power supply modifications in arduino

Hello

Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. (autopromotion^)) Do you mean a pcb. What software is it made in? Give more info and lets talk. Bid is not final due to lack of detailes for now.

Hi I am interested to your project. I am familiar with electronics, microcontroller as well as PCB design by Eagle. Thanks.

Hi hello Nice to see your project My self vipin i am electronics engineer i have 4 years + experience in hardware designing, power supply design, SMPS, AC to DC converters etc.. I have gone through your requirements, and i would like to work on your project. The work done will be perfect, Look forward to your response. :) Thanks

I am an experienced Electrical and Electronics Engineer living in Cyprus. I am specialized in Microcontrollers ESP3366, ESP32, Arduino, RaspberryPi. I also worked on lots of Matlab and simulink related projects.

Hi, I can build the modification from scratch. Please message me and lets talk. I have more questions to talk. Thank you.

Dear Sir, I am an Electronics engineer and proficient in electronics circuit and pcb design. Please send me a message for sample of my works. Thanks and Regards, Ronel Divina

Sir I can complete your project using TRIAC, I already completed similar type of projects. Please contact me so that we can discuss further. Thank you

I am an experienced SMPS design engineer who is currently operating as design consultant/contractor. I have experience of designing AC-DC and DC-DC converters as well as DC-AC inverters from initial concept to final production for a variety of industrial, railway and LED lighting applications.

hi, I had already worked on touch switch boards for commercial home switches which also can be controlled on wifi, and using relays. this device used a atmel controller and a wifi module , all are powered form a 7$ power solution which gives 2W o/p power at 5v and I/P of 86-256v a.c. 50 or 60 Hz I/P in the size of 33.8x22.2x19mm of size.

I provide you the best circuit with neat labeling and all the required LED'S placed on where one can notice the status of the supply Here ,i provide you the required output voltages for Relays, Arduino MCU ,etc..,based on the requirements of project You will be provided a Circuit diagram in the form of a PDF file -Thank You
