Sensor Detection Circuit

I made this specific circuit to replicate many different utilizations of this circuit in: car object detection system, monitoring circuits, and other applications with distance sensors. This specific circuit can be utilized in many different applications that require a sensor to notify if they are too close to various objects, by alerting them with an RGB LED, LCD Screen, and a Buzzer for noise. As you progressively get closer to an object, the LED lights up red, the LCD displays a "DANGER!" statement, and the piezo buzzer starts to buzz loudly. To conclude, this circuit has various utilizations, and acts as a sensing circuit: green = safe (no buzz), orange = caution (beeping buzz), and red = DANGER (constant buzz)!

Specific supplies include:

• Any Arduino - Preferably Arduino Uno R3
• A RGB LED
• 270 Ohm Resistor
• An I2C LCD Screen
• Piezo Buzzer
• 4 Male to Female Wires
• 9 Male to Male Wires

Open TinkerCAD

Collect the specific electronic components: I2C LCD Screen, Piezo Buzzer, 270 Ohm Resistor, Ultra-Sonic Sensor, and a RGB LED

Connect the RGB LED Based upon the schematic

MAKE SURE TO CONNECT THE RESISTOR TO THE BLACK GROUND LEAD PLEASE (to change the resistance of the resistor, simply click on it and change the symbol to Ohms, and add 270, instead of 1)

Designate the wires to each of the RGB LED wires - (Left to Right) Red, Ground, Blue, Green

Connect the Ultra-Sonic Sensor's power and ground

Connect the Ultra-Sonic Sensor's data pin according to the schematic

Connect the I2C LCD Screen according to the schematic

Designate the piezo buzzer pins too

Lastly, follow the block code procedure listed above
