I'm looking for a programmer to help me write code for an arduino run circuit. When a button is pushed, two things happen; 1. one led lights, then dimm's down within a 1/4 of a second. 2. the next led lights, then dimm's down within a 1/4 of a second. I will be using super bright led's, like the ones shown here;   [obscured]  /products/531 ill be looking to make this gimmick pretty small, but enough current to supply the led's. To further understand my requirements I would be happy to discuss through Skype or google hangout. This job is also a trial employment; as further electronic products will be needed in the future. If there's any more information you require please don't hesitate to ask.

I am looking for a PCB layout (ie Eagle CAD files) for an Arduino Mega shield featuring an RS232 and RS422 (full duplex) port using the TTL level UARTS supplied on the Mega. The shield should provide a terminal block access (3 connectors for the RS232) and (4 for the RS422) which should be positioned on the power supply/USB end of the Mega. A bonus would be to have LEDs to signal communication activity on ports.

I need some help with my code in Arduino. IŽd like to make a distance measurement and this distance I want to see on a LCD. Thats not that difficult. But the measurement should be displayed via Bluetooth in cm or mm on the LCD (1 - 2m away). Hardware should look like this: HC-SR04 -> Arduino-> "Bluetooth" (such as HC-05) ->.............-> "Bluetooth" (such as HC-05) -> Arduino (if here has to be another one) -> LCD Please have a look at my changes for this Project: 1. I found a cheaper way to send the distance to the LCD. Because there is only a one way connection I though it will be ok to take a Transmitter-Receiver pair (433Mhz RF). See Attachment 2. There schould be another sensor with an Arduino. So I have one Arduino who measures on the right side and one who measures on the left side. Both should send the measurement to the lcd. The Arduino on the left and on the right side are not connected. 3. The You should see the lowest measurement on...

We have hundreds of industrial machines for manufacturing processes. Most of these machines have simple control panels and are not connected to the corporate network in any way. We would like to connect some of these machines to the corporate network and log the status of the machines to a central database. This way we can perform analysis on the machines. The first machine that we would like to attempt this for is a knitting machine. After opening the front panel of the machine, we see Molex styled connectors used to connect the front panel to the main logic boards of the machine. We have also found documentation that clearly describes the pin outs. We would like to tap into these connections and connect them to a Particle (  [obscured]  /prototype) Core or Photon. These prototyping boards are Arduino-like, but also come with a strong management platform. Much of the information that we want to capture is simple on/off status information. For example, is the door of the mac...

The objective of my project is to use a wireless physical device that is moved in 3D space in order to play computer games. I'm interested in embedding an IMUDunio (by Femtoduino   [obscured]  /) in the physical devices and assigning different gestures so when I move the device, in a certain way, it will be interpreted as a keystroke or a mouse move. This will enable me to play a computer game with the device and replace certain mouse movements and keyboard keys with the device. The IMUDuino should transmit all the data from the sensors to the computer, the computer should do the processing for recognizing the gestures. An example for this is Playing a game like Super Mario Brothers where: 1. Leaning the device forward, will make the character move forward (like pressing the right arrow). 2. Leaning the device backwards, will make the character move forward (like pressing the left arrow). 3. Moving the device up and then back down (like a jump), will make the character jump. 4. etc...

Write code for Arduino to read a light sensor, display values & parameters on an OLED display and drive two digital outputs based on desired operation. Because I am new to this approach on elance, this work will be divided into very small sections so I don't break the bank. The first part is described in the files attached. 1. The Arduino constantly watches the switch input and the light sensor input and displays 6 labels on the display with their respective values. CLV - 0 to 1023 showing current light level DS - "O" or "C" showing where the door position should be LL - showing the saved light level that is in memory for a Low Light condition HL - showing the saved light level that is in memory for a High Light condition SW - showing a "0" or "1" showing the current switch status TTSC - showing the value of the countdown timer in seconds. 2. When the switch has been pushed once, the Arduino flashes the LL label and updates the LL value in...

In a nutshell, here is what the electronics need to do: 1) The camera shutter is opened through a push lever. It actuates a switch - signaling the processor to start measuring light 2) Light measurement gets converted into a usable value and exposure is calculated based on other parameters (focal length, pinhole diameter, reciprocity value, EV compensation, and constant) 3) Light measurement is taken every second to account for lighting condition changes - Pinhole photography exposures tend to be very long 4) Once proper exposure is reached - circuit actuates a servo to release the shutter lever which closes the shutter through mechanical spring energy. The servo just needs to tal the lever to release the mechanism. The APP would have a databese of films, constants, etc. and provide camera the selected data to the circuit (pinhole diameter, dilm, EV, focal length). The circuit in the camera will keep this data and use it to calculate exposure. Current design has a screen built in and...

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...

#################################################################### ### May 22 UPDATE: requirements scaled back re. masks speed and number of mood lights ### I need a small windows application to show only pixels of a particular brightness value in sequence (for either AVI or WMV or MP4 video, and a webcam feed), while communicating with an Arduino to turn on 5 separate mood lights (corresponding to each brightness level). Details: 1. Application displays only pixels of a particular luminosity range at a time (like a mask on black background), in sequence. Eg. displays only pixels in the frame that have a 0-20% luminosity, then 21-40% luminosity, etc. (total of 5 ranges/masks). Then moves on to next video frame. The number of masks displayed per second should be the same as the monitor refresh rate variable - that can be changed. For example, with a 60hz monitor, each mask shows every 1/60 sec, or 16.6ms. At 140hz, it's 1/140 = 0.007ms. 2. Each time a mask above is displayed (5...

We need a device consisting of a microcontroller (such as Arduino) that will constantly monitor a voltage in the range of 0 to 3.3 V. When a voltage change is noticed, the microcontroller will wait until the voltage has stabilized to < 1% variation for at least 250 ms, and then send an RS-232 command at a baud rate of 115200 bit/sec. The command is in the form "P=Y.YYY" where Y.YYY is a number format with a value that ranges from 0.000 at an input voltage of 0V to 1.000 at an input voltage of 3.3 V, with a linear interpolation in between. The form factor is less than 7x7x2 cm. Input power is 24V provided through a BNC connector. It is preferable to use the RS-232D standard, with an RJ45 jack. The unit must start up and start functioning automatically when 24V power is applied. It would be good if we have the ability to reprogram the device simply on site in case we need to adjust some parameters. Supplier is responsible for procuring and assembling all parts, and...
