Electronics explained in a simple way
An H-bridge is a simple circuit that lets you control a DC motor to go backward or forward.
You normally use it with a microcontroller, such as an Arduino, to control motors.
When you can control two motors to go either forward or backward – you can build yourself a robot!
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 build a CNC mill.
But such a machine is a bit complex, so we decided to discard that for now.
Then Eduardo suggested building a sumo robot.

It was sunny and hot.
I was wearing a backpack and I could feel the sweat building up on my back.
But I had to walk fast.
Because I was late.
And because the locals had told me to be careful in the center.
I had emailed with Thomas, the founder of the makerspace Göra, before coming here.
We had discussed electronics workshops but decided that it would be better to meet in person to figure out the details.
I did not know what to expect.
Across the street, I saw it.
I went to Sweden back in October to create a new course for Ohmify (https://ohmify.com/join). I was so focused on the course that I forgot to make videos explaining what I was doing. Anyway, this was very fun to do so I will try to make more – and better! – videos in the future.

As some of you know, I’ve been into mini-radars for a long time.
Not sure what a mini-radar can do?
Check out some of my radar circuit examples.
On my GitHub repository, I’vGitHub hosting an Arduino library for the XeThru Radar Sensors.
Novelda, the company behind the XeThru radar, has created their own GitHub repository now, so I’ve moved the code there and made some updates.
