We would need to create a hardware to sit on a raspberry pi or an arduino and connect to vending machines control boards. We would like to read data from the vending machine through the MDB protocol and send instructions to the vending machine. Above is the requirements. Please don't bid on this project unless you got previous experience with mdb protocol.

NOTE: See attached doc for a lot more detail. TL/DR: Need a simple android application to use with a set of 4 Arduino Nano BLE (or any Arduino with Bluetooth Low Energy) devices used for gathering Temp, Humidity, Barometric pressure, etc.. App needs to be able to pair up to 4 devices, and needs to be able (when button is clicked) to record data sent over (in sequence) to a local SQLite Database that can then be sent via email (App does not need to be able to send the file, user can do this on their own, SQLite file just needs to be saved somewhere easily accessible). Deliverables: * Source code that will compile from Android Studio and run on a Galaxy Note 10 or newer
I want an android application (android studio (java) ) with source code ,that connect with IOT devices(arduino code) and operate the Motor /pump(demo) automatically like if the water level inside tank is upto 90/100% then turn off motor automatically and when water level is upto 10/20% then turn on the motor automatically .also for the user to operate motor manually then on/off button require .
Porting of this application to Arduino: Example port of an end-of-life, similar library for Arduino, same application: The supplier of this library does not support Arduino anymore in its latest products. We have legacy products on the Atmega2560 based on Arduino boards. I want to investigate if a port of the current library is possible. We have 8KB of RAM on the atmega-2560, so this should be sufficient. No double or floating point numbers are used in this application. What I expect as issues? -> avr-g++ version of CPP? Is the supported version high enough for this library? If not, there is a plain-C library

Hello, I'm looking for some firmware engineer who could help me edit cosmetic stuff which is displayed on tft screen through esp32. Previous programmer left the job uncompleted and I need someone to finish it. Also this is long term project and after finishing this stage I will need some more work to do. Also I need to warn you that I have absolutely zero experience in all that engineering stuff
A hydrophonics controller will be connected to esp32 in order to have remote data loging and control, scope attached
Hi macroenergy, I noticed your profile and would like to offer you my project. We can discuss any details over chat. Your qualifications in Arduino and motor control will be needed
Requirements 1. A simple progressive web app (PWA) that can connect to a Bluetooth (BLE) device (this will be a BLE enabled Arduino Nano for testing). Note that connections must be possible for both Android (Chrome browser) and iPhone (using the Connect browser on iPhone) 2. Code for the Arduino to send and receive data via the BLE from a table of event data which contains • A date and time stamp • A number in the range 0-255 (each number representing a different event type) The number will be entered into the Arduino using the serial console, and the date/time need to be assigned automatically in some format (accepting that the Arduino does not have a real time clock) 3. The PWA will receive data from the BLE device in the form of • A device id...
Hello developers I need help coding and arduino and hmi. so can control a motor and a sensor with the hmi. Thanks
Write code to calculate vertical displacement using MPU6050 sensor. Code shall integrate the acceleration on the MPU6050 accelerometers to calculate distance moved in the x, y, z direction. Code shall use the MPU6050 gyroscope to know which way is vertical (i.e. axis parallel to gravity, g). With information from gyroscope it shall then be able to calculate distance moved in the g direction i.e. the vertical displacement . To test the code I will: - lift the MPU6050 1 meter off the ground - the vertical displacement shall read 1 meter. - I will then put the MPU6050 on the ground - the vertical displacement shall read 0 meters. - I will then lift the MPU6050 1 meter off the ground in a different orientation - the vertical displacement shall again read 1 meter. - I will then place MPU605...
Arduino stepper project I need a capacitive touch (like TTP223) which, if hold down for 5 seconds, turns the whole device on and off. i also need a screen (EDO E1473AC63) with three buttons designed, a bar to indicate the battery level and a bar to indicate the stepper motor effort. if the buttons are kept pressed, they activate the stepper motor. the engine starts only if the button on the display remains pressed. if the button is released, the motor stops. There are three because they have different acceleration and maximum speed. acceleration and maximum speed must be set from a smartphone that communicates via bluetooth with device. I also need a function that if I press three fast touches on the display with two fingers, the motor moves to the zero position (the...

Code for arduino needed. I want to the machine to run until ice is ready to drop into container in short. What I want to do is use a sensor (it's just 2 copper pieces like screws) to connect to each other as soon as the ice is thick enough that completes connection to initiate the drop cycle. (contact with ice on sensor should be for 20 seconds incase false reading) After that it should activate a relay that controls the ice drop until it's finished. After ice dropped the sensor disconnects and relay switches off.

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 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...
