This post shows how to connect the Arduino with ST7735 160×128 SPI TFT module. This type of TFT is a small size, low cost and easy to use. In this example I used the TFT shown below (ST7735S): Generally it
This topic shows how did I build a simple remote controlled DC motor (speed and direction of rotation) using an Arduino UNO board and an IR remote control. I used Car MP3 IR remote control which uses NEC protocol and
This example shows how to control a DC motor speed and direction of rotation using Arduino UNO and L293D motor driver chip. The L293D quadruple half-H drivers chip allows us to drive 2 motors in both directions, with two PWM

After the decoding of an infrared remote control which uses RC5 protocol, now I’m going to decode a remote control uses NEC protocol (this example works with both NEC and extended NEC remote controls). Arduino RC5 decoder topic link: Arduino
This post shows how to decode IR remote controls which use the Philips RC5 protocol with full hardware interrupt method and without using any external library. About RC5 protocol: The RC5 has 14 bits per 1 code transmission, the 14
This post shows a simple interfacing of an Arduino UNO board with HC-SR04 ultrasonic sensor in order to build a distance meter with a range up to 4 meters. The HC-SR04 ultrasonic sensor module can measure distances form 2 cm
This article shows the interfacing of the Arduino with LM35 analog temperature sensor. The measured temperature value will be displayed on 16×2 LCD screen. About the LM35 temperature sensor: The LM35 temperature sensor is a three pin device (VCC, OUT
