We have a noise problem on an input monitoring pulses from a counting device. It is counting noise in the background. We need an electronics engineer to look at the datasheet of the sensor we are using and how we have it interfaced to the Arduino input. This circuit operates in an industrial environment and need to be robust. the Engineer needs to look at the setup and recommend a fix.
I need someone who can make a project with the help of pic micro controller [url removed, login to view] will use a smoke sensor and temperature sensor and detect the fire and turn the alarm on. urgent required. only serious bidder bid.

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.
This Proposal is for the development of a proof of concept model of a device (6X) that will connect to and measure the power output from a solar panel and report the energy generated to cloud based services for collection, analysis, and potentially providing rewards for generating the energy.
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.
We need to Save the Sensors (like Temperature, Humidity, LDR ) data store to the database, from that the module/device can operate the Relays to control the temperature. The data sent from the Module/device/Micro-controller using the GSM Modem (like Sim800, Sim900) with the help of Socket Programming (like TCP/IP Protocol, UDP).
Hallo 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
I am looking for a programmer to code my PIC microcontroller to drive a 6v dc motor using a PWM technique - The battery is in series - 3.6v x 2 = 7.4V LiPo 1000mAh The Motor Nominal voltage: 6VDC No-load speed: 13000rpm No-load current: 0.46A Stall torque: [url removed, login to view] Stall current: 11.8A The PWM technique should maintain the voltage at an average of 6V to the motor until the voltage of the battery drops below a threshold value, this will ensure that the motor speed does not drop as the battery discharges on use. You can find attached the design layout of the PCB and microcontroller/driver 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 .

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.
