This document describes 7 Arduino projects that utilize basic electronic components like breadboards, jumper wires, batteries, LEDs, 7-segment displays, sensors, and motors. The projects include monitoring temperature and humidity with a DHT11 sensor and 7-segment display, monitoring body temperature with an LM35 sensor, 7-segment display and RGB LED, using a potentiometer to control a 7-segment display's blinking, controlling a stepper motor's speed based on temperature, activating a relay to power an appliance based on temperature readings from a DHT11, measuring AC current with an ACS712 sensor and displaying it on a 7-segment display, and measuring distance with an HCSR04 sensor and indicating the reading
