  ST7735 LCD With Arduino Uno and Arduiono Nano (TUTORIAL) Hi. Today we learn about 1.8 inch ST7735 LCD TFT color display. We will use here Arduino uno and Arduino nano for this tutorial. it will be pretty cool . let us start .   The ST7735 TFT display is a 1.8″ display with a resolution of 128×160 pixels and can display a wide range of colors (full 18-bit color, 262,144 shades!). The display uses the SPI protocol for communication and has its own pixel-addressable frame buffer which means it can be used with all kinds of micro controller and you only need 4 I.O. pins. To complement the display, It also comes with an SD card slot on which colored bit maps can be loaded and easily displayed on the screen .

....................................................................................................................................................... Earthquake Detection Device      This is a simple project where we will learn about an easy and efficient way to Detect the the presence of earthquakes ..............................................................................................................................................     For this project we will need following materials.  •  A heavy weight pendulum . •  A warning led  •  A conducting ring wide enough to pass in the conducting wire •  A power on -off  switch. •  Cable lugs . •  Pillars  to  stand in the  whole  setup. •  6 or 12 V Battery or  Supply •  A buzzer and a board to hold the setup. ................................................................................................................................................................... Earthquakes can occur on by various reasons like shifting o

SMART ROBOT CAR  This smart robo is based on arduino , and canwork in 3 modes .... all these modes are  selected by a common android app 1st  mode  : Inbuilt  App  Joystick    working via the app inbuilt joystick command were we can use joystick to control   robo like a    RC car.          2nd mode : Voice controlled robo      Here you can give input to the robo with voice commands. 3rd mode : Autonomous mode      Here the robo will use its ultrasonic sensor to find free way and avoid collision  with objects or      wall. 4th mode : Line follower (optional).      Here we are giving you the option of line following if you need you can active.   5th mode ; IR remote control (optional). This option is also available here.if you need you may active.  ____________________________________________________________________ Download link for app => ------------------------------------------------------------------------------------------------------ Spare parts (needed)               => 1-
