Every Arduino board needs a way to be connected to a power source. The Arduino UNO can be powered from a USB cable coming from your computer or a wall power supply (like this) that is terminated in a barrel jack. In the picture above the USB connection is labeled(1)and the barrel ja...
Furthermore, Arduino’s easy-to-use IDE software for beginners is a more manageable program to learn as it uses a simplified version of C++ compared to other programming software. Because of this, Arduino is commonly cited as the pathway for everyone looking to learn about microcontrollers. With...
This PLC combines the Arduino Mega (ATmega2560) with ESP8266 Wi-Fi module and a 2.4” TFT Touch Screen, in order to make it suitable for Industrial IoT Applications and other factory robotics applications. PLDuino can be easily programmed by using a simple USB cable, also along with the ...
However, if on the same pin an experimental board cable is connected and you simply touch it with your hand, you will notice that the situation is changing from LOW to HIGH and vice versa. To pin is said to float which is not acceptable, especially for such a precise microcontrollers. ...
Figure 2.5 A Typical Arduino Board (Dicimilia) This board has everything starting from ADC to USB controller to PWM ports. So you can now control relays or connect LCD into the digital ports on the top and directly connect the output pin of the sensors to analog ports in the bottom. 5v...
Step Two:Using a USB cable, connect Seeeduino to the PC Step Three:Here is the software aspect of the tutorial. First of all, visit Github to download the example and library code. Step Four:Create a brand new sketch for the Arduino and then paste some codes to it. You can...

For safety, I will have a watchdog that cuts off charging if the Arduino fails for some reason, two temperature sensors where charging will only be done if they "agree" i.e. if one sensor fails, they wouldn't match anymore and the Arduino would see that and r...
Microcontrollers don’t tolerate RS232 voltages and may be damaged. To avoid this,UART(Universal Asynchronous Transmitter Receiver) is used. It sends and receives the data in serial form. To do the level conversion of voltages, RS232 driver IC such as MAX232 is used between the UART and seri...
