How to make an obstacle avoiding robot

In this article we will learn how to make an obstacle avoiding Robot ourself,I have listed some steps in making it below. Materials 1.arduino Uno 2.motor driver 3.switch 4.servo motor 5.battery connector 6.wheel 7.ultrasonic sensor 8.four DC motors. Now the steps:  Step 1: making the chasiss The chassis is the frame work of any robot i made mine from plywood so if you can't get that you can use a thick cardboard or cartoon. Step 2 : connections (a)Gum the Arduino uno to the chasiss with either a gum or a double sided sticker (b) connect by plugging the motor driver to the Arduino. (c) also gum the motors to the chassis. (d) connect the motors ,servos,sensor and the driver to the Arduino by following the circuit diagram below B You can upload the code below to the Arduino Uno board. # include <AFMotor.h> # include <NewPing.h> # include <Servo.h> # define TRIG_PIN A4 # define ECHO_PIN A5 # define MAX_DISTANCE 100 # define MAX_SPEED 80 // sets speed of ...

How to make an rc drone for begginers.

Drones are made to hover freely in air and perform tillt and bending with the help of four brushless DC motors with fan blades each which produces air when spinning,the air it produces downwards helps the drone to gain lift.Drones bends or hover with the help a ECS (electronic control speed ) which changes the speed of two diagonal blades which results in bending of the drone. Materials for building an RC drone. 1.four plastic frames. 2.4 brushless DC motor lipo battery rc transmitter rc reciever pcb Steps: 1.Make the frame for the drone where four DC motors will be attached to,also mount the PCB board for connection. Screw the motors to the frame. connect the ECS to the frame. T also connect the RC receiver by following the circuit diagram. Connect the blades. Lastly connect the lipo battery to the PCB. our drone is ready for testing.

How to program an arduino with a smartphone.

H ow to program an arduino with a smartphone Before, we can only program an arduino with a laptop or desktop computer ,but most hobbyist doesn't can't afford to buy one but thanks to the new era of Technology we can now program our board with our smart phone any where we like and at any time.To program an arduino you need to download Arduino droid or arduino commander from the Google play store, I prefer arduino droid to Arduino commander because of it flexibility and ability to understand.To start coding with your phone you need a knowledge of c++ language,the Arduinodroid is both a compiler and an editor that is you can compile your skecth right after writing it. How to program with your smartphone . You will need an OTG cord to connect your Arduino to your phone for skecth uploading since the arduino cord can't directly connect to it.you can only use an android phone with version 2.0 or higher. When trying to upload your sketch the board will feed current from your phon...

How to make a powerbank with 9v battery.

Home made 9v power bank. U  In this article we will learn how to make a power bank for our phones in case of emergency,smartphone has became a very unique device in the life of men but the only problem is the power source to keep it running on.we have many diy power banks we can make like rechargeables,4000mah power bank,non rechargeables,hand driven charger etc.So let's cut our story shot and go straight to the point. Materials. 1.ic7805cv that is for regulating 9v_5v 2.old USB. 3.wires for connection 4.LED,.1k resistor,if you wish to add an indicator bulb. 5.9v battery. Circuit diagram below. good luck!!!!

How to make a wireless phone charger.

DIY wireless phone charger. We all know that wireless power transfer is the transfer of electrical current by means of coils which produce electromagnetic field when electricity is passed through them,wireless power transfer was invented by Nikola tesla in the  1890s by means of his Tesla coil. Working principle of the wireless phone charger. A wireless charger works by electromagnetic induction that is,when alternating DC currents is passed through a transmmiter coil it produces fields and when receiver is c oil is placed near it electrical current is induced into it. For our project we will need the following materials. 1.copper coil 2.2N222A NpN 3.9V or 12v Battery 4.220Ï€ resistor 5.25v 100uf capacitor 6.1N4007 diode. Step1: making the transmitter coil.  make a pancake coil for the transmitter,the pancake coil provide easy transfer of wave than an abituary turns of wire,the transmitter coil should be in about 30-40 turns and connect properly with the circuit diagram below...

Beginner guide to electrical components and description.

Electrical components are commonly found on circuit boards and their presence is ubiquitous in mordern engineering here are some lists of materials you need to be familiar at: 1.Capacitor Symbol of capacitors. It consists of two metals separated by a dielectric material,it is use for storing charges.types: Ceramic, electrolytic,film and vairable capacitors.electrolytic is grouped into aluminum and tantalumcapacitor.Applications range from storing electric charge, stabilizing current, reducing riples in voltage and use in radio for tuning. 2.Diode Diode symbol. It is use for rectifying DC from ac since it only allows current in one direction,the part with white strip is the negative pole known as the cathode while the other black area is the positive side called anode.types of diodes:Zener,LED known as light emmiting diode, photodiodes,avalanche diode. 3.Transistors Transistors. it is basically used for amplification,switching, regulating and control it is made of semiconductors and has...
