current room temperature with arduino

Image
It is simple basic arduino project you need Arduino Uno Dht 11 temperature & humidity sensor data cable & jumper wire  Please watch this video connection diagram arduino code #include <dht.h> dht DHT; #define DHT11_PIN 7 void setup(){   Serial.begin(9600); } void loop() {   int chk = DHT.read11(DHT11_PIN);   Serial.print("Temperature = ");   Serial.println(DHT.temperature);   Serial.print("Humidity = ");   Serial.println(DHT.humidity);   delay(1000); } Download Dht11 library Zip file

How to make obstacle avoiding robot car with out microcontroller

Image
It is simple robo car made with IR proximity sensor. If IR sensor send signal to relay module then relay on and left motor stop ,robot turn left Right motor connected to battery + & - so right motor always on Parts list- Bo gear motor 100 Rpm IR proximity module single channel relay module plastic box jumper wire 3 X AAA battery or  4X rechargeable AAA battery or LI -po battery 3.7V wheel x2 castor wheel x1 please watch making video
