This is my first post in this forum.
I connected BBB (running Angstrom) and ran the code in this link http://beagleboard.org/Support/BoneScript/Potentiometer/ from browser. Instead of a pot, there’s a LDR-resistor network.
Vdd_ADC 1.8V goes to a 47k resistor.
From resistor, an LDR (9k ohms in light and around 115k in dark). Other end of LDR connected to GNDA_ADC
P9.40 (AIN1) of BBB connected between the resistor and LDR.
On pressing the Run button, the console shows value “x.value = 0.12777777777777777” when LDR is exposed to light.
I removed the source of light (covered the LDR with finger) and pressed Run button. The value doesn’t change. It’s “x.value = 0.12611111111111112”
On pressing the Run button again, the value gets updated: “x.value = 0.40944444444444444”
The value must get updated in the second step itself, right? Why doesn’t it happen so?
