Using LM35 temperature sensor with Raspberry Pi is a relatively simple task once you have a way to read and convert analog signals. Fortunately in my previous project I’ve shown how to build a basic Raspberry Pi voltmeter with ADS1015 chip. So now we just need to connect the LM35 sensor to one of ADC … Read more
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 is done via I2C . This chip also has an adjustable input gain. This option … Read more
Raspberry Pi based Digital Clock with 16×2 LCD display is a relatively simple project.It requires only a small set of components and can be completed in less than an hour. Previously I’ve published similar designs based on other popular platforms like Arduino and PIC micro-controller. You’ll need a basic 16×2 LCD display with parallel interface … Read more
8×8 LED Matrix chaser based on Arduino MEGA compatible board will be presented in this post. It uses a LED dot matrix display module with two 74HC595 shift register chips connected in serial to control the LED output. Similar design based on MAX7219 LED driver can be found here. For this project only 3 additional … Read more
In this article I’m going to show you how an 8×8 LED Dot Matrix Display can be driven by MAX7219 with Arduino.There are 2 similar designs. PIC16F876 version is available at this link ,for circuit based on 74HC595 click here.For this project I’ve created my own function to send data to MAX7219.This function is called SendDataDotMatrix(). It … Read more
