- Figure 1. This circuit works by inhibiting movement in one direction but allowing movement in the other direction when the motor retracts from its end position
- Figure 2. This circuit shortens one input of the H bridge to ground so that movement is possible only in the other direction by turning on the other input
- Figure 3. This circuit interrupts the connection to the driving circuit of one input and sets the input to low using a pulldown resistor
- Figure 4. This circuit is the same as that in Figure 3, and it works with phototransistors without modification
- Figure 5. This circuit is the same as that in Figure 4; the value of the resistors depends on the parts you use
