We are making a robotic lawnmower based on ATMEGA2560 and programmed with Arduino IDE. We have already created a large part of the software, we wanted to know if you are able to integrate some functions such as the management of the Microchip bluetooth (BM71BLE01FC2-0B04AA) which receives commands from a wireless bluetooth controller, such as a playstation 4 controller or compatible and which interfaces with the micro? Furthermore, we would need to know if you are able to integrate the daily programming mode, i.e. decide at what time of day to let the robot go out, for how long to cut and return to base. This by programming via 5-button keyboard and OLED display.

In my project I have 60 stepper motors (28byj-48 5V) I need to control each stepper independently using Arduino board and the input will be or remote or joystick .

Thinking of a small project to first test on an Arduino and then move to a atmega328 or other chip that will need to sense a small micro switch that will be Normally open. . If micro switch shows closed continuously for 120 seconds then chirp sounder until the switch is made to be open again OR a momentary switch has been tripped manually which will reset the timer. Will also need help with being able to move this over to the chip instead of the Arduino and this bid will need to cover the process of what all is needed to make that happen.

...using the WebSocket API are stored in the RAM array, and also sent over the SPI bus to the rest of the system. At powerdown, indicated on a GPIO, the ESP32 needs to save the RAM array to flash. If the file from the pendrive keeps crashing, it should revert to the previous executable which is also saved in the flash filing system. System needs to run fairly quickly so proper C/C++ please, not Arduino, using the official API on the website. Obviously you need to have an ESP32-S3 based module so please don't bid if you don't have one. The standard and S2 based modules aren't powerful enough (tried with a previous Freelancer project before S3 released) I've just put this in the first price range so that people don't just bid the maximum amount but...

I want to control my stove oven with two stepper motors, but my Arduino programming knowledge is only at the beginner level so I hope somebody made an similar project or can program it. Let me try to describe the logic of the program. 1. If I push the K1 Pin on the display, the controller should start an reference drive to setup its end positions. (Status: Reference) 2. Then the stepper motors has to drive to an predefined position (Status: Fire Up) 3. If the exhaust temperature rises over an temperature value for an predefined time, the controller should start working (Status: Normal) 4. Both stepper controllers must work in parallel 5. If the temperature or oxygen values are out of range, the stepper motor should control it 6. If the temperature or oxygen are in range, the stepp...

Hello! I just found this site and decided to try. I'm trying to find a Arduino MIDI specialist. I would need help for writing Arduino MIDI keyboard controller code.
