Electrical engineering is a branch of engineering that involves the study of electricity, electromagnetism and electronics. An electrical engineer knows how to deal with a host of electrical appliances and devices. To ensure that your electrical device is compliant with the set standards, you need to hire a professional electrical engineer. For this, all you have to do is hire a professional electrical engineer. Once you have an experienced electrical engineer onboard you can hope to add a fillip to your business.Od 74152 ocen, stranke ocenjujejo našega Electrical Engineers 4.82 od 5 zvezdic.
Arduino stepper project I need a capacitive touch (like TTP223) which, if hold down for 5 seconds, turns the whole device on and off. i also need a screen (EDO E1473AC63) with three buttons designed, a bar to indicate the battery level and a bar to indicate the stepper motor effort. if the buttons are kept pressed, they activate the stepper motor. the engine starts only if the button on the display remains pressed. if the button is released, the motor stops. There are three because they have different acceleration and maximum speed. acceleration and maximum speed must be set from a smartphone that communicates via bluetooth with device. I also need a function that if I press three fast touches on the display with two fingers, the motor moves to the zero position (the zero position...

We are paying for written application notes based on our programable mixed-signal ICs & integrated power switches. These parts are very versatile so there are many applications that they can be designed for. The application note should be a 1000-3500 word technical white paper describing an application and how it uses the part (ICs or integrated power switches). The writer will be responsible for generating the content as well as writing the app note.

I want plans to build a food vending machine with freezer (-20c) part that can stock 500 items, has mechanism to take out an item, put it in an oven and, once warm, deliver it through an opening (like vending machines). Interested? Contact me for more details. Sorry all honest engineers, I checked reviews of freelancer.com and it's not good. I will close my account and launch the project on another like fiverr or toptal
Code for arduino needed. I want to the machine to run until ice is ready to drop into container in short. What I want to do is use a sensor (it's just 2 copper pieces like screws) to connect to each other as soon as the ice is thick enough that completes connection to initiate the drop cycle. (contact with ice on sensor should be for 20 seconds incase false reading) After that it should activate a relay that controls the ice drop until it's finished. After ice dropped the sensor disconnects and relay switches off.

Honestly I was unsure what to actually input further.

We are looking for a senior firmware developer who can consult us on various aspects of development for BLE application using the NRF52 and other Nordic Semiconductor System-on-Chips (SoCs). The first job on hand (this request) is low power optimization of an existing application, this would require good co-ordination with our developers (remote teams), firmware review, bug fixes, and adaptations to reach the desired power consumption levels. Expert knowledge of low-power schematic design, firmware development and integration is a must. We are looking for individuals and NOT companies (any time zone is okay, but we prefer Central Europe).

I have created the following project below. However it is too basic for a final year project, I need a larger scope for this project. Please provide any help . The alarm system is to be applied on 3 windows and a door. Each window and the door has a sensor (switch) such that when it is opened, it will give logic level 1. There is an on/off switch for the alarm which will be represented by the variable Y . If we want to turn on the alarm, the switch will give logic level 1. Otherwise, it will give logic level 0. The alarm system will be using a 7 segment display. When the system is active, the display will show character A. When it is closed , the display will show character 0. The switches below will be connected to each sensor output. • sw – window 0 • sw – ...
