Nokia 5110 LCD and Arduino – Ultimate Tutorial and Guide

Interfacing Nokia 5110 LCD Display To Arduino In this article, we are publishing a project tutorial which explains different aspects of interfacing a Graphical LCD (GLCD ) Nokia 5110 with Arduino. Nokia 5110 is a  48 x 84 graphic LCD that has an internal controller PCD8544 to control all displays and operations. The Nokia 5110 is interfaced to the microcontroller through a serial bus interface. After going ...

Dash Button Santa with Arduino MKR1000

Send information to Santa Claus about the status of the gift request. Things used in this project Story Introduction How many times have you asked Santa to bring you an Arduino kit, a 3D printer or a set of tools and only brought you a pair of socks? Well, this is going to end. Santa Claus has hired us to run a project based on IoT and Arduino MKR1000, which will help you to have more control over where to ...

ESP8266 + I2S = Software-based 10-Base-T Ethernet Driver

espthernet It's pronounced "e-s-peethernet" - a party trick, not a legitimate engineering solution. ESP8266 + I2S = Software-based 10-Base-T Ethernet Driver For a detailed overview of how this project works, please see the Hackaday article. For a rough idea of what's going on, checkout the youtube video: Overall Discussion This is a relatively unreliable and coincidentally functional ESP8266 Ethernet driver ...

Panelizing and Gerber Generation in Eagle

Story I have been working with Eagle for quite some time but never really got a PCB manufactured. almost all the time i used the toner transfer method to make homebrew PCBs. But then i took a project in which i had to use SMD components and i could no longer use toner transfer method because of the limits on resolution of the Laser printer. Time had come for “properly” designing and generating “Gerber files ...

Stock Monitoring featuring 4Duino-24

In this project, we will use several IR sensors to check if an item from an inventory box is present or not. This project makes use of a 4Duino-24 to check whether an item is present or missing from the inventory. The 4Duino uses its analog pins to read the values from each IR sensor. This reading value changes depending on whether or not the item is present. The 4Duino is set to send most recent status to ...

Improved Arduino Rotary Encoder Reading

Rotary encoders are great input devices for electronics projects - hopefully this Instructable will inspire and help you use one in your next project. Why write rotary encoder code? I wanted to use a low cost rotary encoder as an input mechanism for one of my upcoming projects and was initially bewildered by the code options available to take readings from the rotary encoder and determine how many "detents" ...

Arduino LCD Project for Measuring Distance with Ultrasonic Sensor

In LESSON 18 you learned how to use an ultrasonic sensor to measure distance, and in LESSON 19 you learned how to connect an LCD to the arduino. In this lesson we will combine what you have learned to create a circuit for measuring distance, and displaying results on an LCD display. - See more at: http://www.toptechboy.com/arduino/lesson-20-arduino-lcd-project-for-measuring-distance-with-ultrasonic-sensor/# ...

DIY Soldering Robot Project Completed

The DIY soldering robot which we have been building in our spare time over the past few months is now working and we have been able to solder some test Raspberry Pi expansion board headers with the machine. Before starting on this robot we looked at the various commercial soldering systems that are available.  Wave soldering machines would have been impractical as the connector is on the top side of the boa ...

Arduino Tiny Relay Shield Project

In this Arduino project, you will build a small relay shield from stripboard. The shield can have one or two relays fitted to it. Connect the Arduino and relay shield to your PC via a USB cable. Download the PC software and use it to switch anything on and off that is attached to the relays. The shield is based on the Tiny Stripboard Shield for Arduino project. This video shows the Arduino shield project an ...

Arduino MicroBot Project

Steps On the breadboard, build two bi-directional motor control circuits (also known as "H-bridge") circuits. These circuits will control the two DC motors that drive the wheels. Each circuit will have two wires from the Arduino (one for forward, one for backward) to control the circuit, and two wires from the single DC motor that it is controlling. You should test your circuits to ensure you can control bo ...

New Arduino Project: Spectrum Analyzer?

I've been reading a lot about receivers, and it sounds like one important thing is filtering. It makes sense too - simple receivers can suffer from front end overload due to a strong signal.  And when on the ham bands, you never know where that strong signal may be - it could be someone driving down the road (which is a bit obvious once you see it), but in my neighborhood, if you don't know me, you're proba ...

Rain Alarm Project

Water is basic need in every one’s life. Saving and proper usage of water is very important. Here is an easy project which will give the alarm when there is rain, so that we can make some actions and save the rain water. As a result, we can increase the water levels of underground water by using underwater recharge technique. Rain water detector will detect the rain and make an alert; rain water detector is ...
