It's simple app, just need to send and receive messages through cellar network. App need to send sms as well (so either CSD or SMS) Interface of the app doesn't matter, but should work in offline condition. We will use this code for next iteration of our app. We expect executor to join us on next iteration (with separate pay). Deliverables Android app, that can NO Twillio API or other API, that will require to send data to specific number. But you are free to offer your vision of problem solution.

    Hello, I'm interested in building a small controller for my small garden room, that have input, and then based on input data, it deals with output. The following are the main input and output. - Battery level reader - 2 Water Pump for 2 different job work - Water level - small Peristaltic pump - Humidity reader - Temp. Reader. - Open switch (to let fan work and decrease humidity) - Open switch (to let EVAPORATIVE COOLER work) can it be done with Arduino or another microcontroller that work with battery? if yes, then how ,much will this project cost me?

    I need to design a wireless battery charging like one of those show in attached pictures. In 1-2 pictures you see planar antenna for wireless power transmission and cylindrical antenna in the receiver section: this is the first possible solution. Second solution (3-4 picture) is to have both cylindrical antennas to have this charging system, anyway the antenna in RX section has to be cyclindrical for mechanical reasons. The RX antenna has maximum lenght of 40mm and inner diameter of 22mm. I need to have a charging minimum current of 1A. Distance between two antennas is about 3mm and there is nylon PA12 between them. In TX section we have not particular constraints in the shape of antenna, you can design rectangular plane antenna too. We have 5Vdc 3A current in TX section. I need to have d...

    Not processing more proposals. Follow the Sun is a 50' Solar catamaran. The boat has 2 motors, one in each hull. The motor forward speed is controlled by a 0 to 5v input signal. The motor backward speed is controlled by setting reverse (close contact) and 0 to 5v input signal. Turning is accomplished by reducing the motor speed on one side. Via throttle input or by autopilot command) The requirement is for a throttle circuit that will allow manual and autopilot control. Please contact me for further detail.

Two processors on two separate PCBs will monitor GPIO pins for digital and analog inputs and comparing those values to alarm set points and annunciating alarm status via LED outputs (about 20; green=good, red=alarm). The two micros will communicate between each other via serial ports (converted to RS485 via single chip convertor). A couple other features such as detecting physical key turn-on and time-out-timers will be required. PCBs are being laid out now. Coding should start right away. Will include Ethernet port and Simple GUI for viewing/clearing alarms.

    I am designing two PCBs (a RF emitter and a RF receiver) and I would like to find someone to give me a hand with it. A summary of specs is presented below: - The emitter (Tx pcb) it is like a keyfob. It should incorporate an encoder (HT12D or similar) along with an RF emitter IC and a PCB printed antenna. This board will be powered with a coin cell (3V). There will be only 2 inputs coming into the encoder. - The receiver (Rx pcb) should incorporate a decoder (HT12E or similar) along with a RF receiver IC and a PCB printed antenna. This board will be powered with a single LiPo Battery (3.7V). There will be 4 outputs. This board should also incorporate a LiPo charging management circuit (TP4056 + DW01 + FS8205) and a DC-DC boost IC (MT3608 or similar) since one of the outputs requires 12...

The machine should not use any hydraulic and pneumatic system for Operation. We would be able to give input to the machine through the push button available and also directly through the computer or data stick in case of bulk requirement ( different cable length). If the machine can itself take different cable ( sq mm) and cut it into desired length as per table or input provided in bulk would be great.

There has been a new pcb built with the 675 but with many of the same components as found on the Starter Kit. The new board has some pin changes from the Starter Kit. As much as possible has been kept the same. The new board does have more capabilities than the old Starter Kit. The new capabilities will need to be implemented as a separate project after the basics have been achieved with this project.
