Hi guys. In this instructable, I will teach you how to build an obstacle avoiding robot. The robot will be a small and simple 2-wheeled car which will move forward until it detects an obstacle in its path. Upon doing so, it will stop, move a little back and then look towards its left and […]
This instructable will show how to monitor EC, pH, and temperature of a hydroponics setup and upload the data to IBM’s Watson service.Watson is free to get started with. There are paid plans, but the free plan is more than enough for this project. Step 1: Things You’ll Need Any ESP32 development board. This one seems reasonable, […]
For this Instructable, I have made a primitive musical soundboard using an ultra sensor as a keyboard. Here I will show you the basic steps on how to create such a device yourself. Later on, in December, I will demonstrate to you how to make a more complex or soldered version of this soundboard with […]
Temperature and humidity measurement are always a nice addition to hobbyist projects. In my previous post, I’ve discussed the DHT11 sensor, which is capable of measuring both temperature and humidity. They are digital sensor and provide calibrated outputs with temperature and relative humidity. I’ve also demonstrated how to interface with Arduino and display it on […]
Web site: http://www.instructables.com/id/Human-Body-Infrared-Smoke-Temperature-Alarm-System/ Project Summary: The Human Body Infrared Smoke Temperature Alarm System works under the DC 5v voltage and uses the DH11 Temperature Module to detect the room temperature. When the module detects the temperature is higher than the maximum, the buzzer alarms and the red LED lights. When the MQ2 Smoke Sensor detects […]
The goal of the project is to come up with an affordable yet generic vibrotactile feedback device to be used for educational purposes. A chemistry learning environment is developed to demonstrate a specific application of our device, in which users can manipulate ions and feel the corresponding electromagnetic attraction and repulsion forces through the vibration […]
IoT based Patient Monitoring System using ESP8266 and Arduino Health monitoring is the major problem in today’s world. Due to lack of proper health monitoring, patient suffer from serious health issues. There are lots of IoT devices now days to monitor the health of patient over internet. Health experts are also taking advantage of these […]
In this article, we are presenting a tutorial on how to interface LM35 and Arduino along with its program. Once we successfully interface arduino and lm35, we will go on to build a temperature display using arduino and a 16×2 LCD module which constantly monitors temperature around the measurement field/range of LM35 and displays the […]
This is arduino based collision detection warning system. This kind of system is fastest growing safety feature in automotive industries. Such system enables vehicles to identify the chances of collision and give visual and audio warning to driver. So that driver can take necessary action to avoid collision. This project idea is based on arduino […]
This Arduino project is a simple and fun project you can build in 10-15 minutes. The result of this make will be an Arduino audio player that plays “.wav” files. It consists of a speaker, a simple transistor acting as an amplifier, and a micro-SD card adapter with a micro-SD card in it where the .wav […]
