Arduino Obstacle Avoiding Robot In this tutorial I will show you how to make your own obstacle avoiding robot! We will use the Arduino uno board and an ultrasonic sensor. If the robot detects an object in front of it, with the help of a small servo motor, it scans the area left and right in order to find the best way to turn. It has also a notification LED, an buzzer to play a tone when an object is detected and an button for changing the function of the robot (stopped / moving forward). It's very easy to make it! For this project you will need: Arduino UNO Computer Board Mini breadboard L298 motor driver module 2x dc motors with wheels HC-SR04 ultrasonic sensor Micro servo motor Button Red LED 220 Ohm resistor 9V battery holder (with or without power jack) 8 spacers (male-female), 8 nuts and 8 screws You will also need one big (metal) pap...
Build Your Own Arduino Weather Station In this project, we will be making a weather station that measures air pressure, temperature, rain drop, soil humidity and air humidity using Arduino which save the data for data acquisition! or this project, we will be using: - Arduino boards (mine Arduino Uno Rev3) - DHT11 Humidity and temperature sensor - BMP185 Barometer sensor - Rain Drop sensor module - Soil Humidity sensor module - Breadboard or Custom ProtoShield - Jumper Wire In general, the connections are very simple. Follow the instructions and images above, and you should have no problems. Connecting Rain Drop Module the VCC pin on Arduino’s 5V output the GND pin to Arduino’s GND and the Analog Data to Arduino's analog pin 0 Connecting Soil Humidity Module the VCC pin on Arduino’s 5V output the GND pin to Arduino’s GND and the Analog Data to Arduino's analog pin 1 Connecting BMP185 the VCC pin on Arduino’s 3.3...
Complete Guide for Nokia 5110 LCD with Arduino This post aims to be a complete guide for Nokia 5110 LCD with Arduino. I’ll explain what it does, show its specs and share an Arduino project example that you can take and apply to your own projects. Description The Nokia 5110 LCD is very popular among the Arduino tinkerers. These modules are used on wide variety of applications that require some sort of interface or display data to the user. hese modules are very cheap and you can use them with any microcontroller (MCU). Specifications Nokia 5110 LCD 84*48 dot matrix LCD (shows 4 lines of characters) Price: $2/$3 Voltage: 3.3V Module size: 45.2mm x 43.1mm Model: Nokia 5510 Controller: PCD8544 Arduino with Nokia 5110 LCD You need the following components to make this example: 1x Arduino 1x Nokia 5110 LCD 1x Potenciometer 4x 10K Ohm Resistors 1x 1k Ohm Resistor 1x 330 Ohm Resistor Breadboard ...
