Posted about 5 years ago

$30-250 USD

Paid on delivery
Needs a simple countdowntimer that counts down from 3 minutes and shows the remaining time on the 7" LCD display of a raspberry PI. Timer should be triggered by pushing a button. Every time the button is pushed is should start on 3 minutes again. I want a text on top "Remaining time" and the remaining time shown in green the first 2 minutes. Yellow when one minute remains and red for the last 30 seconds. When the button is pushed it should also trigger an output that can be used for powering a green LED. When countdown to zero is done another ooutput should be triggered that can be used to trigger a red LED. Raspberry is runnin Raspbian and it would be nice if it was programmed in python.

Hello! My name's Jorge, I am an electronics engineer with experience writing firmware for embedded devices. I have worked mainly with open source boards as the Arduino, Raspberry Pi and ESP8266 family of boards. I have read the description of your project, and this is something I can do easily. I have worked with escape rooms implementations using Raspberry Pi, so I have already codes written to activate/deactivate counters using buttons and showing this information on the screen. Please contact me to talk about your project, I'd be glad to help you out on this. Thanks for your time.

Hi there. I have worked with raspberry pi a lot. I build robots for fun and competitions and so I have a really good idea of how to do what you want. I expect it shouldn't take more than a couple days. I have a raspberry pi myself and a bunch of buttons and leds, so I will be able to test most of the code at my end, however, I will need your help to test the LCD. I can either send you the code and you can run it yourself, or I can access your machine using teamviewer and do it myself. Let me know if you'd like me to work on it.

Hello, I have understood your requirements and will DEFINITELY help you with “Countdowntimer” development. I am feeling pleased to share that we have prior experience in Raspberry Pi and Python. We have developed a “Walkie-talkie” like system in Raspberry Pi recently in which they can share any message within a fix radius area without any authentication. I would like to share our previous experience in more detail way in the same domain. I have understood the working process of countdowntimer and the light system as well, However, I would like to have a quick discussion with you to make sure that we both are on the same page and make a crystal clear project understanding. About Us:- We are new here but have 8+ years experience in IT industry along with a tea, of 85+ developers and designers. We have developed 150+ products and worked on different projects including Amazon Alexa, IoT, Raspberry Pi etc. etc. *** We are open to discuss and ready to proceed right away, please ping me PMB for further discussion. *** I am looking forward to hear from you. @@ This budget and time are just an estimation, we will finalize this while project discussion. @@ Thank You Tapan M.

A Python software for a Raspberry Pi shouldn't be a hard job, just send me the details and I will start to work. My offer is very cheap, but that's just because if you check my profile, you will see that it is my first job on this website, but I will make quality software.

I have done similar display projects on raspberry PIs before, when an event occurs e.g the count down completes the program will interact with the Raspberry PI GPIO pins to switch on an LE. I would propose using a simple html5 app to display the count down which would automatically load when the PI starts. The html5 app will look professional and can be customised to your requirements. Interaction with the GPIO pins for the LEDs will be achieved using python scripts. I would really like to help you on this project, I have been a developer for over 15 years, with lots of hands on experience of raspberry PI. I am uk based.
