MOTOR CONTROL WITH LIGHT (ROBOT BUBBLE) SCHEMATIC CIRCUIT DIAGRAM
Motor control involves the regulation of movement in organisms equipped with a nervous system, encompassing both reflexive actions and purposeful directed motions.
Motor control circuits typically consist of two fundamental components, including a disconnect switch and a motor starter, which comprises a motor contactor and an overload relay. It is possible to position a disconnector between the power source and the starter, and in some cases, both the switch and starter can be housed within a single wall-mounted enclosure.
In practice, this design is straightforward and suitable for uncomplicated terrain.
In my engine, I have incorporated two Light Dependent Resistors (LDRs) positioned at opposing ends to detect differences in light levels. This circuit serves to trigger a change in the direction of rotation when the engine is activated, ensuring that specific components are illuminated.
The rationale behind setting a specific reference threshold for the light is to enable continuous rotation of the engine while altering the motor’s speed without the need for halting.
If you intend to utilize LEDs within the circuit to monitor engine speeds and gauge the intensity of light, you can employ this setup for experimental purposes.
Regarding the values of components in your engine circuit, I lack information about the specific transistor values you are utilizing, as you have not provided them. Therefore, I recommend selecting transistor values based on the requirements of your application and the inner strength of the components at your disposal.

Adjust the voltage settings so that they will not move at all in a completely dark environment.
Control Schematic Circuit Diagram:
Two Light Dependent Resistors (LDRs) have been employed in the circuit to detect changes in resistance, enabling the circuit to facilitate right, left, or straight movements.
The provided values in the circuit represent tested values. The selection of circuit element values depends on the desired voltage gain and the voltage requirements of the motor.
In this setup, we have opted for a DC VCD (player) motor due to its lower energy consumption compared to other types of motors. Additionally, we have chosen medium-strength transistors from the BC and BD series to complement the circuit.
