HC-SR04 Ultrasonic Sensor with Arduino

To detect objects at a distance in your Arduino projects, the HC-SR04 ultrasonic sensor is a common option. It comes as a board that’s easy to integrate in your projects, and it can be bought for pretty cheap. To learn more about this sensor I built a quick project on a breadboard to test it…

Building the Geekcreit® DIY L298N Autonomous Robot Car

A few weeks ago while I was shopping on Banggood for new parts I wanted to try out, I came across this great robot kit from Geekcreit. The Geekcreit® L298N 2WD Motor Ultrasonic Robot Car Kit (Banggood) is based on an Arduino board and includes many parts I was looking to purchase separately such as:…

Buying Electronics Parts Online Cheaply

When I first got started in electronics, just getting started was a lot more expensive. Just programming a chip would require a 50$+ dollar USB programmer, and Arduino was still a very new project. A few years after this I heard about eBay as a source of cheap parts, and everything had changed! You could…

Connecting i2c devices to your Arduino

The i2C protocol is one of the most popular way to communicate with sensors and devices with an Arduino. This protocol was built to limit the pins needed and to standardize the communication so you don’t have to figure out a proprietary format each time. A i2C devices only takes two pins of the Arduino…

Arduino vs Raspberry Pi : Which one should you pick?

The Arduino platform is based on a microcontroller, while the Raspberry Pi is a single board computer. They both have a very large community and may look similar on the surface, but they are very different to work with. Unless you’re really hardcore and want to build a complete circuit board from scratch before even…
