DS3231 RTC with TFT display and DF-Player to make the cuckoo sound. Every 15 minutes it sounds once and on the hour it sounds the hour. The RTC is 2 ppm accuracy so you are going to miss your next birthday by about a minute. The code in C is for...
Hello, My latest project... maybe looking at the project diagram I attached, it seems complicated... yes it is... but it works! For a version with free code see link below https://www.b4x.com/android/forum/threads/home-control-4.148024/
Hi all of you. This project is a Clock that can set current time and wake up time. We can select mode with one push button.(clock setting mode or wake up setting mode) and can change in with two push button. one of that for hour and another for...
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...
USB thermometer using DS18B20 as a temperature sensor. The temperature can be displayed in Chrome, Edge and Opera browsers https://developer.chrome.com/en/articles/serial/#browser-support . Run the Arduino connected to PC, open file...
Hi This system in include 2 part. part 1 is a ultrasonic radar system include one ultrasonic module and one servo motor. This system detects targets at a distance of less than 4 meters. part 2 is a rocket platform with 3 rocket. when radar...
Hello. Back to active here on the forum. I made a simple project to learn about Arduino (B4R) and also about XInput on B4J, to use controls on PC, xbox etc... this design uses 4 servo motors to pull the suspended platform. thx
Arduino Uno or Nano generates 244-8,000,000 Hz by dividing the 16 MHz crystal oscillator. The pushbuttons set the division from 255 Hz to 8 MHz, holding the button advance the frequency every second.. The high frequency output at pin 9 is 8000000...
A very simple ESP8266 project created by B4R with Relay & ESP8266Ping Library.
Logic analyzer 4 channels for frequencies up to 20KHz. Arduino Uno or Nano use the B4A app to display the logic. Waveforms aren't accurate for frequencies over 20KHz due to the low speed of the microcontroller. The code sends 64 bytes of input...
My project is related to carbon monoxide warning system. The tools I used in this project are: Arduino Nano TM 1637 board, 5V buzzer, bread board, male to male jumper wire, green and red LEDs. The way this system works is that if the level of...
