Comment on ADC 0808 by qaisar azeemi

i got the error…. ALE pin should not pulled high. it should b kept floating in this circuitry; because ALE is not LEVEL sensitive …. it is EDGE SENSITIVE PIN. it will only trigger on high to low (Falling) edge. so my circuit started working on disconnecting the ALE pin from positive rail of my bread board.

Comment on PING)))™ Ultrasonic Distance Sensor by Ultrasonic sensors

Ultrasonic sensors are absolutely essential, for organisations that use large, heavy vehicles – when used for reversing. However, they are also very useful for smaller vehicles, though they can manage without them. In both cases, accidents are substantially reduced.

How can the sensor function when there are so many resistances i.e wheatstone bridge case?
What is the suitable method to measure the resistance when the sensor is applied?
