In this tutorial, we will build a circuit with Arduino Uno that can read voltages from 0 to 30V DC and display them on the 16×2 display, the ideal project to build our DIY voltmeter. Thanks to the analogue inputs, that can be used to measure voltages from 0 to 5V. For higher values ​​we…
In this project, we will build an infrared remote-controlled car so that it can be controlled with any type of infrared remote control. By modifying the design of the robot avoids obstacles we will insert an infrared receiver TSOP4838 or VS1838B or a TSOP 1738 (they only change the pin configuration) instead of the ultrasonic sensor….
How many times have we wished to have a robot that goes around the house avoiding obstacles? Creating this project with Arduino Uno, an HC-SR04 module and two wheels will take us to be a child. The robot is able to avoid obstacles, thanks to the ultrasonic range finder sensor that senses obstacle coming on…
This is yet another ultrasonic range finder project using Arduino. We have done several similar projects in the past. It allows us to control a buzzer based on the distance detected by an HC-SR04 sensor, making it sound with a frequency proportional to the distance from an obstacle.
In this tutorial, we will learn how to move a servo through the values ​​sent by a flex sensor. We can therefore take a step forward in creating robotic joints, such as moving arm hands and many other things.
This is the second time I am writing an article on how to use the fully assembled clap switch that I designed in 2014. This time, I have put several images and written explanation on each of the images so that you can use it easily. At the end of the photo gallery, you can…
