    Need help working with ULN2003A

    Hi, I would like to know how do you built a code that have three input, let say Input 1, Input 1, Input 3, and Input 4 which correspond to 110, 101, 011 and 111 respectively. Note that 1 indicates 5V and 0 indicates 0V (ground). When the code read 110 (input 1), for example it will output the...

    pic16f690 and stepper motor

    Thanks for the reply. That is really informative. However, I want to ask you another question. I come across this video on youtube. stepper motor controller with pic and c code - YouTube and trying to understand how he built the code, but I cant figure it out! Attached is the code that I...

    interface the output of PIR sensor to PIC microcontroller

    Thanks for the reply. That is what I am thinking, I will use voltage divider to reduce the voltage, but what is the next step? How im gonna make the output of the sensor as input of my PIC, I am using PIC16f690 by the way. To clear your doubt of my pir sensor, i give u this video that i just...

    interface the output of PIR sensor to PIC microcontroller

    Hi guys, I just wanna ask how do you interface the output of PIR sensor to PIC microcontroller ( so that output of PIR sensor = input of microcontroller). I have already built a PIR motion sensor circuit and it working well. I have an output of 0.1V if there is a person detected (LED ON), an...
