The Arduino board will give us an analog value between 0 and 1023 on the A0 pin. When there is no light, the analog value will be lower, and when the intensity of light is higher, the analog value will be higher. We have set a threshold value in the code, which is 500. So, whe...
shield: a printed circuit board (PCB) that adds functionality to your Arduino Hardware: A circuit is pre-wired and sold on a printed circuit board Software: A software library is provided to interact with the hardware Benefits of Shields No wiring needed Circuit is pre-wired Connections to Ard...
Turns out a fair number of people using the TM1638 have stumbled on such issues when using higher-speed devices with Arduino libraries. It's been ascribed to voltages (though the board actually works fine with 3.3V or 5V as long as the I/O is properly level-shifted), "bad boards" and...
for display purpose. So different people use different controller but here we shell the user how interface this display with Arduino board. First of all, one thing should be keep in mind some of the displays has swapped ground (GND) and VCC pin therefore the user should be make sure before...

an illuminated LED. By adding a liquid crystal display (LCD) to your Arduino, you can more easily display complex information (sensor values, timing information, settings, progress bars, etc.) directly on your Arduino project without having to interface with the serial monitor through the ...
ESP32 interfacing with DC Motor DC Motor Control using ESP32 and Arduino IDE Here, we are going to change the rotational direction of the DC motor using ESP32. Here, to change the direction of the motor here we have used the web server. ...
Below you see one example of driving a relay circuit using a transistor. You can drive the transistor using an ESP32 or an Arduino UNO GPIO pin to turn the relay ON or OFF. Source:https://www.electronics-tutorials.ws/blog/relay-switch-circuit.html ...
