We need th...alarm to a cellphone when find an alarm. We have an UPS connected with serial port to an modem, we need develop the software for this microcontroller. We have the UPS protocol , so the design consist in read the flags from the UPS via RS232 and if something wrong happend on the UPS the modem send the SMS to a cellphone. The microcontroller neeed to keep the cellphone number where need to send the SMS and also it can receive via SMS new cellphone numbers or erase other from the list. All project that we need is related with hardware becuase we already have the hardware. You can develop the project in C witht he microcontroller that you prefer. The microcontroller need to keep the number and male some basic functions like send the actual status or res...

Project to design a piece of equipment which can run through our production process, and record some conditions. The system will consist of a microcontroller, 2 pressure transducers, and a humidity/temperature sensor. It will be measuring conditions from inside a dryer at ~ 110 degrees. The code needs to make it simple for the data from these sensors to be recorded onto a storage device (usb/sd card) which can then easily be uploaded onto a PC and transferred into an Excel sheet. The project is expected to be completed within the next 3 months or so, and over that time the code may need adjusting in order to make the equipment a reliable piece of kit.

I need to chill a tank of water about 12 litres to a specific temperature in the fastest amount of time, and I will also need to stir the water in the tank and dispense the water out. You will need to design the components and give me the spec...components and where to buy online. If you are able to build it, please indicate that.

Code debugging required for IAR Embedded Workbench project designed for stm32f101 microcontroller controller

...Signals from a handful of sensors are received. 2. Signals are processed by software on a microcontroller to produce the appropriate output signals. Software initially only needs to process the input signals by outputting a signal opposite to the input signals. This is to counteract shaking. The programming language and microcontroller used needs to be scalable in order to perform more advanced signal processing later on, and do things like display information on an LED screen. I essentially need a computer that can receive input signals from sensors, do calculations, and then output signals to power electronics and data to a monitor. 3. Power electronics that can take signals from the microcontroller (computer) and then control the force generated by small ele...

I have a project which has a following structure: - there is a microcontroller controlling the DAC output - the DAC output is going to the two stages of amplification(op-amps) which is feed to the base of Darlington transistor - the collector of transistor is feed to the transformer(primary side) - the other end of primary side of transformer is triggered using a MOSFET, and when triggered it is connected to the ground The schematics really should be OK, but I seem to have problems finding a mistake. I have made the PCB already and it is not working. I need your help so we can find a mistake together. I can provide all required measurements you need, but you also need to recheck the schematics and PCB design.
