I have a bot with good wheels and 200RPM motors on each wheel manual driven. I was thinking of automating it with my arduino and some sensors. I don’t have any specific idea of its applications. Hope someone might suggest something interesting. Waiting for suggestions!!   Manually Controlled Bot Arduino mega          Few 16x2 Displays Ultrasonic Sensor

HC-SR04 is an ultrasonic sensor which works on the principle of ultrasonic waves. Basically it creates a pulse depending on the distance from the sensor. It has two eyes like structure one of which transmits the waves and the other acts as receiver. The sensor has 4 pins VCC, TRIG, ECHO, GND. When the sensor is triggered by sending a pulse to TRIG pin, it sends a pulse through ECHO pin which can be measured. 1.       Parts needed: Arduino, wires, Ultrasonic Sensor (HC-SR04). 2.       Connections: VCC pin to Arduino 5V TRIG pin to Arduino pin 11 ECHO pin to Arduino pin 12 GND pin to Arduino GND 3.       Code: void setup ()   {   Serial.begin( 9600 ); //Sensor TRIG pin to pin 11 pinMode( 11 , OUTPUT); //Sensor ECHO pin to pin 12 pinMode( 12 , INPUT);   } void loop ()   {   int duration, distance; //to send trigger pin to pin 11 by activating it ...

Connecting LCD to Arduino to display various things is fun if you know how to. It is very simple just follow the simple steps. Gather the things necessary to do so like: Arduino (mega 2560 for example), LCD display(16x2), Jumper Wires, Potentiometers (1k/10k). Make the connections as shown in the circuit diagram. I this example we are using Arduino mega 2560. You can use any of the arduino just the connections and the coding will change. LCD 1(VSS) to Arduino GND LCD 2(VCC) to 5V LCD 3(VEE) to Arduino GND via potentiometer (10K) LCD 4(RS) to Arduino pin 12 LCD 5(R/W) to Arduino GND LCD 6(E) to Arduino pin 11 LCD 11(DB4) to Arduino pin 5 LCD 12(DB5) to Arduino pin 4 LCD 13(DB6) to Arduino pin 3 LCD 14(DB7) to Arduino pin 2 LCD 15(LED+) to 5V via potentiometer (10K) LCD 16(LED-) to GND         The pin 3 potentiometer will control the contrast of the display. The pin 15 and 16 are for the backlight and the potentiome...
