ARDUINO Burglar Alarm Using Infrared Emitter-Detector pair
Grab Alarm Using arduino + LDR + piezo buzzer
Can you please tell me how to learn programming arduino
Potentiometer doesnot play a much important role. test it.
0k....but if i wanna include potentiometer then where should i connect it in the circuit????
Hi Aaryas , i haven't actually made use of the potentiometer . I have listed it as a requirement since you might have a different pair of IR-LED which work at a specific voltage level , so the Potentiometer can prove to be handy in adjusting the voltage to your IR LED . Hope this helps.
where is potentiometer in this circut diagram

hi i'm new here, i want to ask, based on your circuit diagram you didn't use potentiometer..but you used it...my question is where should i put the potentiometer,,,thank you
bro can i use more than one pair of emitter detector...i want to make track of near abt 6 pair of ir...my project topic is "vehicle movemnt based smart street light with external light sensing"plz help me to get the code respect to this project...thnx in advance
Can i get the screenshot of the code along with the error ? . It would be easier for me to debug that way . I guess you have either not written the code for the buzz method or perhaps you have named it something else by mistake . Just add a screenshot and il help you out .
I get the error "'buzz' was not declared in this scope" when I try run the code on Arduino.Any help?
Please check if you provided Vcc to the correct leg of the IR sensor . This should solve it . Are you using these type of IR led Pairs or some other mounted sensor ? .Do attach a picture of the IR pair , if the problem persists .

Thank you man! You helped me a lot. But I have a doubt. Why is that the amount sent by the emitter is more when there is an obstacle. For example, my emitter sends 1020 when there is an obstacle and sends 1019 when there is not obstacle?

Love this project :)!try building the circuit with circuito.io - you'll get a detailed schematic and code.
