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.

In order to validate the functionality of all components of my circuit, I am looking for a circuit and PCB designer which can do the circuit refine, design and prepare the PCB boards. To give you a general overview of the circuit: it is basically the whole supply of the circuit which consist of a solar-cell charger and a 9V battery which must provide us a 3.3V output for the micro-controller, a 5 V and 100mA to drive a solenoid and a 5V and 500 mA for a USB charger. I have used 3 ICs made by Linear Technology, which I can provide you with all their datasheets and information if it is needed. Regards, Sanaz Haddadian

Update: After a long discussion with my insurance agent, I've removed the design insurance requirement. I am looking for a electronics design partner to create two printed circuit boards for a robotic lawnmower. I am price conscious and interested to learn about any price trade-offs that are available. I believe I want two boards as follows: The base station should contain a PCB that is AC powered using an external transformer. It should have basic location capabilities, an RF transmitter, a modulated infrared light, and provide power to charge the robot unit. The robot should contain a PCB that is battery powered. It should contain a micro-controller, multiple motor drivers, battery management, GPS capabilities, an RF transceiver, and infrared sensors, a small LCD touch screen, sound generation, and several sensors including one or more cameras. These boards should be in compliance with relevant US and EU regulations and standards. You should produce basic software for the sy...

We are in need of an individual or company skilled in Microcontroller Programming using a CCS compiler. The micro controller we are using is a Microchip PIC18F67J60-I/PT. Familiarity with FPGA programming is a plus, but not necessary. The PIC will communicate with a Spartan-6 FPGA chip and Microchip RN-171 WiFly module. We have source code for the existing firmware, however we need updates and debugging to the existing codebase. Time sensitive requirements with possibility for a long term relationship.

Hi, I need a circuit board designed and code written for a device that will transmit a weight over GSM to remote servers. The signal coming in will be that of a load cell. I would like the inputs from the load cells to be intrinsically isolated if possible as well. Once the signal is received by the Micro controller, it needs to be sent by GSM. That signal will be sent to a remote server and a web application will use the data to provide customer specific information. The unit will be able to take from 1-10 inputs from the load cells for now, depending on the application. Some Digital outputs from the controller will also be transmitted for alarms. The unit will need to be battery powered, with battery level indication also transmitted. I was thinking that readings from the load cell could be stored up and every couple of minutes sent to server to save on battery life. The project is in South Africa. So, I will need controller, modem etc. to be freely available here. I would prefer...

I need to code an Arduino micro-controller to rotate different servomotors, depending on which pushbutton is pressed. Basically I will be making an automatic drinkmixer or bartender. There will be an rfid card and tag to activate the machine, and a series of pushbuttons to control which servo to rotate so that the fluids can be dispensed. This is a project for my programming class, but I dont know how to code Arduinos. I also would like a sketch of the circuit please Please open the attached file for more details Algorithm is attached.

[Description updated at 4:33pm PST, 3/16/15] Thanks everyone for your proposals. Last update before I pick a proposal: I should have stated earlier that output precision is important. I want to hear your plan for current sensing and how to get good mA output precision. I've read that combining high side with low side sensing is good. Below I've only updated "OUTPUT PRECISSION". Thanks very much! GENERAL DESCRIPTION: Needed is a prototype device (along with any parts lists, board diagrams, schematics, etc) which regulates output current from a battery supply, over a variable resistance between 30K ohm and 200K ohm, at or below 2mA. Output voltage will be controlled by the device to maintain the output current at 2mA. The device will feature a basic LCD character screen and button inputs. See attached mock for the basic layout and working of the controls. OUTPUT PRECISSION: Would like to get precision of 0.1mA or better, and know that 2mA will not be exceeded (safety measur...
