-### Week 5 - 11 May
+### Week 23 - 29 March
+Decided on the project idea.
 
-### Week 12 - 18 May
+### Week 13 - 19 April
+I researched ideas for implementing the project and made a list of necessary materials.
 
-### Week 19 - 25 May
+### Week 20 - 26 April
+I wrote the initial documentation.
+
+### Week 27 April - 3 May
+I ordered the components.
+
+### Week 4 - 10 May
+I tested the components and assembled the hardware part of the project.
+
+### Week 11 - 17 May
+I worked on the project's software.
 
 ## Hardware
 
-The system is built around the STM32 Nucleo-U545RE-Q microcontroller. The sensory hardware includes a DHT11 temperature and humidity sensor , a rain sensor , an MQ2 gas/smoke sensor for safety , and an RC522 RFID module for secure access. Outputs and physical movements are driven by SG90 servomotors , an active buzzer , an RGB LED module , and an I2C-enabled LCD1602 screen for displaying system data.
