladder programming and explanation. Needs to be done in one week.

Hello I need a PLC programmer for GE Fanuc Emerson equipment. We have the box design and details but need a programmer.

I am a craftsman and I need to design a very special profile meter for hand crafted curve on a woodwind instrument. I have some product development experience and need someone who can integrate these tiny sensors with a low cost microprocessor that will give me the ability to drive 25 simultaneous 3 segment LED digital read outs. The system will have to have dead on accuracy up to .001 (one thousandth of an inch). We may have to consider programming a calibration mode. Each sensor will have a tiny probe above it which will vary by about 3 mm.

Raspberry Pi pico ir remote How to recive data from ir led

My name is ahmed , I'm a mechatronics student , I need a python code for my raspberry pi that allows me to inspect the liquid level in bottles and classify them into underfilled, overfilled or appropriately filled based on the picture of the bottle taken by the pi camera on the conveyor belt .

Hi, I'm looking for help assessing & optimizing capacitive touch accuracy across various hardware/software combinations. Specifically, we will work with the Apple iPad Pro & Apple Pencil 2, the Surface Pro 3, and the Wacom drawing tablet. The job will be to help create a scientific system (e.g., miniature experiments) so that we can test these aspects. The goal is for us to optimize the capacitive touch precision in the apple products (specifically within our software) as compared to the other combinations. We have laboratory equipment that can help us in this experimentation and are open to purchasing additional equipment if the pricing is reasonable. I will then conduct the experiments using my setup via zoom meetings. We can make adjustments live, troubleshoot togeth...

We have a fully functional Program which calculates some times using location coordinates and timezone and shows the same on 7Segment Displays. The program currently works on ESP32 without any errors or bugs. For our existing ESP32 program we have used Arduino IDE, We are looking for someone who can port the same to ESP12F. all the work will happen via Anydesk on our computer, Review of our existing code will be possible only after we award the project.

we are looking to develop an AC induction motor controller to deliver 350–800A of output at 24–96V system voltage. This project would involve hardware and firmware development.

I currently have some working code for a zero crossing triac dimmer which works perfectly as 4 channels 4 channels and 4 buttons. Button 1 press 1 turns channel 1 on slowly and button 1 press 2 turns off channel 1 slowly. This works great for 4 channels. I would like to change this to 8ch and work in the same way. I will be using Arduino mega 2560. I have had many hours trying but with no luck.

I want a tracking device with A9G and nuvoton microcontroller. That device will be rechargeable, I want a battery backup of 15 days, which should also be fast and chargeable. You must upload the specific thing on the firebase, latitude, longitude, battery percentage, charger pugged In or not, and device Id. On the side of the hardware, I want that device to be very cheap with good accuracy and smaller in size, I can also change my hardware if you suggest to me any other cheap and better performance. Happy bidding in advace Thanks

Interface made with studio to receive data from arduino and show in a graphics in real time, light some inidcators, capable of print screen this graphics and save the data in a text file, the interface is showed in the pìcture. It just take the value from 3 temp sensors and graphics in the time interval, to a low speed (2400 bps) Only the interfase, because the arduino equipment is working right now and is sending the data you see in the pictures and file text attached.

I need someone to write embedded code in a Microchip PIC16F15243. The design includes a MEMS accelerometer and magnetometer that communicates with the uC vis I2C. The uC will need to process the signals from the accelerometer and magnetometer. The processing is relatively simple, a threshold above the baseline level. The device will operate on AA batteries so the uC and sensors will need to go in and out of sleep mode.
