The circuit below has been built using Control Studio^® software. The circuit has two sensors - a light sensor and a push switch. These are connected to an AND gate. Both sensors must be ‘ON’ for the AND gate to operate a motor.

The light sensor must be connected to a sensor unit. Also the voltage output from the AND gate must be amplified by a Darlington Pair module before a motor can rotate.

The modular circuit is built by selecting an INPUT or PROCESS or OUTPUT etc... The module is then dragged into the design sheet area of the screen. Each module is connected by wires or by connectors. The connectors are found in the Gallery and are simply dragged across into the circuit design sheet area.

Once the circuit is put together, it can be tested by using the software’s simulation option (dia. ‘A’) When this is selected, the animated circuit operates as a real circuit.
In the case of the circuit shown above - both the input sensors (push switch and light sensor) must be ON / HIGH/ TRUE before the processing AND gate activates the motor. The darlington pair amplifies the current / voltage, providing enough power for the motor to turn.
