I need to build an application to allow the user to update frimware (.hex file) on arduino without Arduino IDE application to allow users to update the frimware in the future my app updates

Hello I require a detection software that can recognize pieces of paper in rectangle form. The pieces of paper have a different shape (all rectangles), different colors and different sizes (min. 1,5 x 1,5 cm - max. 10 x 5 cm)....are not overlapped to other pieces. The background will be black and all pieces of paper will have a different color then black so that they can be distinguished. Attached is a picture of an example how it may be looking like. The pieces with a green circle do fulfill what i described and need to be detected. As a result the software needs to give x and y coordinates of the pieces of paper. Arduino or Raspberry Pi solutions are preferred. I am looking forward to your bid and to work with you. Payment will be done as a one time milestone at the end of th...

Hi Sadi, do you maybe remember the project you sent a bid with an Arduino and motor controlling for a film developing device? I'll send a picture for the timings and you maybe remeber then... Are you still interested? :-) Cheers, Sami

...1000g load cells) connected to an arduino (Uno or Mega) using the HX711 amplifier. I want the output to be displayed on an LCD in real-time and be able to generate a log file into an Excel sheet and the graphs/plotter too. **I want the load cells input to be read independently, as each load cell is subjected to a different weight and the log file should display the output of each load cell separately** A function for calibration is a must and units of weight in grams are acceptable (other units are welcome too) The wiring diagram can be a simple drawing with description of each pin for easy hookup It is possible that I would add more sensors such as an RPM counter and Temp sensor later on I have the following components (Not sure If all is needed): 2 Arduino boards (UNO...

I am a private person and I need someone who know arduino to help (teach) me in a couple of projects as a beginner. First project is 433 mhz code grabber. The hel will be as a remote desktom helper.

I need someone to make me a simple controller from arduino. I already have a pcb as controller, but i wanna switch to arduino. From components i using 12v dc motor, water level sensor (float switch), piezo buzzer, taster, LED. Function is folowing: When water level sensor gives the signal to arduino, dc motor is triggered for 250 milliseconds. If water level sensor still giving the signal, after 6-7 seconds action repeats. This action can be repeated 3 times maximum. If water level don't start to drop down after 3 attempts of motor triggering, that means something is wrong and instead of motor piezo buzzer must start beeping with folowing led blinking. This condition of beeping last until taster is pressed and loop is restarted. So basically controller have ...

I have a Arduino sketch written that uses the ATMEGA328PM microprocessor that incorporates the Quectel L96 GNSS module. The sketch runs fine, but I require someone with in-depth knowledge of the Quectel L96 device to check my code and optimise where necessary to obtain optimum performance. The device uses hardware and software interrupts and is powered by a 800mAh Li-Po battery.

I am trying to figure out what relays I need to use when I have an arduino that needs to trigger a door solenoid The door solenoid is rated at 12 volts and 60 amps I figured I would need a relay that can handle 12 volts and 70 amps but I am not sure how to control the relay when the arduino mega only puts out 5v.

I like to have someone that i can work with on different projects. ESP32, LoRa, GPS, etc

I work in live stream production and I have a tally system I use: - It switches on a tally light once I press a button on a controller - Signal is sent over a CAT network cable. I am looking to send that same signal wirelessly so camera doesn't need to be cabled - Someone on the forum has suggested it's possible with 2 arduinos, rf modules and a powerbank - Is there anyone who could create this transmitter and receiver for me.

We have a DC fan motor 12v DC with 1 direction at full speed at 0%PWM, then fan stop from 40-60%PWM and fan run at opposite direction/ full speed at 0%PWM. We need some help with programming this. The program enclosed to this project is only for one direction. Please make the Arduino project work with this fan motor. The two buttons is for speed control UP and Down. We want the buttons to work that you can adjust the speed from 0rpm to 100% rpm clockwise and from 0rpm to 100% counterclockwise.

I am doing a project which includes a circuit which operates LEDs, this includes 6 lots of LEDs. One needs to illuminate, once a pressure pad is pressed this will cause the LED that is on to switch off and causing another one of the 6 LEDs to light. This process needs to be able to continue for 3 minutes. The circuit needs to be turned on and off with a remote control.

Hello, I need someone to design a simple one layer PCB for an Arduino project. I have attached some drawings and a simple schematic. I just basically need someone to draw it up in a PCB design software so I can send it out to be manufactured. The components can be shifted around as long as the board stays at 83.5mm x 83.5mm. The 2x resistors will be 1/8 watt resistors.
