I have experience in schematics and PCB design experience in Altium and ORCAD. I am ready to work for you. Please contact for further discussion

Dear Sir, I will prefer to use Meanwell led driver as based for this pcb project. I have designed similar project before, So I know how to deal with it. we just need to control the brighness using either PWM or analog input. I think it will be more stable rather than designing from scratch, it's already isolated too. Let's get in touch via messenger to start this project. let me help you finish this projects. Best Regards, Rijal

hello i am a computer engineer,i have masters in computer engineering,i have experience for more than 7 years in arduino and electronics what is the wattage of ur leds?

Hi. I work as Hardware Engineer in a company that develop IOT projects. My responsibilities in the enterprise are: Design the electronic circuits (analog, digital, control and power); Develop the code for the MCU and embedded systems using software like MPLAB X IDE, Arduino IDE and Python; Test and simulate the schematic of the circuit through simulation software (Proteus and MATLAB/Simulink); Calculate the electrical parameters of the components to implement the circuits on a PCB; Design the PCB of the electronic circuits using software like Altium and Eagle; Redesign schematics and PCB layout for old prototype of circuits with the idea of update the embedded system with new technologies. I have made projects relationated with the home automation using the internet of things using Wi-Fi and Bluetooth modules (ESP8266 and ESP32) and TCP/IP protocol mostly, Also, the implementation of PIC12F, PIC16F, PIC18F, PIC24F and PIC32F, to make create sub circuits to measure data from sensors, creating small devices inside if the embedded system, like the design of a digital wattmeter with I2C communication with the master (ESP12F) using the PIC16F877A, Current and Voltage transformers. All of these projects are posted on my profile. Hope that I have fulfilled your expectations and can be a good candidate to work for your project. Hope we can discuss soon the details for this project. Thanks, and Regards!!!

Hello Dear Employer I am now on a project just like as your need/ Please send me a message so that I can send you my work demo.

I'm new in freelancer but I'm electrical engineer and researcher in university laboratory and I have experience in electronics ( MCu programming, PCB layout ....) let's chat and start a professional work

hi are you need the adjustable driver for up and down the light power or only to turn on light and what is the volt for this led and how much number for the led and how much the the current

I m power electronics engineer having a 3.5 years of experience in power converter design . I have design many led drivers from 5mA to 150mA. i have already design the circuit inducing component selection transformer design plus PCB design. give me your design specifications and I will provide you a detail schematic

Experience of 10+ in PCB design

hi friend, I am an electrical and electronics engineer with 7 years of experience in circuit and PCB design. I can fulfill your requirements with in the budget since your voltage and current requirement doesn't exceed the budget.

i am good ckt designer. i am able to design compact ckt in less time according to your demand. i already worked on too-many ckt designer with different company .

I experience in layout and flyback power supplies and can contribute to your project with a good design. thanks!
