we are producer of IOT security devices and like to enhance the products by ISM Band Temperature sensor connected to our IOT devices. Design and layout of 868 MHz Temperature/humidity sensor unit including layout and firmware. Battery operated 2 year with CR2032 (soldered). Sending every 7 s Data. Data acknowledge (so need transmitter) Temperature sensor -20°C + 70°C + Humidity sensor Capable to be calibrated by software. Expandable to enable additional 3d acceleration sensor to be integrated on board as option. Option for PIR Sensor with light detection sensor. Sensor is connecting to IOT Modul. Self connecting. Sensor has UID. Up to handle 128 units with one IOT device (non collision support by statistic modulation duty cycle). low power microcontroller STM + ISM Transmitter + sheet metal antenna. Requirements: electrical engineer with experience in microcontroller and ISM Band RF design + firmware. preferred: experience in battery operated device development for low power design TIMEFRAME: ~ 1 month circuit + PCB design + 2 month firmware + Test + support industrialisation.
Arduino based PLC programmer. Looking for an arduino based PLC programmer . This is a transition from another PLC. No development required. Only SW coding to the new Arduino based PLC platform. Old code available in VB. PLC will monitor and control various live sensors. ( 50 sensors) . NDA will be required before start. Estimated work in total number of hours: 70.
I need someone to convert the driver code to communicate over chip ATM90E36 that's written in Arduino C to Espress-IDF ANSI C (we're using ESP32 MC). The code doesn't need to follow best practices for the mentioned framework, it just needs to work and then I will adapt and make corrections to follow our standard. More about Espress-IDF: [url removed, login to view] The Driver's Arduino Code library: [url removed, login to view] I will try the code using our chip to check whether it was successfully ported. I need all the functions that's available in the original code (Arduino). Thanks.
Good morning, we need a project to make a wireless button that triggers an action on an arduino board using as little hardware as possible. P.S. necessary source code and hardware used.
Hi! I'm an art student working on my final project, and it involves arduino and programming which, I'm not really familiar with. I'm making a campaign about tech addiction for kids, and the arduino will play parts in an ambient media--consider it like an interactive installation. What I want to make is an automated video which will change according to proximity where the people will stand. Example, if the person is 1m away, video A will play, but if they're getting closer to 0.5m, it will automatically change to video B. I already did research on arduino and currently working with arduino uno and HC-SR04 sensor. I can programmed it to show the distance of the objects, but I can't seem to process that data so it can play the video etc. It's a pretty tight project for it needs to be done by around 12th March 2018, I really hope someone can help me! pretty please.
We are working on nexys video board .We are trying to access DDR3 memory using IP core in Vivado design suit [url removed, login to view] want to read and write the data into DDR3 memory and access it in nexys video board.
connect 3 robots. first robot is man, and the second robot is women and the women follow the man from point A to point B. ( using GPS , and connected by with Bluetooth" send a code from the man to women") robot 3 is a man who is moving around ( not in Bluetooth range ) and when it reach the first and second robot in some point, he hacking the signal between 2 robots and let the women follow him to point C instead of following the first robot to point B .
Hello we have a pcb board, which should be ok with RFID. Your new updated board will handle RFID and BLE together. Your new Antenna should be a combi antenna. We need circuit design + Antena code. Programming needed to be in atmel studio. We will use same board structure and need to add functionality of program inside. So your job is to add adjust RFID and Implement BLE code and Antenna Design. Please contact me if you have experience in Rfid / BLE setup pcb. We have full code description of total functionality. You have to be able to start from coming week. Im off mainly tuesday to thursday. Budget and Quality depend together so 5 USD is no relevant figure. Thanks for interest
Similar to the hand in the first 3 seconds of this video ([url removed, login to view]) I need a robotic hand that can simply open and close with 5 fingers as if simulating a human hand. It does not need to go as fast as the hand mentioned in the video, but I would like it to be able to close and open at least 50 times per minute. Also I would like the fingers on the hand to be removable.
The purpose of this project is to create a circuit-accurate recreation of a MiniLED display array, using off-the shelf (macro-size) components. This display will feature a large array of monochromatic (blue) pixels (SMD LED's) packed tightly as possible in a 5" and/or 11" diagonal 16:9 widescreen aspect ratios, on PCB. Your work will be invaluable for use by engineers, developers, and in technology demonstrations. Your analog design skills and basic coding are both going to be important here. This task Design a PCB to combine and stack Arduino and multiple sub-components function boards into a robust demo unit. This will support power measurement and portable operation on Battery, as well as USB Cable / AC-power. The major components : - Arduino (Mega) for managing image memory and driving the array - Blue LED array - Image memory - Pixel Storage Cap & Comparator array - Decoder Shift Register - DAC Array - Triangle wave generator - Total Display Array power - Battery - AC-Power/Charging port - Bluetooth or USB interface for downloading images The components must be all SMD, low-profile and readily available eg. in-stock on Amazon, Digikey, Mouser Contractor will : - Develop the software for downloading images to the demo board from PC/Mac - Design a PCB board to host the sub-component boards in a robust assembly - Provide the PCB layout and circuit diagrams - Have the PCB manufactured for 10pcs (invoiced separately, not included in project) - Purchase the components (invoiced separately, not included in project) - Assemble multiple units of the boards + modules - Test the assemblies to verify functionality - Flash the units with the latest firmware, including support for all of the functionality current & planned per the Trello SmartCard Proto project - Post all source-code and firmware binaries, and update tools to ensure continued operation and development All as described and co-ordinated per Milestones maintained in Trello

I would like to make a eletronic roulette with 8 LEDs that can light gradually and sequentialy slow the speed until stop on a random led. We need to have one button to start the roulette, buzzers to sound at the same time that lights.
