AC lamp dimmer using 16f628a microcontroller

Hi, I can design the AC lamp dimmer using PIC controller, I have 14 year experience in electronics, micro-controllers and system designing, therefore am quite confident that I can take your project. Following shall be the expected milestones: 1. Specification requirement document. 2. Schematics using Altium 3. Simulation of code and electronics (Where ever possible) 4. Software delivery. About my self , you can review my profile and my clients comments. Best Regards.

Hi I have experience if pic 16f series. Let me know more of your hardware and requirements to give my best solution. Check my profile for my experience in embedded system. Looking forward to hear from you.

Hello, So the problem is what you use to control the light. I don't know if you use a relay or a triac I have to see your schematic in order to give you more helpful information. I have designed system that work on AC voltage before and MCUs that control the AC voltage You can have a look over my portfolio and reviews.

hello i made the same circuit using arduino, the main problem was zero crossing detection , you can solve this using H11AA1, the dimming rang from 0 to 100%. we can desgin it using potentiometer, or push buttons as the video shown.

Hi, I'm an electronics engineer with more than 6 years of experience in designing and developing various digital and embedded systems... Currently I help engineering students to complete their academic projects. Also conduct seminars and workshops on Microcontrollers and Robotics... So I have experienced with a lot of Microcontrollers such as PIC, AVR, ARM, Arduino etc. I'm also experience with a lot of sensors and sensor modules.... I'm very proficient with EAGLE too... Please check my completed projects and reviews given by other employers...:-) And I have done similar project for an AC FAN speed control..:-) I really would like to know more about your project, kindly let me know if you are interested...:-) Thank You

hi, i am an electrical engineer and i have an experience in designing analog electronics and microcontroller based embedded systems. i can design your Dimmer using PIC16f628a with efficient output response. recently i have developed a dimmer using Pic18f1220 which is controlling the firing angle of SCR (Triac) to regulate the AC voltages and showing the resultant output voltages on LCD. please contact me if you have any question or need further details regarding to the project. thanks, Rizwan

i can help you with this your circuit is flickering because you are not having perfect zero crossing . i have done more than 20 projects in which i have to perform dimming or speed controlling by controlling firing angle of ac.

I did an almost same project few years ago with PIC16F88 and for powerfull circuit and worked good, so i think this is can be done too with PIC16F628.

Hello, I am doing a similar kind of project like this right now (actually it is a small part of my ongoing project :p ). If you award me the project, i need to clarify some things first, 1. What type of Bulb / Lamp are you going to drive ??? Because the bulb in the video you linked with the project is an Incandescent Bulb. 2. What are the required things when the project is completed, i meant a) Working Video b) Working Video + Schematic c) Working Video + Schematic + Hardware shipped to your Address It's all i need to know till now, if you feel that you will award me the project, feel free to knock me for more discussion regarding the project. Thank you. Best Regards A N M Muntasir Hossain Tonmoy Skype : tony67_bd

hi I am an electrical engineer. I have this circuit and its simulation on proteus. please contact me if you are interested. thanks Wajih.

I've made a few dimmer with a PIC microcontroller in the past, pretty sure I can make it work very reliably.

hi, what duty ratio and frequency are you using ? what component are u using for the dimming function ??? what kind of ac lamp is it ???

Hi! I am an experienced electric engineer and PCB designer with advanced knowledge about product design and development. I have a huge experience in Altium Designer and I use it more over eight years. I have designed many building automation device such as motor controller, controlled switch, dimmer and gateways. In my works I have used various communications technologies like RS485/232/422, IP, Z-Wave. All of my design complied with the strict European EMC requirements. Please provide further details of the project if my offer is interesting for you. Kind regards, Zoltan

You have mentioned during dimming. Please specify the load you are using. it is CFL or simple bulb load or led load. I have decade long experince in design and development. i can do ti for you in pic16f628.

Hello, a few years ago I was doing a similar project. With the same controller is done only to use the remote control instead of buttons. I am interested in your project.
