This project measures water level with water sensor module and displays it on seven-segment display. If the water level is less than 600 the green light will turn on , otherwise the red light will turn on and the buzzer will sound.
TFT low frequency oscilloscope, bandwidth is DC to 2000Hz. Max sampling rate is 40000 samples per second. An oscilloscope with these specifications has limited use, but it is a good exercise in using LCD TFT. Arduino can be Uno or Nano. The...

Hi all of you. in this project I can use 4 seven segment with 4 74HC595 multiplexer IC. my project wiring is shown below picture. in each time I show a number in left seven segment and then shift it to next seven segment in right side. I repeat...
Hello everyone, I want to share my first project using the ESP32. In the project, I'm using an ESP32 to control the L298, which drives two 12V, 120 RPM motors. The pins used are: D13, D12, D14, D27: Control the L298. D23: Controls the PWM for...
After a relatively long absence, I decided to enter the world of robots. To begin with, the first robot I made is a warrior robot. After turning on the device, the robot turns around to find an object at a distance of less than 50 cm. This is...
