Overview Thousands of cars are being stolen every day around the globe. So it is really important to protect and secure your car. In this tutorial we will use the SIM808 module to build a GPS car tracker. If you are not willing to use a GPS read this article to find out how to detect location by GSM modules: (Using GSM with Arduino as an alternative for GPS). What You Will Learn Get to know with the concept of GPS Get to know with the sim808 module Build a GPS car tr...

TCRT5000 Sensor Features The TCRT5000 Sensor is used to detect color and distance. The sensor emits an infrared wave and then receives it. TCRT5000 Infrared Reflective Sensor Module is often used in line following robots and object sorting Robots since this module can sense if a surface is white or black. The measuring distances range from 1mm to 8mm and the central point is about 2.5mm. There is also an onboard potentiometer to adjust the sensitivity. TCRT5000 Sensor Pinout This sensor has ...

4 Channel Infrared Module Features This module has 4 IR transmitter and receiver pairs that can be used to detect black and white color as well as obstacles. Each channel has digital voltage output. You can adjust the sensor’s sensitivity using the on board potentiometers. Pinout You can see pinout of IR module in the image below. Required Materials Hardware Components Arduino UNO R3 × 1 4 Channel IR Obstacle Avoidance Proximity Module × 1 Male to Male jumper wir...
