In this short tutorial, you will learn how to build an Arduino Theremin. You only need three components plus the Arduino, wires, and breadboard. Use the breadboard diagram or the video below to see how to connect everything.
Arduino is an easy-to-use development board for hobbyists, tinkerers, and professionals. To build prototypes, for instance.
It's probably the easiest way to learn microcontrollers these days. Therefore, many use it as a tool to teach kids about coding and electronics.
You can build projects like a robot or an automatic cat door. Even if you have no experience from before.
On this page, you'll find a library of tutorials, projects, and other resources to help you get started and build cool Arduino projects on your own.
Thomas was right. It was impossible to get anyone to do anything in December in Medellin. So I continued on my own. There was one challenge left before I could assemble it all and program the robot: The ultrasonic sensor. I hadn’t tested it yet, so I had no idea how well it would work.
This week we got a new member. So we revised what we’ve done so far with our new member: The first week we looked at different robot platforms. We wanted to be able to go forward, backward, and make turns. And we wanted it as cheap as possible. We looked at different platforms at the […]
We made progress on our robot this week! Check out the video at the end of this post. This is what happened: During this week I figured out that our H-bridge circuit did not work as intended. The problem was the TIP12x transistors. They have a huge voltage drop from collector to emitter of 2V. […]
Today we tried to build an H-bridge to control the motors. An H-bridge is a circuit that makes it easy to control a motor to go backward or forward, for example from an Arduino. We used TIP120 and TIP127 transistors and built the following circuit using 5V as VCC:
We started out as a group of three people. Eduardo, Jefferson, and me. Today, we discussed what to build. We wanted to build something that would be fun, and that we could finish within the time frame I’m going to stay here (~2 months). And it should be based on an Arduino. Jefferson wanted to […]
