Arduino-controlled self-balancing dicycle

Posted on by Leave a comment

XenonJohn’s has made this two-wheeled self-balancing scooter, which is Arduino-controlled and uses the ADXL345 accelerometer and the ITG-3200 MEMS gyro together to form an Inertial Measurement Unit (IMU). The Arduino MEGA board analyses the outputs from the IMU and signals the Sabertooth dual 25A motor driver (which in turn drives two 24V brushed gear motors) to maintain the balance while you are riding. A 4×20 character LCD provides you status updates during the ride. The motors are powered with a 24V battery, while the control circuit including the Arduino receives the power from six AA batteries.

Add a reminder to your washer

Posted on by Leave a comment

Most washers don’t have a built-in reminder. Mine doesn’t have either and a lot of time I have forgot my clothes inside it after they are done. The wet clothes smell really bad if they are left inside the washer for a while. If you have a similar issue with your washer, you might want to build this project which adds an audible reminder to the washer that will beep when the clothes are done.

Reminder for washer

This project is based on an accelerometer that continuously senses the vibration of the washer when it is running. When the clothes are done, the washer stops and so does its vibration. The PIC12F683 microcontroller turns on an alarm when the accelerometer doesn’t get any movement for a preset time interval.
