Arduino Up Down Counter LCD
Up Down Counter design based on Arduino MEGA compatible board is the topic of this article.it uses 2x16 LCD display to show the counter values and 4x3 keypad to input initial 3 digit number.The counter will count Up/Down according to ...
LCD Voltmeter based on Arduino
This post is about building a simple 0-5V 3 digit voltmeter using Arduino UNO compatible board and 4x20 LCD display. This design should also work on all similar boards, I’ve tested it on Arduino Mega and UNO boards. No additional ...
Binary to Hex 7-Segment Arduino
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 ...
PIC C Programming
In this article I’ll show you how to program Microchip PIC microcontrollers using HI-TECH PICC compiler and basic PIC development board. The board consists of PIC16F876A, LED bar graph and 20MHz oscillator. PICKIT3 compatible programmer was used to download the ...
1Hz Clock Generator using PIC16F876
In this article we’ll see how to generate 1 Hz clock with PIC16F876/877 PIC microcontrollers. 3 different approaches will be demonstrated. The most basic solution is to use nested loops to “waste” enough instruction cycle time in order to produce ...
Digital Clock with LCD Shield Board for Arduino
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 16x2 display and a basic 6 buttons keypad thus removing the need for ...
Fading LED with PCF8591 Arduino I2C
Controlling LED brightness with Arduino is one of the basic circuits you can built. Fade sketch is even included in the basic examples in the Arduino IDE. However on Arduino boards it’s done by pulse width modulation, changing the duty ...
LCD voltmeter based on ADS1015 with Raspberry Pi
LCD voltmeter with Raspberry Pi and ADS1015 is the topic of this project. Similar design for Arduino platform is available at this link. ADS1015 is a 12 bit ADC chip with 4 analog input channels. The interface with Raspberry Pi ...
Fading LED with PIC microcontroller
This article shows how to create a fading/dimming effect of the LED using PIC micro-controller. For similar design based on Arduino click this link.Controlling LED brightness using PWM is a relatively simple task and can be accomplished by configuring PIC16F877 ...
7-Segment Display with SPI PIC16F876A
For this project two PIC16F877 MCU's were used, see project schematics below. Slave PIC runs LEDs decoding and multiplexing code on data received from Master. 7-Segment inputs connected to PORTC,B and common digits anodes to PORTB,A via 2N3906 collectors for ...
