I need to create a simple circuit diagram including specific components that allow me to detect a light or infrared, and get a 5v signal in an Arduino Uno when the light is seen. I have a 5v laser for Arduino and the sensor may get only a 1% or less of the intensity of the light. don't think if there is light around, the sensor and the laser will be inside a dark space. Could be awesome if you can use LTspice XVII to make the circuit.

We need C#/Unity expert that would copy the native iOS/Android SDK for nRF52 Sensor and make Unity Plugin for it. We need to read accelerometer data and display it on the screen.

We would like to create a video with 3D animation showing how our liquid metal circuits can replace a rigid circuit board with a super stretchy material that can be embedded into a thin glove, shirt, elbow sleeve, etc. We'd like to show an exploded view of circuit/sensor with the typical "engineering diagram" aesthetic (like in the attachment) pointing out key components and capabilities. Then we would like to animate it “going into” a garment and convey that there is useful data now streaming out of the clothing. Perhaps after the circuit is embedded, we zoom out and see that this garment was being worn by a person and they are performing an action and it is emphasized that the material is still extremely thin and pliable. I have attached some imagery. ...

Hi, I need someone to make this simple VI for me. I would like to measure the speed of a rotating shaft inside a transmission gearbox. There's 3 shafts in total, each having a hall effect sensor mounted to them. I would like to have the RPM of the shaft displayed on gauges at a rate of 10 Hz minimum (meaning 10 RPM readings per second) in order to have a high speed reading of the speeds. The data must also be logged with their time stamps. Additional info: The speed sensor outputs a voltage (pulse) with each passing gear tooth so you can simulate a high/low digital signal to as an input from the sensor. I have already attempted to write this VI but it is currently unreliable because it fluctuates. The DAQ device I am using is the USB 6002 from NI and I want...

We need a sensor added to a machine that resets a timer each time a knife cuts. The timer needs to be adjustable. Once the timer reaches the limit, the machine needs to shut off. It should be a fairly simple wiring job. This is a one-time job, but if we like your work, we will keep your name on hand for other similar jobs.

We have many simple modules to design like temperature sensor or LED drivers. For each module, you must select the key components and produce schematics and layout in Altium. You must also provide a basic Arduino firmware for basic interactions with the module. The jobs will be awarded on a per module basis but ideally the same person would end up making most of them. You must be experienced with Arduino and Altium.

...sound commentary would give the feeling of a game such as “New High Score”, “You’re Slowing Down”, “Congratulations!” Multiple pressure sensors can be used for a single target to detect accuracy. By hitting the center sensor for example would give a 100% accuracy hit but by hitting a surrounding sensor may indicate a 75% accuracy. A similar commercial product used for reaction training can be seen here from to give you an idea of what it could look and feel like. It’s possible to turn an MMA/boxing punch bag into a game by strategically placing multiple sensor/pressure pads aligned inside of the bag to use as hit targets. Sensors would be placed around the bag in areas representing targets such as the head and body...

Need programming done in codesys3.5 Scripted Text Need hydraulic motor 1 to be controlled by 2 speed variables. a Wheel sensor tells us ground speed which has to be matched by hose speed overlaid with a control feature for min/ max system pressure A absolute rotation sensor on a rotating drum tells us speed distance and direction . We use this sensor to set up a ratio to operate another hydraulic motor that drives an operation in a by directional manner that is monitored with another absolute encoder. This operation will also be speed up or slowed down based on another encoder that senses the proximity of the material. if to close it speeds up and if to far away slows down based on a table graph
