| IR based home automation HOW TO COUNT THE PULSE CODE MODULATION OUTPUT |
| right arun , i got it now. actually , i was thinking on the lines that the pulses are continuous, but the IR sensor would give a burst of pulses which can happen randomly in real time so yes, u need ... |

| How measurement intensity light? Forum -> Electronics |
| hi moon, yes, the pins 11 to 18 of ADC0804 are indeed digital and are the parallel data lines of the ADC interface to the uC.Before u go any further with ur project, I would strongly suggest u go thro... |

| IR based home automation HOW TO COUNT THE PULSE CODE MODULATION OUTPUT |
| well, if there are two timer/counters in the PIC,i think u may need both of them, one in the counter mode to count the pulses and one in the timer mode (internal clock) to measure the time. just start... |

| LCD display |
| hi AK, if u want to keep it very simple then use the 31/2 digit ADC cum LCD driver IC 7106/7126. i.e. if the display counts are less than 2000 counts. I fu want a higher resolution, then u can go for I... |

| shorting mechine control using AT89C51 |
| caze, 1.43A is too high a current for a small transistor like BC337. For that high a current u may have to use a power transistor like 2n3055 or mosfets like like he IRFXX series. just verify that th... |

| software for circuit drawing |
| Another freeware is the PCB123 software which has a huge component library and is fully functional. But as far as simulation is concerned (especially for uC ciruits),I feel proteus is the best though... |

| help with ldr |
| note that an LDR responds in an extremely non-linear way to the light intensity. The resistance of a LDR aries from a few meg-ohms in dim light to a few kilo ohms in bright light (maybe even a few oh... |
