...Interactive buttons are arranged in a circle equidistant from each other with an LCD screen in the center containing the cues unique to each trial. I'm using a Raspberry Pi 3 microcontroller and need a program to release rewards via a servo motor, signal the speaker to emit a chime with correct responses, and randomly generate the appropriate cues/responses

I have an Android app with webview and alarm manager. Alarm manager works as a message checker - every 3 minutes it sends a request to the specified URL. If there are new messages, they appear as push messages. Message cheker should start automatically after phone reboot. It works fine in most of mobile devices but: 1) ZTE phone checks messages every
We have a small prototype circuit (~30 components) based on the ATtiny85 designed in KiCAD and prototyped using a Digispark. Major functionality is incoming power conversion (75v -> 5v), incoming voltage measurement, and current dump into a resistor network controlled by the ATtiny. Project scope is development of a BOM of SMD components based on the
I need someone who can help me build and run a matlab circuit. The ciruit will have an ARRAY OF 5 MICROSTRIP PATCH ANTENNAS, connected to a rectifying Villard/Cockcroft-Walton circuit. I will need us to go through this today. Best Regards,

PIR SENSOR CIRCUIT PIR Sensor PIR sensor is used here to detect the Human body movement, whenever there is any body movement the voltage at output pin changes. Basically it detects the Change in Heat, and produce output whenever such detection occurs. You can learn more about PIR sensor here, there are some useful features in PIR sensor like how to
...man that need to be freed from being locked inside a room in which it has several wires and the user must do minimum cut on those wires to free the man without triggering the alarm. please check the attached files so you can understand what the problem is about and how to solve it. I think 24 dollars for such a project is enough to be paid for and I can

Hi Sergey K., I have a IOT circuit that contains a relay, non-isolated switching power supply, energy monitor and MCU. I need someone to do the followings please: 1- Refine the design 2- Reduce number of components or add any components that is required 3- Send the design for EMC/electrical safety certification/testing and do the paper works etc. I
...prestudy done, drag knife based Fabric cutting head was recommended. This system drags a sharp knife on the cutting path tangent to the cutting direction requiring active and continuous knife orientation change. The fabric is held in position with help of a vacuum bed. A marker system to trace the design on fabric prior to cutting is also desired. In line
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 se...
