Thank you Ogu Reginald. You are right the Load will consume 10A thought of using BTA25 triac because using high rated Triac will produce less heat (this is my assumption). Is it necessary to use snubber circuit ?. Long ago i faced a issue, connected 30A relay with opto coupler and controlled by...
Hi Friends i'm in need of circuit which should switch (Hot switching NOT neutral) 2500 watts inductive load from micro controller. Please explain about when and where to use snubberless Triacs. What current rating Triac should i use for the specified load. Thanks in advance.
My project is to detect continuous IR signal, once the IR path was blocked for more than 200ms it should sound a buzzer. So created a IR transmitter with 38Khz using 555 at one end. TSOP1738 connected to PIC micro controller at the receiver end. My observation is once the IR path was blocked...
Getting error as "Option Invalid Bad Option:31757" while build. Using CCS PIC 4.078.
Micro controller used : PIC18F4580
Please help me to come-out of this error...

Last sunday went to the factory and had a look on that... There the match sticks are collected in a tray and dropped in side the inner box of the match box. A brush is rotating over the filled box to remove the excess sticks. Sometimes what happen is the brush remove more sticks than the...
Please go through the link. At 2:50 seconds we can find how the sticks are feed in to the inner box. I Didn't have any clue how to proceed further with this... Suggest me your idea. Give me a week time this weekend i am going to the production plant. Will come up with more answer for your...
Need to do a project to count N number of sticks, once the number matches it should do some action (need to fill the match box). Please suggest me a better idea to count matchsticks...
In the circuit unfortunately i put 5 leds. Actually used 4 LEDs. 4 leds X 3V = 12V. Paralleled two sets of 4 leds. Used Red color LED from Everlight.
Should that be 2p4s array of LEDs per segment? => Yes.
After changing to 10K i wrote data 0x00 (Blanking) to digit 2,3,4,5 and 6. Wrote data from...
Sunny i replaced 470K resistance with 10K but still facing the same problem.... Any idea about how MAX7219 refresh the segments ?. Is there any other technique to pullup ?..
Created six digit LED seven segment display with 8 leds per segment. Totally used 8*7*6 = 336 LED's. Connected all 'A' segment, 'B' .... 'G' and connected to MAX7219.
Used DS1307 (RTC) and read using 89s52. The problem im facing is if i enabled set segment 1 with value 1 means im able to see 1...
