Arduino Liquid Crystal Displays
A tutorial on LCD communication was planned for a later date due to high demand. A circuit was already assembled for testing a new LCD provided by element14. The tutorial explains how communication functions with modern LCD character displays, showcasing...
Arduino FM radio receiver shield
This guide will demonstrate how to construct a custom FM radio receiver shield compatible with an Arduino board. The radio chip utilized in this project is the AR1010, which can be sourced from Sparkfun or Electrokit. Code for initializing the...
What kind of transistor do I need to amplify an Arduinos PWM outputs
Control 30 incandescent light bulbs with an Arduino Uno on three channels (10 bulbs per channel in parallel). Previous experience involved using an Arduino to control red, green, and blue LEDs with a simple schematic that included three transistors. However,...
Gray Projects
After learning to operate the device, it became evident that inertia posed a significant challenge. The constructed system is notably heavy, making it difficult to initiate motor operation at full speed. Despite having some understanding of physics, practical experience is...
Arduino UNO Tutorial NightLight
A Light Dependent Resistor (LDR) is utilized to create a simple nightlight for children's bedrooms that automatically turns on in darkness and off in light. The resistance of an LDR varies based on the light intensity it receives. In this...
Arduino Thermostat
This is a brief update regarding a project that is currently incomplete. The thermostat for the central heating system in the house has become unreliable recently. A new unit from the heater's manufacturer was quoted at $450 AUD, prompting the...
learning Arduino programming
The circuit consists of a 10 kΩ resistor, a 470 kΩ resistor, a potentiometer, and an LED. This circuit is intended for learning Arduino programming in class.
The circuit utilizes a combination of resistors and an LED to create a...
Water Flow Gauge using Arduino
Measuring the consumption of a resource that has units by volume can be more challenging than it appears. Resources such as water, gas, and electricity are typically measured using gauges that determine either the instantaneous flow rate or the cumulative...
Arduino-Board
When starting with Arduino, one often accumulates more Arduino boards than RS232 or USB ports available on the computer. Therefore, it is more practical to use an external signal level converter rather than placing it directly on the Arduino board....
