How to make Automatic Sanitizer dispenser
Circuit diagram


Components required
  • IR sensor
  • LM293D motordriver
  • Jumper wire
  • Battery
  • Battery cap
  • DC pump
  • Empty container
  • Fuel pipe
  • Zip tie
Construction 
As we can see in the circuit diagram connect the Vcc pin of IR sensor to 5v of the motordriver. Connect the Digital pin of the IR sensor to the C1-A of the motordriver. Connect the ground pin to the common ground pin of the motordriver. Connect the 9v battery to the motordriver. Connect the DC pump to the M1 pin of the motordriver board.

    Can we add timer to the motor?

      No, then we should add on arduino board then it is possible to add timer

Information about H-Bridge

Information about H-Bridge H-Bridge module L298N 2A Dual motor driver module with PWM control An H-bridge is a simple circuit that lets you control a DC motor to go backward or forward. You normally use it with a microcontroller, such as an Arduino, to control motors. When you can control two motors to go either forward or backward – you can build yourself a robot! H-Bridge concept Here’s the concept of the H-bridge: A DC motor spins either backward or forward, depending on how you connect the plus and the minus. If you close switch 1 and 4, you have plus connected to the left side of the motor and minus to the other side. And the motor will start spinning in one direction. If you instead close switch 2 and 3, you have plus connected to the right side and minus to the left side. And the motor spins in the opposite direction. The H-Bridge circuit You can build an H-bridge with four transistors. If you’re not sure how the transistor works, I recommend ...
