Hi I am controlling 4 servo motors with an IR remote control. Two servo motors is used for x axis (left and right) and two for Y axis up and down. Need help to save position of the servo motor. So when you shut down power to Arduino and start it up again the motors will stay i same position. I need also help to save position of x and y to the push buttons 1 to 4. So is possible to adjust position you want and hold down push button 1 for 5 sec and it will save that position so next time you can just push button 1 and the servo motors will move to that position. Best Regards Douglas
Looking for someone to write an IEEE paper based on a speech recogntion project completed. Please be an Electrical and/or Software Engineering student so that you can understand the terminology. The project has been completed and will need someone to write a detailed paper explaining the project. I will provide all necessary material and links.
Hi folks, I need a person who knows electronics and programming, to implement a simple USB device. - The computer will send 20-bits of binary information to the device, via USB - The USB device will do some simple operations. - The USB will send back 10-bits of information, also via USB - The computer will store the 10-bits, and repeat the loop with another 20-bits string. You are welcome to send a bid! Please send detailed information about how you will approach the problem (e.g., components, libraries, etc). I need to know that you know what you are doing. Please see the schematics, and contact me if you have questions. Thanks, and I look forward to work with you!

I need 51 metered boxes at a single location. 50 of them will only power 1 20 amp dual breaker, with 1 circuit and only 1 outlet being powered. The last meter will have 2 or 3 circuits. I'm 100% confident in everything I need from the 20 amp breaker to outlet, just looking for a diagram and possible material list for the rest (I've got one in mind, but still being told I need a LOT more). I'm being told there's at least $20,000 worth of "outside" cost before even getting inside. I believe this is extremely high considering my understanding of what actually needs to be done, as opposed to what the electrician wants to do. I would like to buy all the materials that I need before asking an electrician to give me a "estimate". With the design, I'll have the ability to direct the electrician to do what I want, and walk away from what I'm being sold.
I will send information regarding kVA of equipment and I will need you to estimate 4 transformers size and fuse sizes.
Saya puny project.. saya puny program PSIM (sudah ada rangkaian lengkap simulasi) untuk mensimulasikan sistem kelistrikan. sistem saya ketika dibaca pada sinyal tegangan (sinusoidal) pada detik tertentu terjadi ketidak normalan sinyal. dalam hal ini pada detik 0,2 sesuai yang saya rencanakan. terdapat 39 kondisi sinyal berbeda (sebelum detik 0,2 hasil keluaran/nilai dari semua sinyal sinusoidal hampir sama untuk keseluruhan kondisi beban sedangkan setelah detik 0,2 sinyalnya berbeda. setelah detik 0,2 merupakan ketidak normalan sistem). pada dua kondisi yang saya jelaskan diatas. saya ingin membuat artificial neural network yang dapat mendeteksi kondisi tersebut. dengan cara mensimulasikan masing-masing kondisi dan ANN mendeteksi ketidak normalan terjadi pada detik keberapa dari sistem. sistem pembacaan yang diharapkan pada ANN adalah pembacaan persiklus. Untuk aplikasi pembacaan sudah saya buatkan (uji&test berhasil) menggunakan matlab. hanya saya harus melakukan sistem secara manual untuk mendeteksi. apa saya bisa dibantu supaya ANN dapat mengamati perubahan sinyal pada titik pengukuran secara otomatis di aplikasi Psim? waktu pengerjaan 3 hari..
We use oki c711 laser printer... this is a comum laser printer which is based on sheets feed, like A4, Letter, etc page sizes. We need to modificate firmware of printer that when we sent for example 10 copies of document to print, the printer doens´t ask for load next page sheet, and just continue to print on continuos roll. If you have any doubts, I would appreciate to explain better.
I am working with modules ESP8266-01 and SIM808. Both can send HTTP post with sucessfull, but is required HTTPS. I need a freelancer that already have sucessfull on deploying Arduino with HTTPS (ESP8266-01 and SIM808). No fingerprint certificated method will be accepted, because the certificates are exchanged each 1 year.
Description is incomplete, please refer to the PDF file provided for a more detailed understanding. PLEASE Show all work, steps, and explanations [login to view URL] are given a 4-bit SAR ADC as shown. The reference voltage is 3.3 V, the input voltage is 2.427 V, the comparator has no offset voltage, and all capacitors are perfectly matched. Make a table indicating the position of each switch (including the reset switch) and the voltages vx and vout for each step in the conversion process. What is the complete ADC output word? 2. In this problem we will look at a 2-bit MDAC used as the first stage of a 14-bit pipeline ADC shown below. As will hopefully be clear by the end of this problem, the first stage of a pipeline ADC is typically the most critical. For each clock cycle, half of the clock cycle is spent sampling, and the other half is spent in the conversion and residue amplification process. We will assume that the amount of time for the 2- bit flash to make a decision is negligible. We clock the ADC at 10 MHz sample rate. a. How accurately must the output of the 2-bit first stage settle so that the ADC maintains a 14-bit resolution? How many time-constants do we need to wait to settle with this accuracy? b. What GBW does the opamp need to settle with the accuracy of part a, and the given clock rate of 10 MHz? c. If the opamp has finite gain, this can also limit the accuracy of the settling. What is the minimum opamp gain needed to guarantee the output is capable of settling with the accuracy found in part a?
Engineer needed to design+create student quiz questions (basic knowledge of electricity, assembling objects, mechanical concepts, verbal reasoning, math + some design skills are REQUIRED).
I need a chain or arduino's, maybe more then 100 Arduino's even. I am not sure which protocol I like to use. I think I2C and also RS232 are options. Each Arduino needs a number of digital IO at least 16 or so. Each Arduino must be able to send short messages to the neighboring Arduino. The whole chain must be controlled by a pc.
The purpose of this lab is to design a VGA driver to display 256 different colors on a monitor. Two timing signals are generated in this system, vsync and hsync to synchronize the plotting of vertical and horizontal pixels, respectively. The color data of each pixel is generated using an 8 bit counter whose first 3-bits are for red, next 3-bits are for green and last 2-bits are for blue color data while the synchronization signals are generated. This way, as the counter counts, 256 different color combinations are displayed on the screen one after another. This counter is implemented on the FPGA board
