We are looking fore someone who is proficientin embedded systems and can write firmware, bootloaders, e squared c code etc. We want to write a bootloader firmware to function on our proprietary PCB allowing us remote access to do updates etc.
Hi I need an electronics engineer to add LoRa to our existing product. I’m hoping we could hack one in just for testing. I will also need help with witty some code to get our existing hardware working with the new LoRa implant. The code is all Arduino based so I think c++. The code can be done by another if you don’t do code but obviously it would’ve good to find someone wh...
I want your advice on where to purchase a water level (pressure) sensor that also can measure conductance and temperature and send this to a unit on the surface that can record these parameters. No design, prototyping or production is required. I want to buy an aftermarket device and I want to use your contacts of suppliers. I DO NOT WANT YOU TO BUILD OR DESIGN ANYTHING. The sensor can be powered...
I would like to develop a small PCB and get it produced Since I am not a professional, I will need some guidance in developing. I ask for help for: 1- electronic schema development for a small household appliance (in positive case, I must be able to pass CE quality certification): - optimal solution have to be checked together; - simple testing firmware included (eg: C, Lua,...

I have a project and my part is to connect Arduino 1 to Arduino 2 via wireless processing.
I am looking for someone for PCB board design for an analog project. I need to control 32 separate analog circuits with Arduino. At the moment the best solution seems to be that Arduino will control multiple I2C DAC’s(minimal 12 bit) that channel the current thru Mosfets to the circuits. At first I will need help to find the correct I2C DAC and test the code on a breadboard. If everything ...

When the MQ2 gas sensor detects combustible gas such as propane / methane => 200 PPM, it triggers the on (1) function and gets the current GPS fix location coordinates and packages this GPS fix location data as a Google Maps hyperlink inside a SMS text message and sends the message to a specified cell number. The program confirms message receipt then resets the gas sensor to 0 or standby mode r...

Just a man with an idea. Updated: January 16th, 2019 I've updated this project description (again) to clarify a few more things. - Bids exceeding $250 will be immediately deleted. - This project is not intended to be mass produced, and I intend on making the files freely available. So I need to keep the costs down or it's just not realistic. I have a very simple and rather small PCB...
