...pictures, silhouettes on a white background, and over the white area displays specific text relevant to the results of the sketch's operating on the variables received from the sensors. The sequence of events is triggered by using this touchscreen to post a query to get the new sensor values. An alternative display is found on the client's Android smartphone, and communicates with the Arduino via Bluetooth. [This method is preferred.] I have built a partly-functional proof-of-concept system, but I prefer to make another one, introducing one module and feature at a time, adding a new sensor or function only when the previous ones are working. The project would progress thus: 1) The nine preformatted .bmp images would be loaded onto the microSD card from the Windows 10-b...

I want to build scoreboards into my ...light and control the scoreboards. I have them set up for 7 segment displays. I intend to put a small strip of 3 LED’s into each of the 7 segments on each number. So there will be two, two digit displays on each board. I would like one controller to control both boards at the same time. Score would need to run from 0-21. I am open to ideas on how to adjust the score. I have considered Bluetooth to iPhone but think maybe an independent hand helps remote would be best. All items I have are 12v. I have a 12v power source as well as 12v LED lights. I have also purchased several Sparkfun Large Digit Driver TPIC6C596 shift registers. I also have a couple Arduino Mega controllers to use on the project. Please let me know if you can...

The purpose of this Statement of Work (“SOW”) is to obtain services in support of the user experience test and evaluation stage of a new iOS based iPhone application. This evaluation stage creates a new iOS app with minimal function screens and implements device peripheral control using the Apple Core Bluetooth functions. All Bluetooth services, structures and parameters will be provided by the client. It is expected the tasks contained herein will require an early to mid-level developer with solid knowledge and experience with Xcode (v13 preferred), SwiftUI and the Apple iOS frameworks and libraries. Basic knowledge of CoreBluetooth is useful yet the Apple examples demonstrate what is needed. The deliverable will be a functional iOS iPhone app meeting the ...
Hi. I have two Adafruit nRF52840's. One is a CENTRAL and one is a PERIPHERAL. The Bluetooth standard for UART is a maximum of 20 bytes per packet transmission. I need someone who can work with me in C++ to design a data transmission system so I can send small or large amounts of data (EG: 8 bytes or 433 bytes) and have it automatically split the packet into equal parts of 20 bytes each so it can be sent from CENTRAL to PERIPHERAL. I am using the Arduino IDE to compile the code. Central (scroll down to 'Full Sample Code'): Peripheral (scroll down to 'Examples'): Thanks.

Bluetooth Low Energy Bluetooth Low Energy (BLE) signals from battery-driven beacons are at the core of the indoor location technology. It’s one of most prominent technologies that has emerged for indoor positioning and has become industry-standard available on most devices today. It uses so-called BLE beacons (or iBeacons) that are inexpensive, small, have a long battery life, and do not require an external energy source. The device (phone/watch etc.) detects the signal from the beacon and can roughly calculate the distance to the beacon, therefore estimating a users indoor location. How does BLE based Indoor Positioning work? 1. Positioning the user BLE beacons are the cornerstones of indoor positioning. With this technology, the device can detect when in range of a...

There are numerous references and applications which receives data in smartphones through bluetooth, our challenge is to create the driver rating for his trip. The driver rating would be get through that stored data came from OBD, the driver rating function is important whereas the stored data is not. So the data stored to calculate the driver rating can be deleted once the rating obtained. The rating is based on trip from point A to B, if storing data is heavy then calculati...
Deliver a working Bluetooth (BLE) App based around the ESP32-C3. App should take advantage of the 32kHz clock to take advantage of low power settings. Hardware can be provided. While not connected, App shall advertise for 2 minutes and 'sleep' for 2 minutes. Then repeat. Sleep is minimum power level. When connected, the App should be set to notify via Bluetooth. The notification should be a 2 byte counter starting from zero. It shall notify every 2 seconds. While waiting to notify, minimum power shall be consumed.
We’re looking for a developer with expertise (i.e. they’ve done similar projects before!) in iOS development and a focus on AI/ML model training and implementation.
