Arduino Interface Here is an illustration of simple angle sensing for flex resistor. If the flex resistor is flat, blue LED illuminates, if the resistor is flexed to an angle x (say) green LED illuminates, if it flexes greater than x then, red LED illuminates. Flex resistors can be also...
The microcontroller itself (theATmega 328P) is a tiny chip plugged into the Arduino board, and the Arduino board provides a beginner-friendly interface with a USB port, pin headers, DC power jack, among other things to help you program or connect things to it more easily. I encourage you...
First off, we'll use the Arduino's digital pin 8 to send a signal to the relay, through the other components. So hook up the pin 8 to a 1 kohm resistor. Why the resistor, because the transistor I'm using that will catch the signal from the pin no. 8 can't handle the full 5v...
To control high-voltage or high-power circuits with an Arduino, you have to isolate them from the Arduino with a relay. Here's how! To control high-voltage or high-power circuits with an Arduino, you have to isolate them from the Arduino with a relay. Here's how! Circuits that operate...
The Arduino can be programmed to turn on the relay when a certain event occurs, for example when the temperature of a thermistor gets higher than 30°C. Or when the resistance of aphotoresistordrops below 400 Ohms. Almost any sensor can be used to trigger the relay to turn on or off....

I'm going to show you how to emulate an Xbox controller with an Arduino, using a USB capable microcontroller and the ArduinoXInput library.
The physical hardware of Arduino is the board itself. However, when it comes to Arduino boards, there are multiple varieties with different functionalities. Today we will be looking at ourSeeeduino V4.2, which has the same functions as one of the most popular Arduino boards – the Arduino UNO...

Both these built-in modules help you to design advanced projects and control the peripherals wirelessly. Similarly, you can connect ESP32 with an Android phone and...
The output pin that activates the relay is defined on line 7: int signalPin = 12; After connecting everything to the Arduino, you should have something that looks like this: Well that’s about it. It’s not hard to set up a keypad at all. I think with a little trial and error yo...
