Introduction This project is an extension of the mobile rover project in the Arduino Engineering Kit. I added the following features to change how one can control the rover – Instead of programmatically specifying a set of waypoints for the rover to travel, I control it using my android phone. The inspiration for this project came from remote controlled cars, hence the design – tilt phone forward and backward to control the drive and tilt the phone sideways to control the steerin ...
Machine learning does not have to be complicated models that cannot be deployed to MCUs, it could be a model-free learning algorithm. Here is a video of the final project in action.     The motorcycle balances for about 10 -15 seconds, but further training and changing the incentives of the reward function can train it to balance longer How It All Started Balancing an inverted pendulum is a ubiquitous example used in controls curricula, with lots of available solutions, using concept ...
Story Keeping valuables safe and locked away is important to everyone. While you can have a manual safe, why not build your own safe box and add some smarts to it? Using an Arduino, a servo, joystick and an LCD screen, you can make the electronics for a combination lock safe. An overview of the safe system: This diagram shows the flow of data for the safe. Sensorsa. A joystick that controls the digits displayed on LCD screen. b. Two push buttons that are used to enter and set a new pas ...
  One of the most important things when playing guitar is making sure that the instrument is in tune. Even the best guitar player will not sound any good with an out-of-tune guitar. Tuning guitars by hand using a standard tuner has always been common, but an automatic tuner makes things much easier, and more fun! This Arduino-based project will tune your guitar for you. Here is a video showing the project in action: https://www.mathworks.com/videos/automatic-guitar-tuner-using-simulink-and- ...
I recently came across this "Instructable" in which the user ahmedelsayed93 has created a project to detect obstacles in front of an ultrasonic sensor using Arduino Uno board. What is so great about it you ask, the video shows the ultrasonic sensor mounted on top of a servo motor to make a Radar detector and the plot on his screen makes it look like the radar images we see in movies and weather channels .   The servo motor is controlled using an Arduino Uno which is communicating the sens ...
I recently came across this summer program for high school kids that aims to teach robotics and programming. The course had a few interesting items planned like designing a line following robot, obstacle avoidance robot and a rescue robot. But the students had to one up  their teachers/mentors to show that they are the future and came up with robots that were nothing but phenomenal.   Let me introduce you to a robot that can avoid falling off a cliff. This robot uses the accelerometer ...
