Real Problems
i will post a pic of robocon egypt 2006, i participated , i saw some real problems , as u see the ambient light is very heavy and shielding didnt work :(, also we were using LDR , the overall results were very bad ...
well, the circuit was an ultrabright red led , and Ldr connected in series with a 10k to vcc (5v) and the output is connected to an inverter ... and we put a pot in series with the Ldr to calibrate ... well , what i intend to use this year is to modulate the emitter at a certain frequency and i will use a high pas filter ok but i want also to use the inverter circuit like i used last year , would that work ? and would that help in that enviroment ( heavy light ) . http://i11.tinypic.com/3zi1z6d.jpg |
