Looking for a simple circuit to control the light intensity ... we can use the low voltage output from the Arduino ports to control high voltage/current loads -the popular “12V LED strips”- for ...

In this project, we are going to make a LED Binary Clock Using Arduino. Here we have designed a printed circuit board (PCB) to implement this clock. To design PCB layout, we have used EasyEDA online ...

Circuit Diagram and Working Explanation . Here we are going to write a program to blink an LED for every 500ms. In arduino uno, a LED will be already designed at the pin13, but we are not going to use ...

1: Circuit diagram of the 7×5 LED matrix using Arduino The circuit shown in Fig ... For initial testing of Arduino board, upload a simple program like Blink from the example sketches in Arduino IDE.

or Arduino Nano 33 BLE Sense, Portenta H7 board. You can use a generic BLE central app, like LightBlue (iOS and Android) or nRF Connect (Android), to interact with the services and characteristics ...

The RGB LED examples are constructed in a similar fashion to the various tutorials below. The circuit diagrams are shown below for each example. Note each example here is using a Common Anode RGB LED.

In my example the whole circuitry is powered from a 9V battery and I use a small 12V fan, but you should use a 9V or 6V. If you want to use higher currents then replace the BC547 (100mA maximum ...

Fig. 2: Circuit diagram for interfacing laser LED module with Arduino. Connect pins 7 and Gnd of Arduino to pins 1 and 3 of KY-008 module, respectively. Run the first sketch (onoff.ino) to turn the ...

For example, you could make a LED memory game ... connect the game circuit to the Arduino board and upload the code; then play your game and have fun! Develop educational games that incorporate ...
