Picaxe 18X

The Picaxe 18X microcontroller is a digital device. It reads digital inputs that is binary numbers(0,1) where 0 means low and 1 means high. When the voltage is less than 3V, the input signal is been read as low(0) and when the voltage is greater than 3V, the input signal is read as high(1). This microcontroller also has pins that can be used as analogue inputs. This implies that we can read an analogue signal by changing each of the 8 bits of a byte as binary numbers. And this would be in the form of binary numbers. As we know that the byte variables range from 0 to 255, therefore the code has to be on this base. The input values from analogue to digital pins is stored in byte variables.
