logan_dslasher Posted February 1, 2006 Report Share Posted February 1, 2006 i just hope that the wrong value of R1 is the reason why this project is not working... i'll try it with a 4.7k then.. i'll let you know about the result as soon as i have them..by the way. when you modified the circuit for a speaker instead of a buzzer, i think you forgot to indicate the polarity of the speaker connected with pins 14&15.. anyway, i'll try all the possible connection...thanks.. and also, we have replaced the wires with shorter and smaller ones..later... :) Quote Link to comment Share on other sites More sharing options...
