This is a simple motion sensor project using Arduino. A 220V AC lamp is connected to a 5V relay and the relay is activated once the motion sensor senses motion and sends a signal to the Arduino. List of materials Arduino Uno (Â Rev 3Â ) Sensor (Â PIRÂ )Â Â HC-SR501 Keyes SRD-05VDC-SL-C Relay Module or any 5V relay module…
It is just another ‘build your own Arduino’ project. BuildCircuit has worked on similar projects before. The most popular project is a DIY Arduino kit. The DIY Arduino looks similar to the real Arduino boards and uses an FTDI basic programmer to program the chips. The kit that we are going to work on this…
Description: Here’s a simple DIY clap switch circuit. The circuit is mainly composed of an audio frequency and a bistable trigger circuit. Q1 and Q2 together form an amplifier circuit. MK1 (electret microphone) accepts Clap/Audio signal and that enters to transistor Q1 through the coupling capacitor C1 and enters to Q2 base through collector directly after getting…
About FTDI FT232RL breakout board:Â This tutorial is about making Arduino on breadboard using a basic FTDI FT232RL based breakout board.The pinout of this breakout board matches the FTDI cable to work with official Arduino and cloned 5V Arduino boards. It can also be used for general serial applications. The major difference with this board is…
