This is a small project created to display temperatures and humidities. The system uses Arduino Uno, DHT11 temperature sensor, LCD screen, switch and a potentiometer. In the device there are two views ...

This is my code for a personal project. I have created a metronome using an Arduino Uno kit that displays the BPM (beats per minute) on a LCD screen, which can be adjusted using a potentiometer.

The V0 (also labelled as VEE) connection is for contrast control, and a potentiometer (10K) is usually attached to this terminal. Normally, the R/W terminal is tied to ground. For backlighting purpsoe ...

Rotate the potentiometer knob forward and backwards to adjust the LCD contrast. RS Selects command register when low, and data register when high. Read/write Low to write to the register; ...

Although keyboard and soft-pushbutton panel control are increasingly popular, many applications need distinct potentiometers and switches. The SW44175 device from Electro-Mech combines a backlit ...

For detailed explanation, you can check how to use LCD with Arduino. Display the LED Brightness on a 16×2 LCD. The combination of an LCD and Arduino yields several projects, the most simple one being ...

STM32 SPI Programming. The programming is similar to the Arduino code. The same <SPI.h> library is used in programming STM32F103C8. It can be programmed using USB port without using FTDI programmer, ...
