    Watch the video first: Hello, our current machine is measuring leather, but it cannot work with today's printers because it is an old generation. What I want from you is to measure the skin passing on a tape with the forehead information from infrared sensors, to process this measurement on the leather (there is a printing mechanism, I will send it in detail if you want, and this measurement can be saved and printed. I'm leaving an article for you to explain how the system is and how it works, with its mathematics and equation. please review the video. Google it this article, I can't put it here Design and Development of LED Based Irregular Leather Area Measuring Machine Rehan Adil you can make using ardunio or raspberry pi

    ESP32 Deep Sleep Wake Stubs 5 days left
    VERIFIED

    Code need to work on Arduino IDE with espressif/arduino-esp32 1.0.6 I need to detect a very fast pulse end moment (10-15ms lenght) but since ESP32 takes +200ms to start up, it's must be done from wake stubs 1. Esp32 it's in deep sleep or hibernation mode 2. HIGH pulse interrupt and wake up 3. Wake stub looking for LOW/Falling 4. Wake stub detect LOW/Falling , take the time into variable and wake up as normal 5. Normal operation, print how many microseconds elapesed from LOW time Note: Your stub code must be boot up in less 10ms, otherwise it will not be able to capture the moment from HIGH to LOW Use what ever gpio number for interrupt (DEVKIT-C) Image included for better understanding

    Hello there! I need someone to help me with a Nextion+Arduino project that I am working on. What I want you to do is to check the files that I have already made using Nextion Editor and Arduino to talk to each other. I'd like you to check them, improve them in terms of looks, operation and help me with what's undone. Basic idea is we have a display and Arduino and we want them to talk to each other all time and make the changes on Arduino side, I also have an I2C based battery fuel gauge IC so I'd like you to help me to track it's SOC as well. If you are someone who has worked with Nextion Displays and can do this, kindly bid. I'd prefer it if you have the display at your end and can test the firmware on Arduino and test the HMI interface on the display parallel...

    Microcontroller 3 days left

    Microcontroller is considered as the backbone of Embedded System& it's most important feature is: "It can think". A Microcontroller looks like a simple electronics chip, but in actual its too powerful (also called Embedded Computer) because its programmable. Using programming code, we can control all I/O pins of a micontroller and can perform multiple functions. Before microcontrollers, DLD gates were used to create logics i.e. adding delays, turning signals ON/OFF etc. DLD is still in practice for small projects but if you are working on big industrial projects, then DLD circuits become too messy & thus too difficult to handle. In below figure, I have added two circuits of traffic signal lights: Left Circuit: 555 Timer is used for creating the LED sequences. Right C...

    Hi, We already have a working recorder which saves wav files to an SD card (CPU already reduced to 80Mhz). Worked great but we need to lower the power consumption (Now: 30mA). I wish to get less than 5mA. Hardware: Digital mic (I2S or PDM) and SD card connected to a ESP32 I am pretty sure it is possible to record wav files in light sleep mode. Here is what i have in mind using I2S in the example. But not 100% sure if that works: - In light sleep mode the I2S interface writes data from the I2S microphone to a buffer (I hope that DMA or any other memory is accessible) - A timer wakes up the main CPU when the buffer is full which writes the data to the SD card - I2S and the main CPU can't have access to the same buffer at the same time. So once the timer triggered. I2S starts writing...

    A closed path is to be followed. For example, A White, Paint filled Shape :: Square , Rectangle or a Circle drawn on floor. All captured Images are to be stitched simultaneously to form a shape of path traced. Simple GUI with start , stop and a 2 picture boxes to display live Image and real time stitched Image of path . Any practical issues at the time of trials must be supported through Any desk or Team Viewer. Stitched Image to zoom in or out depending on number of pictures snapped. Any doubts, Please ask before bidding!!
