Infrared Remote Controller Using Arduino

Engineeering Projects
circuit diagram of infrared remote using arduino

Here is projects called “Infrared Remote Controller Using Arduino” which allow you to control any type of electrical gadget using any infrared remote control. The project posted here records an infrared message from an existing remote control and give output as required. Here, we use EEPROM memory to store the infrared signal code so that we can use this remote even arduino board is disconnected. Circuit Description of Infrared Remote Controller Using Aruino:- The circuit of infrared remote controller is designed using an arduino board and a IR receiver module.…

LED Running Light Circuit

Engineeering Projects

Various types of running or disco lights are already available on bestengineeringprojects.com. Now here very simple LED Running light circuit using two transistors. Circuit Description of LED Running Light Circuit: The entire circuit of LED running light is designed using two general purpose NPN transistors. The design and working of this circuit are very simple and straightforward. Both of these transistors are configured in astable multivibrator mode. Initially when no power supply is connected, both the transistor drives to cut off region and none of this LED glow. But when…
