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...
An ultrasonic sensor generates high-frequency sound (ultrasound) waves. When this ultrasound hits the object, it reflects as echo which is sensed by the receiver as shown in below figure. Ultrasonic Sensor Working Principle By measuring the time required for the echo to reach to the receiver, w...
