This tutorial for beginner raspberry pi user .It is very easy way to install driver for 3.5 inch touchscreen LCD. Before install driver You need A Raspberry pi 3B with raspbian OS because this Lcd screen works with only raspbian OS 1.First Download Txt file from here Save it to your raspberry pi desktop 2.Make sure you have internet connection on your Raspi 3.copy upper part of text from downloaded text file & paste it to terminal emulator Now driver will install & Lcd turn on but HDMI will turn off LCD & touch is working after automatic restart  4.To turn off Lcd & active HDMI ,copy lower part text from Downloaded text file paste it to terminal emulator .Now HDMI will active & Lcd turn off This is full details video for installation driver

In this post I will describe how to make easy clap switch using arduino you can on/off light or fan by clap You need to make it - Arduino UNO Sound sensor module Single channel relay module Some male,female jumper wire Small bread board Ac bulb or Fan                     Connection diagram Connection of relay module with a/c Relay & sound sensor's VCC will connect to Arduino 5 V GND will connect to Arduino GND Soun sensor out pin connect to Arduino pin 6 Relay module's input Pin connect to Arduino pin7 Download code for arduino from here  Watch making video of this project

In this post I want to describe How to connect all parts like brushed motor, throttle brake light, ignition switch via controller It is very easy to wiring e bike parts About Parts you need to make  & all details about electric bi - cycle Click here  You have to use a motor controller ( in my bike I used 24 volt controller) There are lots of wires coming out form the controller .we have to connect those wires to motor,battery,throttle,break ( optional) & ignition switch It is full wiring diagram of ebike Some important  Use 4mm wire to connect battery To use LED as indicator must use a resistor with LED For ignition switch you can use Mofet ignition switch Use good quality parts & wire If you do not have much knowledge about electronics , then take a professional help For details of new version electric bicycle click here
