1. Battery Voltage Level Indicator on LED Bargraph
This Arduino battery voltage indicator indicates the status of the battery by glowing LEDs on a 10 Segment LED Bar Graph according to the battery voltage. It also shows your battery voltage on the LCD connected to the Arduino.
2. TVOC and CO2 Measurement using CCS811
For designing an air quality monitoring system we need durable and reliable air quality sensor. Although there are many Air Quality parameters but the most important are CO2 and TVOC. So for sensing CO2 and TVOC, we are using CCS811 Air Quality Sensor.
3. Automatic Pet Feeder Project
This Arduino based Automatic Pet Feeder which can automatically serve food to your pet timely. It has a DS3231 RTC (Real Time Clock) Module, which used to set time and date on which your pet should be given food. So, by setting up the time according to your pet’s eating schedule, the device drop or fill the food bowl automatically.
4. DIY Inclinometer
The MPU6050 is an IC 3-axis accelerometer and a 3-axis gyroscope combined into one unit. It also houses a temperature sensor and a DCM to perform a complex task. The MPU6050 is commonly used in building Drone and other remote robots like a self-balancing robot. In this project we will learn how to use the MPU6050 is built an Inclinometer or Spirit Leveller. As we know an inclinometer is used to check if a surface is perfectly leveled or not, they are available either as sprit bubble ones or as digital meters. In this project, we are going to build a Digital Inclinometer which can be monitored using an Android application. The reason for using a remote display like a mobile phone is that we can monitor the values from MPU6050 without having to look at the hardware, this would come very handy when the MPU6050 is placed on a drone or some other inaccessible locations.
5. Alcohol Detector using Arduino
This Arduino Alcohol Detectorwill detect the alcohol level in breath and by using some calculations in code we can calculate the alcohol level in breath or blood and can trigger some alarm.
I wanted to thank you for this excellent read!! I definitely loved every little bit of it. I have you bookmarked your site to check out the new stuff you post. sure feed feeders
