Arduino ST7735 1.8″ TFT display example
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 […]
Arduino Projects
Simple Circuit Website provides many electronic projects and applications based on different types of Arduino boards.
Generally, Arduino is an open-source electronics platform consists of development boards (Hardware) and programing codes (Software) that enable creators, hobbyists, and engineers to implement interactive and automated systems, more simpler and easier.
Arduino based remote controlled DC motor
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
Arduino DC motor speed and direction control with L293D
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

Arduino NEC IR remote control decoder
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
Arduino RC5 IR remote control decoder
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
Arduino with HC-SR04 ultrasonic sensor
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
Arduino and LM35 temperature sensor interfacing
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
