I have a linier actuator with optical feedback and pwm control. The goal: To extend and retract between two encoder points user definable in the code. Homing on powerup required. Single momentary button (use a counter for extend and retract?) Details Upon extending the actuator will stop at a defined point with a timed delay, then continues to extend to the final encoder count stop point. When it gets close to the stopping point the actuator must slow for a soft stop. Pressing the button a second time will retract the actuator to a final retracted encoder point, soft stopping as well.

Hello, I need to develop a code for an esp8266 project in which = Read the IR sensor and when active, start the servo motor, when inactive, return to the starting position. (During each status, trigger an LED as well) If the ultrasound is at a distance of 8 cm, it is in a condition to check if the load cell is above 4 kg and if so, activate a led. Check if the weight is still above 4kg after 5 days, if so, activate an LED. Its similiar with this project =

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.

I made an ESP32 receiver-webserver program (ESP-now protocol in Arduino IDE) but what is missing from my code is the following: I want when we make a refresh on the receiver's webpage the data to be preserved (imagine that 10 senders for example send each of them just a string as their own id for being recognized by the receiver and a char message like "free" or "duty" which make the corresponding region-square for the particular sender green (free) or red (duty) on receiver's webpage. What now happens is: If I refresh the page all the squares start from green. I thought as a solution: the senders to send every for example 30sec the last message that they have sent but that means the senders all the time are awaken up (via timer) so as to send again the...

Tengo un arduino UNO R3 con un modulo PZEM-004T para medir potencia de consumo. Necesito poder almacenar esos datos, especialmente la potencia consumida y que el valor se muestre en una pantalla de 3.5 pulgadas conectada al arduino. Necesito configurarle al arduino un botón de reset del valor consumido ya que cada 30 días debo reiniciar el consumo de potencia. Me gustaría que cuando el valor de la potencia consumida sea de 0 a 220 watts el color de la pantalla sea verde, cuando el valor de la potencia consumida sea de 220 a 280 watts la pantalla se ponga color amarilla y cuando sobrepase los 280 watts la pantalla se ponga color rojo. En todo momento el valor consumido también se debe mostrar en la pantalla.

We have programmed lights to turn on and off in our showroom with Arduino MEGA 2560. We need someone to remote into our desktop that is connected via USB 2.0 to the Arduino boards. The contractor that did this project for us no longer does this type of work, so we are trying to hire someone new we can have fix current issues, and can be used for future maintenance work (when we change lights in our showroom we need assistance in changing the icons in the GUI). I would like to set up a video call with whoever we hire, so I can explain the overall situation and how it is set up to the best of my knowledge. As far as the arduino software, and how the GUI is set up and how all of it ties together, we are not experts in this. That is why we need your help!

...answer is yes, then read on: We have a C library that needs to be used in a Swift project. The library's function is to establish secure communication between a server entity and a client entity. The library already contains a demo implementation (for Arduino) in C++ (about 800 lines including comments and boilerplate code) for your reference (it establishes a secure connection between two Arduinos using BLE) We need this C library to be packaged in an existing XCode Project (we will send it to you), using Swift types, and properly memory managed using best practices for manual memory management of the C code. You don't need to expose every single API, just enough interface to be able to write the demo Arduino implementation in Swift excluding an...
