Ultrasonic Sensor, HC-SR04

In this blog, I will share how the HC-SR04 Ultrasonic Sensor works and how to use it with the Arduino Board. You can watch the following video or read the written description below. Hardware: Ultrasonic Sensor HC-SR04 Arduino Board Breadboard and Jump Wires Circuit: […]

Heat sensor; LM35

Heat sensor! How cool is that !! okay, introducing LM35 . LM35, an integrated-circuit temperature sensors, with an output voltage linearly proportional to the Centigrade temperature. let’s measure temperature . Hardware: Arduino Uno LM35 Circuit: This heat sensor is very useful yet easy to use. From this circuit diagram , we can say that it’s very […]
