In this Control circuit schematic They explained about sensor inputs (the sensor inputs are connected to the analog inputs on the Arduino board ( A0, A1, A2, A3 ). The input voltages on these pins are converted into a 10 bit integer value
such that the range between 0V and 5V and translated into a value between 0 and 1023 respectively. The ideal connector thus contains 3 inputs per sensor ( 5V, GND, A
) resulting in 12 connection points.) I need clear explanation about this and what type of sensors they using and how they connected ??
Thanks For ur help :) :)
