I'm working on a simple project but now need assistance in transitioning to circuits. The current function is with an Arduino Uno, 4 channel relay shield and ac to dc 5v converter. My aim is to replace these with existing integrated circuits and components that would control 4 strings of LED 5mm string lights, about 3.5 watts each. The function needed is that each string would come on (and stay on) in sequence. Once all are on they would stay on for 5 seconds, then all would turn off together. Additional features if doable and cost efficient are 1., to control the speed of the turn on sequence; and 2., Turn off the sequencing to where all the strings are just on and stay on or completely off.

Hello, Your project looks straightforward, I would just need to clarify some details. Do you want to convert your prototype in a single PCB for mass production? Is there any target price for the final product? How would you like to control the speed of the turn-on sequence? by potentiometer? switches? sending commands to the MCU? How would you like to disable the sequencing? by switches? sending commands to the MCU? I'm available to answer any questions you may have. Best regards,

Hello, I'm able to complete your project. If I correctly understand, you need a circuit without Arduino UNO and maybe without a microcontroller. I am a senior Electronic Engineer, with several years of experience with domain areas like PCB design, software and firmware development, networking, information security. Also, I teach Analog/Digital Electronic Instrumentation, and Information Technologies on Technology University (UTEC), for Biomedical Engineering grade. I am very passionate about my work I really enjoy that I do. I look forward to hearing from you. Regards, Alejandro
