i connected the ultrasonic sensor to the 3.3 vcc and ground and the trig and echo pins to GPIO22,1 when i connect the sensor i get MD5 error:"A fatal error occurred: MD5 of file does not match data in flash!" any help will be greatly appriciated...
It uses flame sensor for detection of fire, also ultrasonic sensor to detect obstacles and Arduino board for processing. The Fire extinguisher along with actuator is used to extinguishing the fire which is been detected. The robot continuously scans for fire. This scanning is performed by Flame ...
ArduinoGPSGSMUltrasonic SensorMajor significant challenge looked by the current reality is the developing measure of wastage (garbage) produced each day. Because of urbanization, population explosion and ill-advised methods for waste gathering, waste is being created on an enormous size. Hazardous ...
The driven oscillation is made by a servo motor, and the oscillation amplitude is measured by an ultrasonic position sensor. Both are controlled by an Arduino board. The frequency of free oscillation measured was campatible...doi:10.1002/pc.24588Paulo Vinícius Rebeque...
