Arduino Jobs

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 have a motorized TV lift, i am able to control the lift by nodemcu. But now i want to make this device in production as want to sell this module. And my client will easily connect it with google home and alexa, and control the lift

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

Need to perfectly time the LED lights on a cycle wheel to form an arc irrespective of the RPM of the wheel. we expect you to:- - Design the PCB - Provide circuit diagram - Suggestion on better sensors that can be used to perform this activity

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.

I want to design a robot to follow a line using 6 sensors, a gyro sensor, an ultrasonic sensor، attached sample of the map.

the system will comprise a raspberry pi zero with 433mhz receiver to receive code hoping remotes. it will also have 4 relays to controll gates etc when the activated by remotes. The system must have a web interface for managing of remotes and assigning it to different users and 1 of the 4 functions The system must also keep a log of remote presses The web must also have a user management system where only admins are allowed to add / manage users, normal users are only assigned remotes

Make a motor drive a gate open and closed with obstruction sensing.

Project based on IOT and PCB designing. Need a IOT engineer who can design me a compact PCB for home automation project it should be successful with all the elements perfectly placed and should give a best outcome. please look the reference videos pcb gerber file - youtube video- ----------------------------------

I need a photo taken that is triggered by motion detection. The photo needs to be sent to any cloud.

I made an RGBW led lamp and I want an Android App and a iOS App able to receive udp messages and control the lamp and groups of lamp trhough udp messages. The lamp firmware is based on ESP32. I made a pdf to better explain how the app should be. The images are taken from existing App like Magic Home or Magic Hue. The use should be quite the same... I'm from Italy so we will need to understand how to test the App without having the light.

Hi, i have an ESP32 device and i found a library that interface with Alexa, the library is Fauxmo, sometimes it works well, some times it does not work well. I can send my code and hope you can find the bug and fix it soon or help me to find another solution. I have to send commands to Alexa and also use the Alexa app To be sure you read all this requirements , when replay start with "Hi Andrea, ..." Thanks

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 realize one software for arduino o raspberry that recognize information during use the toothbrush. All information should be send in one server where I can see it.

I want to create an electronic trigger that is activated by an external source signal. The signal is Manchester code delivered trough a 3.5mm audio jack. (LTC, the end of each frame is identified by a sequence of 12 consecutive highs) The trigger only has to read the signal, display it on a small screen, and allow for a user selectable delay to close a circuit. The trigger will actuate a raspberry pi. I am looking for someone to design and build me 2 or 3 physical triggers. The objective is to create an electronic trigger that is actuated via LTC timecode input. Input Signal: LTC Timecode via 3.5mm audio Jack (the sound is mono, need to check the channel) LTC is a manchester encoded signal, wikipedia has information about it. Each frame end is terminated with 12 highs. I need a ...

RFID based Washing machine & Dryer project. This project is regarding controlling a commercial washing machine & dryer using rfid technology. The data of all rfid’s issued will be stored in a database (aws-light sail). When a user swipes the rfid card the terminal, esp32 which is connected to rfid will communicate with webserver & database & will check if the card is present. Depending on the prerequisite conditions, server will send data weather to run the machine or not. If the user has all pre requisites then data base sends communication to run the cycle. Adjacent link can give some idea. When the server sends data to run machines, then two actions are supposed to happen. Action 1: Send a square pulse of certain wave length. (Will be recorded from one of our mach...
