Arduino and S7-1200, Using S7 protocol

I am using arduino mega right now which i would like to replace with arm which can be compatible with same arduino code.I need expert suggestion

Halloween project - have two 12v dc motors and a full H-bridge with PWM and current sensing. Need a program to turn each of the motors in the same direction for ~30 seconds and then each to turn in the reverse direction for ~30 secs. I think this is fairly easy to program but the delay command does not (in my hands) allow both sides of the H-bridge to function in unison. Thinking that millis(s) programming is needed. Can send more details on the H-bridge, although it is not well documented. Need the controller to operate independently and not need a manual switch to change direction. H-bridge description at:

I built an android during lock down. It is about 3 feet tall and has 26 full metal servos. The servo's are connected to two linked PCA9685 servo controllers. I have two Arduino Megas plus one raspberry PI (to control sensory input). It also has LIDAR and voice recognition/ I just need someone to pull all the bits together and program it to be autonomous

I need a simple code in Arduino that reads any new order from woocommerce, and parse the Status of the order (Pending or Completed), and the Product Id. That info will trigger a relay/motor in the arduino. The data needed is available in the "woocommerce_payment_complete". The Arduino will communicate through a ethernet shield. Each Product id will be linked to an arduino pin (relay/motor). Each line of arduino scketch code must have clear comment. The code is very simple actually, so I need someone with ackowledge in PHP and Arduino scketch coding. This is just the begining of the hole project, a technical test to evaluate the executability of the concept. With that in mind, the hired developer will be the developer of all the fu...

I'm working on IoT project. I'm not very technical. I need help to write a python code to allow raspberry pi to automatically connect two Bluetooth devices to specific serial ports rfcomm0 and rfcomm1. and then I want the python script to automatically start on reboot. would require Video call to show everything in details. I might not be very clear about this so please ask me any questions.

I have an ESP32 chip with the code attached. The problem is that it works perfectly when pairing it the first time, but when I restart the chromecast v3 or it unpairs or it also happens that it unpairs the remote control from the chromecast having to factory reset it.

Hi Narayanan, I had trouble to award you, so I deleted the project and created a new one, not knowing that I will be unable to continue chatting with you. Sorry about that. Please let me know if we can continue as discussed. Thank you

We have some pcb water heater controllers we wish to QC test. We want to build a rig that can run through a standard set of inputs repeatedly to simulate actual usage much faster than happens in normal operation. There is a document attached with more detail. Please quote for the development labour time only, we will pay for the hardware components (or potentially build it ourselves under your guidance). We can send parts and collect a solution item via Fedex at our cost but would prefer a freelancer country that is low cost/easy to do this (eg without undue customs difficulties). If there are any questions to clarify please ask.

I'm seeking help setting up a process to upload our programing to an Olimex (Arduino) board using TAG. I have some "TAG" type hardware but I have not been able to connect all the dots. Freelancer must be available during USA business hours.

I have a working prototype using Arduino MEGA, however, I would not like to use an Arduino mega for the final product. I would like to have the circuit converted to without it. It is a very simple project. Possibly extra work if you would like to design the simple PCB as well, of course I'd pay extra!

I am working on a sensor project using SensESP: I am using a Optocoupler to detect current. To start I just need help with CHANGE / HIGH etc

I need help to be able to switch the ports as needed ( I typically read form the huslylens port and later write to the MicroSDcard). I have a huskylens device connected to the Arduino pins 0/1 for serial communication. I also added a MicroSDcard in the ICSP pins of the Arduino board to write / store data. I am able to to this in a loop fashion (see attached code). but when I want to listen to the huskylens and write information from that to the MicroSDcard , I fail. The project is for a Elegoo Smartcar 4.0. I am attaching the shields , a few relevant programs (optional to review).

For this project an Arduino programm is needed which measures the frequency of a speed sensor is measured and forwarded until a certain frequency. For a higher frequency manipulated values must be given to output. Program should be automatically in manipulation mode but should be possible to disable and enable by getting double input high low hig within 2 seconds. pin7 = input enable disable Pin 8 = input sensor Pin3 = Output additional inforamtion and calculations are done and will be provided.

Just like a remote control car . But a little bit change

Je voudrais un Arduino qui coupe (inverse la polarité 12v) le poêle pendant la chute de x° et qui allume (polarité 12v normale)

The pcb design that i made has an small error and i need someone to help me figure out the issue. Its a combination of Arduino Nano MCP328P + MCP2515 CANBUS board but in a smaller size with lots of extra arduino nano stuff removed as i will not be needing it. MCP328P chip and FDTI chip do communicate with PC and all digital/analog in/outs work quite well so no issues there, however the MCP2515 part is not able to receive nor send CANBUS messages so i am guessing within this simple pcb design i made an error that i cannot figure what is.

Se trata de modificar un sktche de Aduino, es incluir el envío de Sms y modificar el tiempo de encendido de un Led

I have written some code in Arduino IDE for the Arduino Nano. I have 3 inputs and 4 outputs. The code I have written works fine, however, I need the motors to ramp up to the desired speed set by the potentiometer when the pedal is pressed and ramp down to a stop when the pedal is released. The ramp time of the motors needs to be a variable I can adjust. All other functions I have in the code need to work as they currently do but with the ramp up/down ability for the motors.

I have a simple NeoPixel Sketch for the Arduino Nano. This is loosely based on the NeoPixel Adafruit buttoncycler example sketch and the tweaking4all examples This sketch cycles through 4 different NeoPixel effects at the press of a button. The button uses the ezbutton library for debounce. The limitations of the current sketch is that I have to wait for each NeoPixel pattern in the cycle to complete before I can press the button and cycle forward to the next pattern. Each pattern has a delay(), which I understand to be not best practice. Sketch to be modified is attached to the Project. Project requirements: Refactor the sketch so that: - Each pattern loops indefinitely (currently each pattern only plays once)

am trying to make a project using arduino or another microcontroller to make the ps4 controller autoplay in fifa ultimate team i have tried to do it by myself using this website but the library is only made for sending data from the controller to the arduino and actually what i want to do is to send data from arduino to ps4 controller then to ps4 console in order to autoplay in fifa ultimate team

I need someone experience in Arduino programming. The job is to create the firmware for an Arduino Nano with multiple simple sensors (LEDs, temperature, buttons, EEPROM, RTC, etc...). You need to be able to code object-oriented (a class for each sensor) and know how to have multiple process running (using timers or interrupts, no delays or halting the MCU). It can also help if you know a lot of open-source libraries that can be used/adapted. Detailed specification will be provided to selected candidates.
