Arduino or ESP32 HMI Touchscreen Pump Controller

I need a programmer to write code for a Arduino or ESP32 touchscreen (or similar) which will control a pump to dispense fluid. The touchscreen needs to be used to choose a recipe and then using this data switch a relay for a given length of time which in turn will control a 230v gear pump. The screenshot included shows the basic functionality required. The pump will run at 14 litres per minute and the fluid density is 0.92g/cm³ so the dispensing time can be calculated from the KG value selected. A calibration factor is included for improving accuracy if needed. I require the programmer to recommend the computer and touchscreen suitable for the project.

RF millimeter distance sensor with Arduino Portenta H7

I have RF radar distance sensor from RF Beam and Arduino Portenta H7 . The function of the code is the sensor should detects an object at distance 5 meter an lower ,then the arduino portenta h7 send digital Hi. If the sensor detects a car at 5 meter with specific speed the arduino send hi signal. These data should be stored at the flash memory of the Arduino Portenta H7.

Program Arduino/similar to remotely read/control 0-10v signals

I need to remotely monitor a couple of 0-10v signals, communicating via data SIM to a free online platform such as arduino cloud or AWS (if it has a free tier) I also need the ability to remotely adjust a digital/virtual 10kΩ resistor If you specify the parts, I can buy them and assemble I already have a cheap data SIM, a gsm900 shield and a couple of arduino uno r3s although I don't think they integrate with arduino cloud

Arduino Sensor Processor

Need an Arduino Nano programmed to receive both analog and digital signals from various transducers and set output pins to high or low according to prescribed logic.

Arduino project.

Arduino UNO R4 displays the open or closed state of a door. A reed switch in the door detects the state, which needs to be indicated using LEDs. A red LED indicates the door is open, while a green LED indicates the door is closed. The LEDs must be connected through relays. The same reed switch should also turn on the lighting in front of the door. The lighting operates on 230V power. I only need the code and a wiring diagram for connecting the inputs to the Arduino board. Interested individuals are welcome to contact me regarding the project.

LED Panel Design. Arduino or other.

We are looking to develop a high luminosity through-hole LED panel comprising of a simple fixed text (8 letters). The panel will be used in an outdoor racing environment. Tests on LED matrix panels have proven unsatisfactory in terms of brightness / visibility in sunlight. In total there will be 267 LEDs split as follows: Letter1: 36 LEDs Letter2: 38 LEDs Letter3: 38 LEDs Letter4: 42 LEDs Letter5: 34 LEDs Letter6: 22 LEDs Letter7: 22 LEDs Letter8: 35 LEDs We are considering using 30000 mcd LEDs but will be guided by the developer: 1) All LEDs should be turned on or off at the same time (there is no scrolling / flashing requirements etc). Simply on or off. 2) The display should automatically turn off after 30 seconds. 3) The design should minimise the amount of manual soldering required. 4) We require recommendations regarding power sources (e.g. 12v 4ah battery etc) Price quoted is negotiable based on experience and speed of execution.

Program Arduino or similar

I need to read 4 x thermistors (10K3A1) and 1 x flow detector (simple switch) in a heating system, and depending on the relationship between the readings, logically control 2 x relays (these will open/shut 230V water valves). I will need to have visibility of the temperature readings and the relay output status, and be able to adjust the temperatures, dead-bands, minimum change-over time etc. I have the sensors and the relays but need advising how to get permanent connections to whichever processor we are going to use, rather than via a breadboard

Modbus points via arduino or similar

I need a device that will let me read some parameters off an air source heat pump. I have the Modbus register and need to read around 20 points and write to about 5. the communication will be via RS485. I'm hoping that this can be done relatively easily with an arduino or similar, so I can read/write the modbus points within the scene. please quote for specifying the hardware required (I will purchase and build) and writing a program to give me what I need.

Remote monitor with Arduino or similar

I need equipment specification and programming to remotely monitor 2 x 0-10v signals, and to be able to remotely adjust a simulated 10k pot I'm thinking maybe an Arduino or Pi? it will need to connect to the internet (ideally through a SIM) and we would like to be able to graph the remote signals as well as view in real time. I'm unsure how we would do this, via a cloud service or something? Please provide a proposal and recommendation for the hardware required, programming, and a web platform to view the results on. Web platform should ideally be free or low cost.
