Hi i am doing this for school project. After connecting the sensor module and transistor using resistor, the next step have the BLUE THING that connects the transistor emitter to the vcc, WHAT IS THE BLUE THING CALLED? The project is due two days later, please answer, i appreciate it...
I made this, cut it switches off whenyou go towards it, and on when I move away. I have adjusted the pot but still have the same problem. Please help. Thanks.

Hi, i am doing this for school project. after the connecting the sensor module and transistor using resistor, the next the step have the BLUE THING that connects the transistor emitter to the vcc, WHAT IS THE BLUE THING CALLED? my project is due in two days, please answer if you know the answer..
i did this thing... my problem if when you out in direct to sun or if the place is bighther the sensor will trigger it will dispense alcohol even no object detected by the sensor. but if you place this to a room that is dimmer compare to outside light it will function well.. do you incounter this kind of problem also?
Because Sunlight has IR rays which triggers the sensor when exposed to outdoor or even in indoors with bright lights these cheap IR sensors malfunction.

Sir I tried this project it works first day perfectly next day only IR sensor light on but sanitizer not coming...plz reply me sir what is the problem...

This is bcs the motor pump u are making gets rusted under water so make hand made water pump not waste money on 200rs make homemade u can change the motor also In homemade one
hello good day sir. can I ask something about this project, and their materials. I need this for my school project this january 2021. materials: Ir sensos- check Dc water pump 12v ( I can't find 6v pump in our place) TIP120 NPN transistor ( I can't find bd140 and TCP32C PNP transistor) 1k ohm resistor- check wire -check battery 12v- check please advice if this materials that i commented is working? cuz I can''t find the same material as yours.. thank you so much
