Many people have asked me to share some details about my wireless controller for the BMPCC4k. Most questions were about the bluetooth control, so I’ll mention a few details about that. I am assuming you are familiar with the ESP32 Arduino environment. This version of …

In this project we are going to be making something super useful! It is a wireless keyboard that you can connect to your PC and assign each button any shortcut or key sequence you want! I have made it in a way where you can customise the keyboard to meet your exact needs, for example, …

Out of curiosity, I ordered the tiny ESP8266 relay switch from aliexpress.com but never knew it could be so embarrassing to find the right way to operate. The vendor said that the switching program is inbuilt and I only have to use some android phone to operate it. But despite several attempts with several Chinese …
Anyone who’s started learning about microcontrollers and code could tell you that a good place to start is by looking at the most basic example sketches provided. As often times their simplicity can teach you a lot more than you think. With the Arduino, one of my favorite examples is the blink sketch, which is …
Some time ago, I tried to make an “Instructables Hit Counter” using the Instructables API, and an Arduino Uno with a wired network shield. However, with the limited RAM of the Arduino Uno, I was unable to get the system to work. A while ago, I noticed a similar project done by diytronics using a NodeMCU. This was just …

In this post I will attempt to describe the steps I took to build the arduino based thermostat shown in the following videos. The first video was taken when around just half of the coding of the menu system was complete, but gives you a basic run through of the features. This second video shows …
There are lots of Arduino projects to read temperature with different devices, this is an easy one to measure high temperatures with type K thermocouples (1300ºC). Skills necessary for this project are basic (buying max IC already mounted) but I have mount an MAX31855 in a printed circuit (thanks to Antonio an specialist in this). …
This project started as many of mine usually do, as a honey-do. We have compiled an extensive list of our book and movie collections on our computer at home, but my wife wanted to be able to scan the list from the video store (yes, we still go to the video store). So I created …
Using the Mouse library, you can controls a computer’s onscreen cursor with an Arduino Leonardo, Micro, or Due. This particular example uses a five pushbuttons to move the onscreen cursor. Four of the buttons are directional (up, down, left, right) and one is for a left mouse click Cursor movement from the Arduino is always …
