I need an arduino controller programmed to do the following. There will be 8 independent inputs with magnetic contacts at the end of each. When all the magnetic contacts are closed, I need the controller to send a signal to a mag lock to open a door. The maglock shall then remain open until a master reset button is pressed, even if one of the 8 inputs gets opened. Everything should be powered from 12vdc. If you have any further questions please dont hesitate to contact me...I am new to arduino so Im sure I will have plenty of questions myself.

Create optimised code for Arduino 2560mega to control a variable output cooler and fans using a PID loop with three temperature sensors. will need to drive 16x4 display (probably 88470) and use up/down left/right enter/exit keys to set values etc.

We need an expert that can revamp and correct a library that was written for the Skywire 2G CDMA 1xRTT (http://nimbelink.com/2g-cdma-1xrtt/) to be used with an Arduino. The deadline for the project is 9/9/2015. We currently have a library that was written by another programmer but never revamped. Unfortunately, he is no longer available so we need someone to take over the project and finish it off. The currently library works flawlessly but it needs to be revamped because the library is very bloated and uses a large chunk of memory. Thanks.

We are making a product with a BLUNO as a master. We need it to connect and communicate with an external product, with BLE services (documentation provided, and hardware paid by us). The goal is to develop a library allowing us to : - discover the device - connect to the device - read notification from BLE device - write to BLE device - read from BLE device

Background: As you likely already know, to control amount of power a flash puts out, flash duration (and hence light output) is reduced by a thyistor control that quenches the full power flash early for light output less then 100%. Requirement: Need a circuit to be designed (along with PCB design) which will register the flash quench duration (generated by the center pin on a DSLR flash connector) and converts it into a power output that can drive a bank of high speed LEDs. Either using purely discrete components or using an arduino (your choice whatever you think is simplest). If a micro-controller is used, I will need the code as well. The output of the circuit should be able to drive and control intensity (either PWM or otherwise depending on the LED driver driver used) of a bank of LEDs.

I need someone to program an Arduino touch sensor pad. The main electronic components will be an Arduino MCU, touch sensors and LED lights. I have a few options on how I can make it, but I have a limited background in electronics so I need help first to determine which method would be the most effective, especially which type of sensors would work best for the field conditions. Once we decide on the physical layout, I need you to program the Arduino to pick up the sensor signals to light up the LEDs.

i am looking of some onto convert some arduino code to c++ with chinos/rt based OS from arduino code, i also need you to do the opposite. adruino uses atmega chip the chinos/rt uses stm32f100 and the last thing is i need to do help add support for a device to one of the codes. the hardware is a wii nunchuck replacement pcbs made specifically for controlling an electric speed controller.it has been made because current wireless wii nunchucks are unstable and have bad wireless connectivity. the wiiceiver is a pcbs that was deigned to plug in a wireless nunchuck receiver in and output pwm signal for and electric speed controller and servo. i need to make the wiiceiver read the axis and button presses from my nunchuck pcb. but i want my nunchuck pcbs to stay comparable with arduino so i was going to allow support for stm32f103 and them release arduino code to the public. ardunio code: https://github.com/jaustindavid/wiiceiver chibios/rt code: https://github.com/vedderb/nunchuk_mod
