I’m developing a small “suiveur solaire” that pivots a solar panel like a robotic arm. The build is Arduino-based and must deliver three key capabilities: • Object manipulation • Precise movements • Automated tasks Here’s the vision: two or more servos (or stepper motors if you prefer) will drive an articulated arm that keeps a mini-panel pointed at the sun throughout the day. When the panel is not in use, the same arm should be able to pick up lightweight test objects so I can demonstrate its dexterity. Everything has to run autonomously once powered, with calibration routines and a simple override through the serial monitor or an attached push-button interface. What I need from you – Complete, well-commented Arduino sketch written in C/C++ – Schematic or Fritzing diagram showing every connection – Parts list with suggested motor models, light sensors (LDRs or photodiodes), and power considerations – Short README that explains setup, calibration and how to trigger the automated demo cycle I already have an Uno, breadboard, and a set of SG90 servos, so feel free to build around those unless you see a compelling reason to upgrade. Code must compile on the current Arduino IDE without additional paid libraries. Delivery is accepted once the sketch tracks a lamp in a basic bench test, performs a repeatable pick-and-place routine, and returns to its starting position automatically.
