Musical Lights In this project, we are going to create RGB light flashing in sync with a tune played on the speaker. We will build this project on top of Musical Tunes project. Please refer to that project before you proceed. We will use RGB LED and generate variety of colors with each beat of […]
LCD Screen Display Board We can use an LCD screen to display text, numbers and symbols. We will see how can we use the LCD screen with Arduino to use it in various projects. LCD stands for Liquid Crystal Display. It has specially engineered crystal chains which can be oriented in particular way when electrical

Indoor Weather Station The most important indoor weather parameters useful to us are air temperature and relative humidity. Relative humidity is the percentage of amount of moisture present in the air compared with maximum amount of moisture possible at that temperature. Typical indoor temperature range is 10°C to 35°C. Relative humidity can vary between 0%

Car parking sensor detects the distance between car and the obstacles around it. A buzzer beeps faster or slower depending on whether the car is close or away from the obstacle to provide perception to the driver. We can design a similar system using a ultrasonic range sensor and an active buzzer. Ultrasonic range sensor
In an access-controlled parking area, there needs to be a boom gate to allow cars in the parking area to exit out but prevent unauthorised entry from outside. This gate detects presence of a car at the gate and opens the gate for it to go out. However, this gate remains closed and does not
