It's a "simple" project but with some challenges and functions. The only thing that is needed is the programming, so no hardware! The hardware is as following: - Arduino Nano 3 board - 2/4 buttons - 1 input signal - 2 relay boards - 2 displays TM1637 Option: LED-strip WS8212/WS2812 The following functions are needed: As the title describes its a time countdown on 2 displays (same time on both displays) with 2 options of time by a press of 1 or 2 buttons : 2.40 minutes (160 seconds) and 3 minutes (180 seconds). The displays are showing ”02:40” or “03:00” before start. When the “start” button is pressed or via the input signal, the countdown is started. When the count down is at 10 seconds left, 1 relay is pulsing every second until the countdown is reached and when 0 the relay is on until the same input is triggered or the “stop” button is pressed. The other relay is triggered af 5 seconds after the countdown reached 0 seconds if the input of “stop” button is not pressed. After one of those is triggered the countdown is re-set to the set time (180 or 210 seconds). The following needs to be adjustable: - Both the start times (180/210 seconds) - The relay pulse start time (at how many seconds the relay starts to pulse) - The amount of pulses per second for the relay - When the second relay is trigged (after how many seconds the relay is on when the countdown is 0) Option: When starting up the Arduino the amount of LED is counted , so the length doesn’t matter when the countdown is active or defined in the config. When powering up the LED strip has a starting color. Every time a second is passed “X” amount of LED is switched to the second color and when the last 10 seconds the LED strip needs to flash until the counter is 0. And after the “stop” button is pressed or the input is trigged the led is set to the starting color. The following needs to by set in the config: - Starting color - Second color - The amount of seconds that the strip flashes until 0 And the wiring diagram.

Hello, I am a Telecommunications and Electronics Engineer with deep knowledge in systems with microcontrollers and Arduino. I can make your system using an interactive simulation software called Proteus (from Labcenter Electronics). Proteus has all the components we need (Arduino board, transistors, resistors, relays, LCD 7-SEG lamps, RGB LEDs, etc.). I have developed similar projects. I offer you a guarantee over everybody. I CAN MAKE YOUR SYSTEM BEFORE MILESTONE PAYMENT, this way YOU CAN SEE THE BEHAVIOR OF YOUR SYSTEM BEFORE BUYING IT. I need to know that you will hire me; we can follow the following steps: 1-) We agree on every little detail. I like to spend a lot of time on this step. 2-) I make the system just how you need it, and I send you a video with the simulation (that way, you can see the relays activating, the LEDs changing color, adjust the settings, we can even use an I2C LCD screen that it allows more functionalities and it is only 1 USD more expensive than the one you want to use). 3-) Once you have seen the simulation, if you are satisfied with the system, you make the milestone payment to me, I send you the project, code, schematic, bill of materials, assembly instructions, etc. 4-) You verify the project and release my payment. Please contact me in the chat; you will not regret it. I can implement any logical behavior that you need, giving you the best cost-benefit relationship. Best regards.

Hello, I worked for 25 years, in a University Institute of Technology, as a professor in subjects such as microprocessors, microcontrollers, PLC automation systems. I have created a software that makes it easy to implement graphical interfaces, you do not need to be a programmer to design the interface. In my portfolio you can see a control application in Furnace with heating profile for soldering SMD components. I have designed and manufactured monitoring equipment for Temperatures, Speed, Pressure, and other variables, with modbus protocol, in RS485, through cable or fiber optics, for the oil industry. Embedded systems under Intel Microcontrollers, Microchip and, Arduino platform and C and C ++ languages. I have manufactured a variety of small CNC machines and others for my shop. I can design the equipment PCB for you. I can design the equipment box for you to be 3D printed. I hope you can contact me to send you more information about it. Best regards.
