- Motor-control scheme yields four positions with two outputsFigure 1 shows how to position a mechanical device into four discrete positions but with only two free outputs and one free input from the control system. The position depends on a set of cams and four...Jan 21, 2025
- Active pullup/pulldown network saves wattsThe control circuit in Figure 1 presents a relatively low input resistance and thus imposes a low value on external pulldown resistor R1 to provide the desired low-level input voltage. In turn, R1 wastes power by...Aug 16, 2022
- Circuit Provides Bidirectional, Variable-Speed Motor ControlDuring the development of systems that include small motors, a simple, bidirectional motor controller with speed adjustment may be helpful. Figure 1 shows such a controller. The circuit uses everyday components...Feb 2, 2022
- Decoder Lights the WayA two-line-to-four-line decoder indicates status even when both signal lines lose power. To display the status of two digital outputs, you can simply connect an LED and its resistor on each output. You must, however,...Jul 30, 2009
