Q&A

Task#7__Make a radar by Ultrasonic Sensor

Task#6__Turn on the LED lights as the distance detected by Ultrasonic Sensor

This is a simple example of using the ultrasonic sensor (HC-SR04) in Arduino where we will turn on a led with the variation of distance and print the distance from an object to the serial monitor.

Task#5___Control Servo Motor’s motion by using push buttons

Task#4___Control DC Motor’s speed by using a potentiometer and a motor driver

 

Task#3___Control RGB LED by using three photo sensors

For this task, we use three Photo sensors to control RGB LED. And an RGB LED is a combination of three LEDs in just one package: red, green and blue. It generates different colors by adjusting the brightness of each of the three LEDs of the RGB LED.

Transistor

Transistor is a semiconductor device which is used to amplify the signals as well as in switching circuits. 

Generally transistor is made of solid material which contains three terminals such as emitter (E), Base (B) and Collector (C) for connections with other components in the circuit.

Task#2___Control brightness of a LED by using a variable resistance

The objective of the task is to control the brightness of a LED by a variable resistance like below.

Task#1___Control three LEDs by using a push button

We use Arduino UNO to control three LEDs by pushing the button
