Abstract: The work presents the realization of a solar cell orientation system using a pyramidal sensor. At the base of this system is the pyramidal sensor that captures the luminous flux and transmits it in the form of information to the block responsible for signal processing. The main component within this block is the operational amplifier AO 741, which amplifies the signal before reaching the motor drive block. Within this block we will meet an H-bridge that has the role of changing the direction of the current in the motors, thus resulting in the change of the direction of rotation. In this way, going through all the blocks described, the signal resulting from the pyramid sensor leads to the finality of the movement, namely, the top of the pyramid is oriented towards the sun. When the light flux will fall from a different angle on the sensor, the process will start again, reorienting the pyramidal sensor.
