Hello! I have a device with USB ports for charging. I need my Arduino Pro Mini to detect if one of the ports is using for charging (Charging right now or not). Scheme of the ports in the picture. I hope the decision will be cheap. I need the scheme and the components.

Проект предназначен для поиска дизайнера для постоянной работы (сначала загрузка будет небольшой - около 1 проекта, как в данном задании, в неделю, потом, возможно, больше). Необходимо перевести картинку в вектор, несколько изменив внешний вид рисунков. Сделайте лучшее и красивее на ваш вкус :-) We are looking for a designer for permanent work (at first the charging will be small - about 1 project a week, as in this assignment, then, perhaps, more). It is necessary to make the raster to vector, slightly changing the appearance of the drawings. Make the best and more beautiful for your taste :-)

Требуется н...management program. It is necessary to control 3-5 incandescent lamp. Pressing the corresponding button lamp should turn on. At random intervals from 0 to 1 minute, the lamp should flash a random number of times with random intensity and speed, after which the brightness of the lamp should be established on a random level. Pressing the same button (the button can be replaced with a toggle switch / circuit breaker) must turn off the lamp. It should be possible to include a single lamp, or all three simultaneously. Decoupling from the high-voltage network engineer will be made separately. We just need to have the control signals to the Arduino controller outputs. Пример / Sample

My model is a motorized hydraulic jack using a motor and wiper motor of 12v and the power to this machine will get from the battery of the car. The link of videos is given below: I'm providing a ppt file from which you will get some information regarding my project.

The aim of this project is to create a virtual setup of an SRAM PUF (Physical Unclonable Function). The setup will consist of a simulation of an SRAM-based circuit that can be used to generate unique and random cryptographic keys for authentication purposes.

I would like a design, preferably in EasyEDA that can be created and assembled by JL PCB (or somewhere similar if you know of a better solution). The board will need to include pin headers to plug in an esp32 dev board as well as a raspberry pi zero. The i/o on these boards are then used to control a relay and a few other simple devices that use the i/o. There are a few incoming connections like a usb serial connection, power, and wires that the relay shorts. I will need some advice on the best/cheapest way to handle some of the functionality, like whether we should just put pin headers to plug in a pre-fabbed unit or build it into the board. Please provide at least a ballpark amount that you charge for these kind of projects and then we can discuss in more detail before settling on a fi...

I'm looking for someone to design an enclosure for my printed circuit board (PCB). I require a fully measured CAD drawing, as I need the enclosure to meet exact specifications. I do not need it to be water-resistant, so no additional waterproofing measures will be necessary. The material I need the enclosure to be made of is plastic. If you have experience in creating 3D designs for plastic enclosures for PCBs, please submit your proposal and let me know how you can help. Please no fake quotes.

Hi, I'm looking for an PCB expert that can design the circuit, the gerber files for pcb printing and create a list of needed component to assembly the pcb.

we have a project to build a device which is connected to vehicle battery and its CAN line. this device has a USB female port which would be connected to a mobile using a normal mobile charger cable. The motive would be to charge the mobile phone and communicate with the device on usb. we have already built a unit but we are not able to both charging and communicating at the same time. charging happens when a normal mobile charging cable is used. communication happens only when an external small otg adapter is used along with the charging cable. we want a fast charging device that would also communicate with the phone only with the mobile charging cable.

We built a buffer board using CD4011 ic to split the driver signal into 6 channels which is 3 for the high side and 3 for the low side. Then we built a transistor board and an optocoupler board that is used to feed the signal to the driver board which was designed using IR2110 ICs. This driver board is what should drive the emulator board (the mosfets) which receives the battery input and then drives the transformer. Currently the mosfets keeps getting hot a...

AMP BRIDGE . Its Home Flex 50-amp smart charger is similar in operation to its public chargers so there is no learning curve. It can be hardwired into a 240-volt circuit (typically the home’s drier circuit) or an existing 240-volt outlet. The 23-foot cable allows for more installation locations in your garage and the whole charging unit has a sleek design Sometimes you don’t need smart-charging capabilities. Instead, you might need a durable outdoor charger that can withstand tough weather conditions. AMPUSHER is ideal for home EV charging, as well as electric lawn/farm equipment, which is a growing market. There’s no app to this one, just a rugged 40-amp charger. This unit can be hardwired or plugged into an existing 240-volt outlet and...

I need a motor and gear set for a device that quickly grips and holds an object. See attached CAD of gripper mechanism.
