Mikrokontrollor Jobs

I require a PCB compliance test. test will determine if PCB is capable of passing EMC/EMI compliance tests and all relevant tests relating to CE mark and FCC standards. 1: 2 x PCBs need to be tested. 1 is extremely simple with just 6 switches on it. the other is more complex. 2: Timeframe would be as soon as possible. these boards are fairly simple so shouldn't be too difficult.

I am creating a project which will involve two NEMA 17 motors driven by two A4988 Drivers and using the ESP8266 module. The motors are used for horizontal and vertical movements. I want to create a list of 50 processes where each process will specify motor speed and direction for both motors. For eg: Process 1 may involve moving motor 1 for a few seconds, and the motor 2 and then again motor 1 in another direction and then motor 2 and so on. I am looking for someone who has time and is excited to be involved in this kind of a project. Some experience in Arduino is essential. I want to finish off this week.

I have a simple circuit that is a battery operated rgb color switcher that runs on a PIC10F202; When the button is pressed, the single RGB LED changes to the next color in the sequence. When the battery is installed, the unit is on, and when the battery is removed the unit is off. What I need is to have the code modified so that the uController behaves in the following manner: 1 Unit is off with battery installed 2 Button is pressed once 3 Unit turns on with last selected color illuminated 4 Successive button presses will cycle to the next color in the sequence (R->G->B->Y-C->M for example) 5 Unit will stay illuminated in the current selected color until, 6 Long press (2 seconds) will shut the unit off and save the last selected color in memory 7 Operation repeats as above ...

PCB design, manufacture and firmware programming for a heating controller. It will involve multiple inputs and outputs, both digital and analogue, NTC,0-10v, pulse, CT, on-off, power supply, separate high quality touch screen controller, 8 gig SD storage, Modbus master, Lora, Zigbee (connection to Sonoff sensors), Wi-Fi and LAN. It must connect to a website for analysis of data and the ability to upload data and download instructions and update the firmware through the internet. The project will also include the development of the firmware, website apps ect. I do have a precious version written in C as an example. A full description of the firmware will be supplied after a NDA is signed.

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 ...
