Hello guys!

I’m doing a touchless automatic hand sanitizer dispenser by using TIP32C and ir proximity sensor module. Have any of you done this?

If you have done, I hope you can help me. After giving power to the circuit the pump is getting continuously on, in TIP32C if I'm giving 9V to the emitter then without giving any voltage/current in Base terminal I'm getting the 9V in the collector terminal. The transistor is not working as it should work. I have tried to change the transistor but the result is same. Any. Suggestions what to do now?

Thank you!
