Simple Microcontroller 5V DC Regulated Power Supply

In any electronic products or projects there is always a source of power for the system to work. This is called a power supply. The source of this power can come from different sources like the mains AC voltage, a battery or even from a renewable power source like a solar panel wind turbine or fuel cell to name just a few. The most common source of power is usually the mains AC, with this power, we need a transformer to [...]

Digital Thermometer using Arduino and LM35 Temperature Sensor

Temperature sensors are very important in many projects especially in temperature logging devices and alarms. In this article we are going to design a digital thermometer using Arduino Uno. This digital thermometer is built around the LM35 which is a precision integrated-circuit temperature sensor whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. Its output changes by 10 mV per °C so there is no need for calibration. It can measure a wide range of temperature from −55 [...]

Breadboard Regulated Power Supply 5V/3.3V

In any electronic product or project there is always a need for a source of power for the system to work. This is called a power supply. To get power hassle-free to the power lines of a breadboard can be a challenge, you will need a convenient and safe way to get either a regulated 5V DC or 3.3V DC depending on your application  on your breadboard power rails. In this project we are going to design step by step a [...]

Arduino Shield Tutorial – Make Your Own Relay Shield

Arduino shields are boards that can be plugged on top of the Arduino PCB to extend its capabilities. This makes prototyping with Arduino plug and play. Instead of soldering or wiring external devices or sensors, you can simply hook your board with a shield. This speeds up development time even for absolute beginners. This is a practical tutorial, we’re gonna build a fully working complete Arduino Relay shield, we’re gonna go through all the steps

Arduino Shield Tutorial – Make Your Own LCD Keypad Shield

Arduino shields are boards that can be plugged on top of the Arduino PCB to extend its capabilities. This makes prototyping with Arduino plug and play. Instead of soldering or wiring external devices or sensors, you can simply hook your board with a shield. This is another practical tutorial, we’re gonna build a fully working complete Arduino LCD Keypad shield, we’re gonna go through all the steps, we’ll start from scratch explaining and simulating the circuit diagram in Proteus, then [...]
