We seek an experienced engineer to enhance the design and build a device that can obtain fingertip photoplethysmography data at a wide range of wavelengths. We have designed and constructed preliminary prototypes based on published information using commercially available parts. An independent contractor who performs this work should have experience in circuit design, microprocessor control of light emitting diodes, laser diodes, and photodiodes, and troubleshooting acumen regarding signal transmission and reception and optimizing signal-to-noise ratio in the device.

Project to be delivered quickly. Do not bid blindly without reviewing the requirements and expect us to have a discussion later. Please ensure your timeline is realistic and you will stick to it. I am looking for a freelancer to create a simple Arduino project that demonstrates the use of an Analogue NC NO switch. Arduino Nano Project 3 1. On start up must be able to assess 6 separate analogue switches during a 10 second window. 2. During the 10 second window a piezo buzzer should sound (beeping on and off) so the user understands the Nano is assessing the switches 3. The Nano should be able to recognise whether the 6 switches have been set in a Normally Open or Normally closed state. This will change after every use. 4. If a NC or NO switch subsequently changes state the ...

This project is to reproduce a 3D model of an industrial rover as a shell for an Arduino car. The are files attached were made in Sketchup 2020. The first is ATV This is a functional model of a 4WD rover. I need this model to be print ready. There should not be anything left inside it. It will be printed hollow. The rover base should be replaced with the second attached file (Arduino 4WD rover base). To get the rover model to fit to the base there will need to be changes to any or all of the length, width and height of the rover. Arduino 4WD rover base cannot be changed, it needs to remain the same size. Include mounting points so that the base can attach to the rover via a metric nut and bolt (probably M4 would work) The final goal is to have a shell that looks ...

...like to have a similar device developed to operate a small wood stove I have in a small off-grid cabin. The device would read the temperature inside the cabin and then regulate a fan attached to the stove to control temperature inside the cabin (i.e. as the cabin temperature drops, the fan speeds up and as the cabin temperature rises the fan speed slows or stops). I’m envisioning a programmed arduino controller that accepts as an input a simple battery/wall thermostat that would provide a set temperature and a constant temperature reading and then as an output it would power and regulate the same fan that attaches to the Flame Boss. I would simply use the Flame Boss controller but the setting to control the smoker does not drop below 100 degrees (which is too high to re...

It should work something like this: I put in a seed keyword and it returns similar related keyword ideas / results and estimated # of searches per month based on that keyword. I must include searches per month AND some sort of "competition" meter. It would be nice if it found keywords and included their respective monthly search volume. It'll need to be integrated into our SAAS that we're in the middle of building (ongoing work that you can help with if you're interested). ***My budget is $400/month, ongoing.*** I cannot increase it at this time.

Dear Want to build IOT device for AQI monitoring

We need simple software to operate the titrator at the desired rate ( we have the coding from a previous software already), after delivery of the titrate, the system will read the pH meter until a constant reading is obtained, and it will then continue to titrate. The connections from the computer and titrator and pH meter are serial. The data will be saved in a text file. The data will be displayed as volume of the titrate and the mv reading from the pH meter. You can use any software package (MS Visual studio, Labview, Labwindow, etc) to achieve it.

I have an application for meter reading. I am planning to upgrade my application to the latest version of android studio. I want a code on connecting my new mobile printer to my previous application.

Hello, I need an Embedded software developer on the ESP32 to write an Ethernet Library, based on the official esp32-arduino Ethernet Library, to support for a custom RF module. The RF module is connected to the ESP32 through the RMII interface and SPI (for configuration). There is an already existing driver but for the STM32, transmiting data in Ethernet frame format, as SDIO host in SPI mode driver. Deliverables: - Source code for the esp32-arduino Ethernet Library for the RF Module - Example code - Documentation Candidates should have strong development experience on the ESP32 and on writing Ethernet libraries. Thank you
