Am I understanding this right ? He connects the arduino directly to the analogue output of the HC-SR04 transducer to then process it.So he skips the part where the HC-SR04 transform the data into a pulse of a certain length. Thanks
his brings me to my last question for the moment, how do I get more range ? Is it just by making a more powerful emitter or will I need to arrange the receivers to ?
The device I am prototyping needs to always be oriented in the direction of a specific target that is always in eyesight.
I am looking for a use between 4m and 14m.
Because I am aiming for outdoor use, this might be a solution but I don't want to have 30degree error on direction
