Car Reverse Parking Sensor Circuit with Alarm
In this post I will show how to construct a car reverse parking sensor alarm circuit using arduino, ultrasonic sensor and 2.4 GHz transceiver module. This project can be add-on feature for your car if it doesn’t sport a build-in parking sensors. Introduction The proposed project has similar functionality as traditional car parking sensor has, […]
Introduction to RGB Colour sensor TCS3200
TCS3200 is a color light-to-frequency converter chip which can be programmed through a microcontroller. The module can be used for detecting all the 7 colors of white light with the aid of an integrated microcontroller such as Arduino. In this post we are going to take a look at RGB color sensor TCS3200, we will […]
7 Best Touch Sensor Switch Circuits Explored
In this post I have explained 8 easy methods of building touch sensor switch circuits at home, which can be used for switching 220 V appliances ON/OFF with mere finger touch operat ions. The first one is a simple touch sensor switch using a single IC 4017, the second one employs a Schmidt trigger IC, […]
DHT11 Humidity, Temperature Sensor: How to Use and Interface with Arduino
We are now going to talk about one small cheap sensor that we call DHT11, and we can use that for measuring humidity and also temperature. You can see that many Arduino people like this sensor because it is very simple and also very low cost, so anybody can buy and try. The DHT11 can […]
ACS712 Current Sensor Circuit Diagrams and Datasheet
Here we are going to learn one cool and very important current sensor device which we call ACS712. This small chip that look just like a normal 8-pin IC, is actually able to sense current from any load and give us a proportional analog voltage output which we can easily feed to Arduino or any […]
