This is how I see it (please correct me if I'm wrong?): A DC motor Some gears A potmeter A motor controler (also reffered to as a speed controller?) The motor controller receives a signal (in our case from the Arduino) which tells the servo to move to a specific The meter returns the TDS value in ppm (parts per million—mg/L). I wish to identify the different components of a standard servos. The following involves the basic connection of MQ7 and Arduino board and the use of this library. 8 stars.
