Task 1: There are 5 white LEDs and 3 regular buttons (non-latching). Button 1 (B1), Button 2 (B2), Button 3 (B3). LED 1 (L1), LED 2 (L2), LED 3 (L3), LED 4 (L4), LED 5 (L5). When pressing a sequence of button combinations, the LEDs light up sequentially. If an incorrect combination is entered at any point, the LEDs turn off and you need to start over. When the entire correct combination is entered, all LEDs light up and blink 3 times, and a relay is activated.

Key combination:

B1+B2 = lights up (L1)
B1+B2+B3 = lights up (L2)
B2 = lights up (L3)
B1+B3+B3+B3 = lights up (L4)
B3 = lights up (L5) + blinking of all LEDs 3 times + relay activates for opening

Task 2: Instead of a button, a reed switch will be used. When the contact closes, an mp3 file should start playing on an active separate speaker, playing to the end and then stopping. After 4 seconds from the start of the audio file, the relay should activate to open the contact. The task resets upon reset or after a 5-minute pause. A sketch file for edits is also needed.

Good day. I have experience in programming microcontrollers, including Arduino. I am ready to complete your order, with current adjustments in case of detecting an error in the algorithm's operation. After clarifying some points regarding the nuances of the algorithm's operation, I can offer an implementation with the possibility of expanding the number of commands or quickly changing button press combinations without altering the algorithm. I will explain the operation of the firmware algorithm, provide the firmware, and the project's source code. I will be happy to collaborate.

Good day. I have experience with Arduino. I will do it quickly and cheaply, as I am gathering reviews. I already have a ready prototype for the first task. Message me privately, and we will discuss the details.

Welcome!
We have extensive experience in developing for Arduino IDE, and we can complete your task on both Atmega328 and STM8/STM32.
We already have an almost finished example of your project (code lock).
If you want to use a modular Arduino structure, we can quickly write the sketch for you. However, if you wish to receive a prototype printed circuit board for the entire device, we can handle that task as well!
We have experience in developing printed circuit boards for any purpose.
Our team includes electronics engineers and programmers, and we can carry out your task at all stages of prototype creation, as well as enhance/improve the electronic circuit if necessary.
We manufacture printed circuit boards (small volumes, specifically for prototypes) at our own mini-production facility.
We look forward to collaborating.
