The purpose of this experiment was to obtain a basic knowledge on digital electronics and in turn set the stage to perform the analysis and design of complex digital electronics circuits. It also served as an opportunity to learn how the motion sensor worked by using it to turn the LED on/off. This was done by examining results that were brought forth after carrying out the experiment. The results were analyzed and observations made in order to draw accurate conclusions from the entire process. The experiment was carried out on a breadboard and an Arduino, a board used to prototype experimental electrical circuits and by following step by step instructions to build the circuit and to observe the results there after in order to draw conclusions and relationship between the output produced and its logical components from the constructed circuit. The purpose of the Arduino was to control the motion sensor and store the results. The report draws upon mostly primary sources such as the results of the experiment itself and books based on the subject matter it was seen that the circuit is only observed to produce an output of logic high (1) only when there was movement that changed the infrared waves.
