My project is for an ESP32 data logger and data history display. I need to log serial data from a sensor, which will be displayed in the form of a chart on a html data will then be stored in an SD card for future reference. I am looking for a freelancer with expertise in this project. I have a working sample. The esp32 is on APmode, uses a sd card to store the requested data from a sensor. The ESP32 host a webpage that users can log in and see the data stored, data is pulled from the SD card via http request on a file called data.txt. My problem is as follows: The chart only displays 20-40 data points stored. But if there is more, like weeks or month worth of data points it freezes or re-starts. I figured it has to do with the amount of time the http request takes due to the large amou...

A PIC18F25k22 development board and HD44780 LCD board along with your ICD4, The embedded system has an analogue input connected to AN4, an 8-way DIP switch connected via the SPI bus and an LCD connected in 8-bit mode to POTR B of the microcontroller. The lcd should initially show a two-line message – ‘Welcome to’ on the top line and ‘Embedded Systems’ on the second line. After a short delay this should change to displaying the adc value on the top line and the DIP switch value on the second line with suitable user interface information telling the user what the display is showing.

I'm looking for an expert in Arduino firmware and driver libraries. The goal is to create a library for a variety of sensors/modules controlled by Arduino Nano. We would start with simple modules (buttons,buzzer,accelerometer,…) then next jobs would involve harder ones (Ethernet,oled,wifi,etc.). We already have a few modules done that can be used as template. We are looking for someone who would like keep working with us for more modules in the near future if possible. All your code will be tested with the real modules so you must know how to debug and fix if needed.

I need an Arduino code the test the full write and full read operations for the 24LC512 memory using the Arduino Nano Board.

Hi, I need you to do this: Connect Arduino or ESP32 to somewhere in internet. //I will provide domain, and hosting After even interval of time MCU add random data to the internet database. //I will create the database, and provide credentials The random data is of type float, and char. Make a page that read form the database, and display its content. Make the MCU to read a certain database record, and sore it in its memory. Use ArduinoIDE for programming. This is an introductory project. I will require understandable code, and comments. I may or may not require a discussion on the project. Tx!

Dear sir or madam. I would need help with programming. I already have an arduino program for my design (pcb with atmega328 ic) - it is about temperature regulation and also I use 1.3inch lcd display with ST7789 board for showing data. The problem is that if the screen freezes, it doesn’t refresh automatically and stays freezed (I need to unplug and plug again the power). I would probably need separate program for the screen, which would recognize when the screen freezes and then refresh it. Or do you maybe know any other solution? I hope that someone could help me. Have a nice day! Gašper Vidmar

We are in the end phase of developing several new tabletop products for the professional food industry. We want to create a great user experience for the interface. The first project would be to take over the software from one of our R&D partners - he makes the PCB prototypes and some of the mechanical solutions. Originally we just wanted to use DWIN but as he changed to a Raspberry screen, he programmed something in Python PyQT just as a method of controlling the product. It works, but it needs a talented UX developer to create a far more intuitive and more attractive interface. We would also like to add a language pack. Originally we just wanted to use DWIN but as he changed to a Raspberry screen, he programmed something in Python PyQT just as a method of controlling the produ...

I'm looking for a freelancer to help me connect a Windows 11 PC to an unknown USB device and dump the firmware. It is a handheld device and a USB connection will be needed. The freelancer will need to be able to read and write the firmware from the device. All details should be carefully handled and no malicious data or code should be written to the device or sent over the network. The device should not be damaged or modified in any way. The output of the project will be the firmware for the device which must be isolated and kept secure with the capability to rewrite the firmware back again (or after modification). An ability to decompile/analyse the firmware once downloaded would generate another project of similar worth. At the moment I cannot find any USB drivers for this unit. ...

I am looking for an experienced programmer to create a firmware program for an MSP430 microcontroller, using the Code Composer Studio (CCS) platform.

We have a bottle stickering line where bottles go over a Assembly line where the bottle goes through a product sticker (marked with a laser sensor). when the laser sensor has been triggered a new label will be pushed foward for the next bottle. This system is now broken. This works with a HMI touchscreen. The manufacturer does not respond back, so we need to make a new solution. I am thinking about a arduino/esp32 for the coding. We have relais, the wave a plc controller type: DVP-14SS2 (if even needed) We have a large steppenmotor and a label reading unit (that can be ignored if we use the sole steppenmotor). Can someone help us with this so that the sticker unit can work again. We have many more projects within our company, so it will be a longer cooperation.

We are an office with countless files. To make it easier to find these files in the future, each of them is to be fitted with an RFID sticker. About five rooms are to be equipped with a UHF reader on a Raspberry Pi. At one workstation, it should be possible to assign RFID stickers to files; this should be made possible via a web interface. It must also be possible to search for files via this web interface. This includes the name of the file, the file number and the RFID code. All UHF readers should then be addressed via a "Find file" button and search for the file (or the RFID sticker). The reader that receives the strongest signal should report that the file is in its vicinity. also we need to use a reader with a wide range, probably at lease 5 meters indoors

Hi, I have a small sailing boat which is moored in the middle of an harbour. I would like to monitor using GPRS 2G network (via Telegram) or SMS the following itens: -gps position. -temperature and humidity using the Dht11 sensor. -battery voltage. -water on the bilges. I would need also alerts for low voltage on the boat battery or high bilge water level. I have been successful in measuring the Dht11 output using WiFi and the following tutorial: However can't do it using WiFi. I'm using the TTGO T-Call V1.3 ESP32 sim800l board and dht11 sensor. Would like to continue to use the same hardware in the project. Could you please provide me a quote for the development of the code? Best Regards

Off grid solar station with an inverter connected to an external 3-pin socket need to track how many kWh's are discharged via the plug. Current thinking is tis might be a raspberry pi with a cellular modem, ideally connected to a clamp meter or similar Data sent to an IP address that can be accessed remotely in Excel or similar format. Does this sound achievable? If so, do you have any questions to be able to provide a quote. Ideal person is based in UK and able to help with hardware procurement and testing.

private swimming pools are often cleaned with pool robots. We want to develop a pool robot which can establish the pool size and shape under water (by means of under water sensor) and develop an efficient cleaning pattern. Then automatically execute the program requested (floor, waterline, wall cleaning and everything together). The robot can orientate itself in horizontal and vertical axis, knows it position relative to the pool at all times and can be picked up after job done and hauled out of the pool by the user. Robot can also be individually guided to certain spots/ stop/ start/ turn via remote control superseding the current program. Experience with underwater sensor, ultra sound sensor a definitive advantage, need to see relevant work details which makes me believe you are up for ...
