Steps
- Mount the Peltier module between the heatsink and a small test plate.
- Wire the Peltier to the L298N driver and add the temperature sensor.
- Program a PID loop that heats or cools to hit a setpoint.
- Tune the PID and record how fast it reaches setpoint and how steady it holds.
- Measure power in vs. cooling achieved to estimate efficiency.
- Document the controller and results for your portfolio.
