1. A code that can read at least 2 analog signals separately, with no more than a few hundredths of a second delay. 2. A code that able to send an Analog Out (AO) signal as a synchronous 60Hz signal. This is for the control frequency of the Inverter when the grid is out, meaning a reference frequency is required. Can send out an AO simultaneously while the Arduino Mega is running through its code loop to monitor the system. The Mega is capable of that; of a 60Hz AO continuously. To top it all off that microprocessor will have to continuously communicate with the Mega, so it knows when to turn on that AO signal.

Looking for an experienced EE to design a PWM controller that can switch 24 channels of 5-24 volts with a maximum of 15 amps current for at least the first 4 channels and max 5 amps on the rest (15A max for all channels is preferable). Either way, a max of 40 amps total current. I have in mind that an LED controller chip would be used to provide the I2C interface and PWM control, and then connect that to FET's to switch it, but open to alternative design proposals. Intermediate deliverables will be regular progress updates and design review. Final deliverables shall be 2 tested & working assemblies plus all design and manufacturing files, preferably in Eagle CAD. Please provide a portfolio of past work upon application.

We are a french IOT Startup and we need support in the development of our prototype, mostly for the electronic and PCB design. you will find below a descriptio of our solution and attached our product specificities. Stop Voleur is a connected wearable which prevent the loss and the theft of smartphones. Hung to a watch, a bracelet, a bag or a jacket, Stop Voleur is connected via Bluetooth to your smartphone and triggers an alarm as soon as it is spirited away from you. The further you are, the louder the alarm is. Thus, in case of theft, the robber is forced to give up the phone and leave shamefully. In the event of loss or omission, you are immediately notified by the alarm and just have to pick up your favorite item.
