    The project is to make a design that uses inexpensive parts that are ready available/in-stock for a power converter/controller to drive three phase motor on 48 VDC. The controller will have a microcontroller to implement the control algorithm, and a power converter to perform fast switching three phases (upon switching signals) handling about 1 kW total. The switching scheme will follow classic asynchronous switching with three states: positive, zero and negative.

This DIY arcade style boxing machine project can be found at the Arduino Project Hub where you can discover how this guy did it. This pushup counter uses an infra-red proximity sensor to detect your face with every pushup. Not only will it keep track of how many pushups you do but it will also help detect whether you achieved a valid pushup so there’s no cheating yourself in the process. If your face isn’t close enough to trigger the sensor then you didn’t lower yourself down far enough! The Arduino Uno microcontroller b...

The soil for a certain duration provides information related to the moisture status of the soil. The Arduino Mega will collect and process the data received from the Sensors. When a threshold moisture level of the soil is reached, the water will supply accordingly. This is essential because water must be provided to the plant at a particular time for a good yield.

This analogue voltage needs to be converted into a discrete level (0-4) depending upon the value of input voltage in such a way that some hysteresis is added to reject sudden voltage variations due to noise. Following graph shows the relationship between analogue voltage read (%age) from the channel to the discrete level that need to be encoded by the software. Write code that will perform this job. Use this prototype so the code can be tested: unsigned int hysteresis(unsigned int input_percent) Hint: If analogue voltage increases from 9% to 15% encoded step shall be 1 and if it decreases back to 11% from 15%, the encoded level shall remain 1 unl...

This project is a follow on to a previously completed Bluetooth BLE Scanner MIT Inventor App (see project brief attached). The APK can be found in the project files on Freelancer. The objective of the MIT Inventor app was to prove that the BLE scanner concept would work. This follow-on project will to be to extend the concept to an Arduino Nano Microcontroller. See attached PDF for full project d...
