Digital Clock with LCD Shield Board for Arduino

Digital-Clock-with-1602-LCD-Shield-Board-for-Arduino-Featured-Image

Arduino clock can be implemented by using LCD Shield Board for Arduino. This shield can simplify the prototyping process of many Arduino based circuits. It incorporates a 16×2 display and a basic 6 buttons keypad thus removing the need for additional wires and connections. All buttons are connected to A0 analog input through a resistor … Read more

Binary to Hex 7-Segment Arduino

Binary-to-Hex-7-Segment-Arduino-Featured-Image

In this post I’ll show you how to build a simple Binary to Hexadecimal converter using common cathode 7-Segment display and Arduino Mega compatible Iduino Mega R3 board.  Similar devices should also work ,however I did not test it. The circuit has 4 binary inputs (Input Bit 0 – 3) and 7 outputs,  one I/O … Read more

Arduino based LCD Bargraph Voltmeter can be easily assembled with Arduino Mega 2560/Arduino Uno or compatible boards. Arduino LED battery level indicator is here. Similar design based on Raspberry Pi platform is available at this link. This design is basically the same circuit I’ve shown in Bargraph Voltmeter except for  2 main differences. Current design … Read more

LED Blinking STM32L011K4

LED-Blinking-STM32L011K4-Featured-Image

All my previous project were based on PIC microcontrollers or Arduino board, however recently I’ve been experimenting with STM32 MCU. For this simple project a NUCLEO board based on STM32L011K4 MCU was used. The STM32 Nucleo-32 board provides a simple way to try out new concepts and build prototypes with the STM32 microcontroller. You can … Read more
