Looks like he uses the emitter diodes as receivers (like photodiodes). He configured the LM386 to maximum gain, according to datasheet it should be 200 max, but maybe with the short between the gain terminals (1 and 8) its higher.http://www.instructables.com/id/Mousebot-Revisited/
the problem is there are two Infrared emitters but I see no detectors. And what's up with the switch from the Mouse click?
The IR-LEDs detect the part of the ambient light they are sensitive to. Since there will never be a 100% equal light intensity on both sides a small difference will always exist, it's being amplified by the LM386.i meant the switch he placed in the front of the device. Not the toggle switch. The one he detached from the mouse.
what is received by the emitter diodes? Can emitter diode receive a signal from nowhere? or does it receive the signals sent by itself?
Not necessarily. The robot will turn to where the light intensity is higher, may be a glass wall with a lamp behind itYeah that's what i also thought about that momentary switch. and that ambient light thing is new to me.. and if im right that's to keep the mouse from walls aside. is that so.
You better stay with the original specification of the relay, i.e. 5V coil voltage.and one more thing the relays i found in the market have pins number from 1 to 8. but here he's got pin 11 and 13 and so. Is there any standard to recognize what is the NO and NC and what is Coil? Will it be okay if i use a 12v relay instead of 5?
