Controlling of DC Motors using MPU-6050

In this project, we are going to control the speed of 2 DC motors using the MPU-6050. MPU-6050 is an accelerometer and Gyro sensor. By moving the sensor in upward or downward direction, the speed of the motors will increase or decrease. By moving the sensor in upward direction, the speed of first motor will increase and the speed of other motor will decrease. Similarly, by moving the sensor in downward direction, the speed of first motor will increase and the...

Interfacing HC-SR501 PIR Motion Sensor with Raspberry Pi

All living beings radiate energy to the surroundings in the form of infrared radiations which are invisible to human eyes. A PIR (Passive infrared) sensor can be used to detect these passive radiations. When an object (human or animal) emitting infrared radiations passes through the field of view of the sensor, it detects the change in temperature and therefore can be used to detect motion. HC-SR501 uses differential detection with two pyroelectric infrared sensors. By taking difference of the values, the average...

Interfacing Ultrasonic Distance Sensor : ASCII Output with PIC Microcontroller

In some of our projects, we may want to measure the distance of an object from a point. Ultrasonic Distance Sensors are the best sensor which provides stable, accurate, precise, non-contact distance measurements from 2cm to 4m. Ultrasonic Sensors can be used to measure distance between moving or stationary objects. Being very accurate and stable, these devices find large number of applications in robotics fields. For example it can be used as an excellent replacement for IR sensors in  a Micromouse. In...

Ultrasonic Sensors

Ultrasonic Sensors are widely used for non-contact  proximity, presence and distance measuring applications. These devices work on a similar principle of sonar or radar which evaluates the target by interpreting the echo from sound or radio waves. It emits a short high frequency sound waves and evaluates echo which is reflected back from the target. Sensors uses the time interval between sending the sound waves and receiving the echo to determine the distance of target. Most of the ultrasonic sensors are equipped with temperature compensation circuit to avoid...
