In this project, we create a joystick-controlled laser by connecting two servos to a joystick and using ... can have a value only between 0 and 1,023 when read by the analog pin of the Arduino.

he made a breakout board for 32-channel analog multiplexer device he wants to use. He put the project out on Hackaday.io and also has a video tutorial you can see below. There are five input pins ...

Among all the Arduino ... these pins can send varying output voltages to a component (e.g., 25%, 75%, 33%) instead of the usual 100% or 0. This variable output is achieved with the use of a ...

You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Here, the three LEDs are directly connected to Arduino pins with independent ... With the help of ...

Reading the temperature of your environment is pretty easy right? A quick search suggests the utterly ubiquitous DHT11, which speaks a well documented protocol and has libraries for every ...

Arduino boards can most definitely help ... As for the pins, the UNO features 14 digital pins for both input and output use, six analog pins for input only, three ground (GND) pins, a VIN pin ...

You need a connection before you can ... we define which three pins we want to use for red, yellow, and green on the Arduino. Instead of using defines, we assign the pin values each to a global ...
