ung sandwich.. may nakita akong ganun na link dito e... and ginamit naman e, ldr.... anu ba pinakamaganda sa lahat na gamitin? pwd din bang gamitin ang Ir as proximity sensor>? nag lagay lng ako ng led as indicators... hehe, hnd ba po pwd ung ganun? pag actual na e, nag luluko na hehe... hnd q ma read ung output voltage e.. wala kasi aqng tester.. badtrip
1. LDR- mas madali matune ang sensor.
2. Phototransistor- maganda ang sensing capability but it's difficult to calibrate.
Definitely IR sensor can be use as proximity sensor and that's no doubt. again, proper calibration lang.
LED indicators - it consume less voltage and not that noisy. Motor causes noise on the circuit, so what i did i separated the power source for the motor from the power source of the sensor. Remember that sensing capability of your sensor is dramatically changed when the power source is getting lower (this happens when the motor starts to run).
Nung gumawa ako ng line follower I didn't use any kind of tester. Purely based from equations. And that was it.
