Using AVR Timer/Counters: Pulse Width Modulation Modes Two excellent tutorials have already been written about the AVR timer/counters‚ and I want to fully acknowledge this excellent work. The tutorials are by abcminiuser (aka Dean Camera) on the this forum. It’s not my purpose to steal any of Dean’s thunder‚ since I know he plans to explain PWM and has already started that section of his tutorial. It seems to me that PWM is complex enough that it can bear explaining twice‚ and it seems that

task is to implement the Sliding Window Protocol (SWP) in java. However‚ the sample code provided in the lecture notes is in C. Therefore‚ this main task is divided into the following sub-tasks: Port the SWP code to Java Implement missing timer related classes and functions The following sections will cover these three sub-tasks. Porting the code Minor changes were made in order to change the syntax of the code to Java. As seq_nr was not specified in the given files‚ it was replaced

hypothesis will be tested by using a model car‚ a spark timer‚ and timer tape. Procedure 1.Obtain a model car‚ spark timer‚ half a meter of timer tape. 2.Tape the length of timer tape to the back of the model car. 3.Feed the timer tape through the spark timer‚ setting the timer to 10 MHz‚ and turning it on. 4.Turn on the model car. 5.Allow the car to run until the timer tape has been run completely through the spark timer. 6.Remove the timer tape and record the dashes on it‚ the time elapsed

meter stick and a timer‚ a Spark Timer‚ a Photogate‚ and a Motion Sensor. Each method was different but overall‚ our velocities were very similar. Using the meter stick and timer‚ our velocity was 0.22 m/s. With the spark timer‚ our velocity was 0.26 m/s. Next‚ the velocity found with the Photogate was 0.325 m/s. Finally‚ when we used the motion sensor‚ we found our velocity to be 0.34 m/s. This lab is prone to some mechanical and human error. First‚ the meter stick and timer method. This method

The University of Adelaide Assignment AMP1 – Ultrasonic range finder Introduction The aim for this assignment is to write a program for the ultrasonic range finder. It is similar to the sonar system‚ which emit a time-limited ultrasonic wave and receive the echo of the signal. The delay between transmission and reception of the Signal can be used as a measure for the distance at which the object is found. The process shows below. Overview The microcontroller program needs to implement
