i ve connected the ic7448 and common cathode 7 segment display as per the circuit diagram i got in the internet.. but i dono where to connect the pins 3(LT),4(BI/RBO),5(RBI) of 7448.. are these pins to be grounded or connected to the positive supply?? can someone post the working diagram for...
i am buiding a linetracer bot of dimension 30x30 to be used for carrying 4 blocks each of weight 100-150g.. i am using 4 wheels each of diameter 5cm. i am using l293d for driving the motors. Two motors on the leftside are connected together so that they can be driven simultaneously and same with...
i am using TRIC V1.1 for writing codes in c for the philips microcontroller P89V51RD2.. i saw a header file named dcmotors.h and function named runmotor(motor_number,direction,speed).. i have no idea how to use this function.. can anyone help me out pls?
whenever i connect 8 ir sensors(for line tracing) to LM7805,it gets heated up in no time.. i tried using a heatsink.. but the heatsink also gets heated up.. i supplied 12v to 7805.. can anyone suggest a solution for reducing the heat dissipation from 7805??
i made an ir sensor for line tracing using lm358 as a comparator.. i am getting the lm358 output as 2.5v.. so naturally when i connect it to the microcontroller, mc does not respond to the sensor.. can anyone suggest a solution for increasing the output voltage of lm358.. i dont wish to change...
