...should be capable of being powered by typical usb from laptop or alternate power supply, but built using usb-c preferably. Input power should range from 5VDC to 30VDC or higher. Adjustable output voltage up to 30 VDC minimum with 16 bit resolution. Adjustable output current up to 2 amps minimum with 16 bit resolution. Preference is to have a socket for the Arduino (embedded Bluetooth and UART) or the ESP32 (embedded Bluetooth and UART) in the case of failure. Drawings, schematics, and GERBER files should be included as well as a bill of materials, along with two working prototypes. Bonus: it would be nice for battery powered, while charging from the same one usb input. Estimated battery life should be calculated for 24VDC at 20 ma load for a period of 8 hours . It would...

We're developing a product which contains an Arduino Nano 33 BLE (). We're using an original Arduino board, not a ...box where a string send from the Arduino to the tablet will be displayed. The Arduino app should - Set up the Arduino as a Peripheral Service - when it receives a string from the tablet, it will send the same string over the Serial port where we can see it on a PC via the Serial Monitor - when it receives a string from the PC over serial, it will send the same string to the tablet over bluetooth. We want - Source code for both the Android tablet and the Arduino. - Support to ensure we can compile the code and upload the code to the tablet and Arduino on our Windows PC (via a zoom call with screen sharing or similar).

Hi Jitendra S., I noticed your profile and would like to offer you my project. We can discuss any details over chat about android bluetooth.

It is an application where a user can select one type of event among several or a generic event to which they can add images, audio...or another technology that competes with them on price and effectiveness. The application must consider that a group of users update their location in real time with the lowest energy consumption. Other users will not constantly update their location and will only do so when creating an event or entering news It is desirable that the application, even in the background, allows the press of a bluetooth button to bring the application to the foreground and trigger a specific event. From the server side, the control of the user's status must be carried out according to the explanations that will be provided to the chosen company. Required platforms...

...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...

Design pcb board with micro controller like Arduino with Bluetooth module can use it to turn on and of cars through bluetooth

Objective is to build the system which can monitor 3ϕ power supply and deliver required power to load. The proposed system is based on STM32 controller for computation and logical execution. Bluetooth is short range radio and LORA is long range radio used in system for communication. EEPROM is used to store system data. LEDs are used for status indication. As wireless IOT device it should operate on battery for communication. SMPS power supply for powering the system. You can find the attachment for more details of requirement. Skills required: - Understanding of embedded system - STM32 microcontroller - Component selection - Power Circuit design / Schematic design - PCB design - RF understanding - Analog/Digital signal understanding - Board bringup firmware with STMcube IDE
