Are you interested in learning the details of a BMW? Better still, you can learn all the options the vehicle is equipped with. Thanks to VIN online decoders like BMW VIN decoder you can learn all about a BMW through its VIN. In this post, you will learn how to …

Have you read the MAX30100 tutorial and are still having trouble making that chip work? Maybe it’s time to use another Arduino heart rate sensor. The MAX30102 module has a better hardware design and software support. I’ll explain why after the jump.

Now that we have set up the Raspberry Pi Pico for the Arduino environment, it’s time to build real projects. First on the list is a simple motion detector using a Passive Infrared Receiver (PIR) sensor.

In my previous post, I showed how challenging it was to build code for the Raspberry Pi Pico in C/C++. Fortunately, the microcontroller is now fully supported by the Arduino IDE! This post shows you how to program the Raspberry Pi Pico as if it’s an Arduino.

If you are searching for a place to live, you’ll soon be faced with the “fun” task of reading & understanding your lease. This legally enforceable contract spells out your down payment, termination date, responsibilities as a tenant, and the rent you’ll be paying every month.  Although it’s a lengthy …

Online dating has become the new ordinary. If you are searching for Mr. or Mrs. Right on different dating applications, it’s critical to find ways to ensure your security. There are numerous instruments available to you between ride-sharing, auxiliary email accounts, and a subsequent telephone number. Continuously ensure that you …

Launching a project into production doesn’t mean it’s 100% finished — this is why software/firmware updates exist. And your users are not programmers so you want the update process as user-friendly as possible. Thankfully, the ESP32 allows you to update its compiled code, called firmware, to be updated over the …

The Arduino was invented primarily for non-engineers but now, a lot of engineers are also into it. Using it in a fully-developed project is not a good look, yes, but it’s a lot quicker than building from scratch.  My only issue at the beginning is finding the best way to …

A few months after its release, I finally got a hand on the Raspberry Pi Pico. It’s a microcontroller board featuring the RP2040, but don’t expect it to be like an Arduino UNO. 

We continue with our series on the 8051 with a tutorial on serial transmission. Data communications via the serial port is an easy way for a microcontroller to ‘talk’ with the outside world. Examples of devices that have serial interfaces are sensors, LCDs, EEPROM, SD cards, and RTCs.
