Introduction Over the past few tutorials, we have mentioned several scenarios where using any of the Arduino board in a project may be an overkill due to the cost, size, and more technical reasons such as high power consumption. In the last tutorial, we discussed an alternative way of...

Introduction Cost and size, just to mention a few, makes using an Arduino board in certain projects an overkill, often times its always too big, or too expensive for the scope of the project especially when it's a project that we need to make several units. One good way to retain...

Smartphone’s camera detects your face and the fan moves automatically according to your face. This is an easy project using obniz, servo motor, smartphone, and a fan. Required Components Obniz Servo motor Small USB fan USB <-> Pin header Pin header...

Over the past few tutorials, we explored several ways to further reduce the power consumption for Arduino based projects so they can last for a long period of time running on the inexpensive AAA batteries. We have tried different approaches like the more recent tutorial on using...

Project Summary You can measure room temperature and control your AC from outside with your smartphone. Let's create DIY air conditioner remote controller with obniz. Things used in this project Obniz IR module LM32DZ Smartphone Step 1 – setting up obniz To...

While building Arduino or any other microcontroller platform project over time the need will arise to establish communication between two of the Arduino boards or microcontrollers for data exchange and/or control. This communication could be achieved using either wired or wireless...

Introduction One of the downsides of using an Arduino board in projects is the fact that it comes with some other components which may not be needed after the code has been uploaded to the board. These peripherals consume a considerable amount of power which affects the overall power...

Screen technologies have evolved over the years since the cathode ray tube was first demonstrated in 1897, we have moved from plasma to LCDs, followed by LEDs, OLEDs, and more recently e-paper which is what we will look into today. Electronic paper/e-paper displays are display devices...
