I am looking for instructions on designing a LED wired circuit. I currently have most of the parts and need instructions on how to connect them and make them work. I want to connect some RGB LED to the micro controller to be able to control the color. I am not sure what order or what resistors to use and where.

We are using the Synapse Wireless RF200PD1 in our product. We have an order to supply our product to Japan. We need someone fully familiar with the requirements of obtaining a modular certification of the radio module in Japan, who can shepherd us through the complete process and, if necessary, help prepare the documentation. Most tasks such as preparing the module for certification testing, drawings, etc. we can do, but we need leadership to take the process from beginning to end including selecting the test laboratory, the certification house, etc. Final deliverable is the Japanese certification letter. Successful bidder will demonstrate that a similar certification has been accepted. Japanese consultants or Japanese speaking specialists preferred but not required.

We need help designing a very simple circuit, that will fit our specifications. We are trying to use the attached LED, with the attached LED driver (or an equivalent), but we don't know how to design an appropriate circuit for our specs. We want the LED to run at 18.2V and 1.2Amps. We don't need anything fancy, no PWM functionality. We just need to turn the LED on and off very quickly via a +/- 5V signal. Please see the "Shopping List" below for further requirements and specs. SHOPPING LIST: Input Power 24v dc-27v dc Battery 150AH Led Requirements 1. Build a linear array of 120 light that will be powered using a 24vdc 150 amp battery. 2. The lights will be mounted on a heat sink that will cool the lights to temperatures well below the required operating temperatures. 3. Regulate input to each led to 18.3v dc and limit amperage to 1.2 amps 4. Ability to turn light on and off 10,000 times per second for 14 micro seconds. 5. Each LED will have a dedicated driver to prevent t...

Our product will monitor soil conditions and perform actions based on the measurements. Using an app (Android, iOS, and web based), users can specify triggers for notifications when the soil is outside of the acceptable range (for example, if the temperature is approaching freezing, or soil pH is getting too high). The app will also access the historical data that will be stored via the web to track growth and associate pictures taken. We would like the device to meet the following requirements: Sensors Temperature:range from -40 to 140, accuracy of 1 Humidity: range from 0 to 100% RH accuracy of 2% Barometric pressure Light intensity: range from full daylight to night using photoresistor or solar panel to detect Soil pH: range of 4.5 to 9.5 pH, accurate down to 0.5 Enclosure Waterproof Weatherproof & UV resistant 3"x3"x2" maximum dimensions (not including any probes that would go into the soil) Replaceable battery (AAA or AA size) Data The device should tra...

You will get a real life netlist of a combinational block (no memory elements). Your task, is using standard Python programming language Generate a new logically equivalent netlist which only uses NAND2 and NOR2 gates, which replace all the different gates that are there already.(refer block32 notepad for verilog code) Requirements: ? Code should be tidy and commented ? The code should work also on other netlists ? make it as generic as possible ? The netlist generated should be a legal verilog netlist including input, output declarations, wires, unique gate names etc. ? Tip: use a text editor that supports highlighted verilog syntax like: sublime text, Notepad++, Nedit or emacs ? Assume the drive strength to be X1 in all NOR2 an d NAND2 that you would use ? Code should be easily extended to new types of gates upon request ? i.e. when a new netlist comes with new gate types inside ? the change process should be easy

I need a program for an Arduino board so that it can generate 2 types of PWM. 1. Space Vector PWM - SVPWM 2. Hysteresis band current control PWM The user must be able to select the type of PWM that he wants and the frequency (1-200 Hz). The frequency will not be changed with a potensiometer because of the noise but from the serial monitor. The system is intented to work with a SINGLE-phase inverter. The Arduino board that will be selected will be arduino uno. The final deliverable should be the arduino code files with extensive comment documentation.

We require an engineer to consult us on the plausibility of our idea and solutions to a few engineering problems we have for said idea. We need an engineer who is experienced with current bluetooth/wireless technology, small electronic measuring parts, and circuit/programming knowledge. We aren't necessarily looking for a full-up design files, but we would like to know if what we are trying to do is plausible and what technologies we would need to accomplish it.

ARDUINO-BASED CUTDOWN DEVICE FOR HIGH ALTITUDE BALLOON This project would involve designing, programming, and fabricating a finished prototype, possibly using a small single-purpose Arduino processor (i.e. Micro or Nano, or something similar) to serve as a cutdown device for a high altitude balloon. Requirements: - The device needs to be as small, lightweight, and durable as possible. - The device needs to operate using an Energizer Advanced Lithium 9-volt battery as its power source. Operation: Basically, the device would be a simple timer. - Turn on the device and a small red LED begins to flash, letting the user know that the device is active. - Turning on the device starts a 60-minute countdown. At the end of the 60-minute period, the device would activate a reed relay to allow current from the 9-volt battery to flow to a user-supplied piece of nichrome wire that would heat-up and sever a small piece of braided mason lin...

Job description: seeking a firmware or software developer who has experience with the ESP8266 WiFi module, and who will be responsible for developing a web-enabled acceleration sensor. Project: a WiFi-connected acceleration sensor that streams data to a connected web browser. In this device, the acceleration sensor (ADXL345) is connected by a 3-wire SPI interface to a WiFi module (ESP8266). This WiFi module contains an integrated microcontroller that must be configured to handle html requests, serve resulting data into formatted web pages back to the connected browser and control the sensor based on internal state, logic and html requests. The firmware will be released under the MIT license on our GitHub account or yours (your choice). We will ship hardware to you for both devices and links for all datasheets including the English ESP8266 datasheets, you will need to hook up data/power wires, what is additionally required from you is your own computer for development and a micro-USB ...
