Review: Mayhew Labs "Go Between" Arduino ShieldHello Readers In this review we examine an interesting, fun and possibly a prankster’s delight – the “Defusable Clock Kit” from nootropic design. The purpose of this kit is to construct a clock...
Review – nootropic design defusable clock kitHello Readers Time for a follow-up to the Single Button Combination Lock by creating another oddball type of switch/lock. To activate this switch we make use of a Parallax Ping))) Ultrasonic sensor...
Project – Ultrasonic Combination SwitchHello Readers Recently the Arduino team have released version 1.0 of the IDE (integrated development environment) that we all know and love. This is a significant milestone as the IDE has previously...
Initial Review – Arduino v1.0 IDEWelcome back Whilst being a passenger in a vehicle with a ‘reversing sensors’, I became somewhat curious as to how the sensors operated and how we can make use of them. So for this chapter we will...
Tutorial – Parallax Ping))) Ultrasonic SensorWelcome back In the last few weeks an article about how to use either an Atmel ATtiny45 or ATtiny85 microcontroller with Arduino software took my interest. The team at the High-Low Tech Group at MIT...
Using an ATtiny as an ArduinoWelcome back fellow arduidans! This is the second part of our numeric keypad tutorial – in which we use the larger keypads with four rows of four buttons. For example: Again, the keypad looks like...
Tutorial: Arduino and Numeric Keypads – Part TwoWelcome back! In this article we are going to revisit the I/O pins, and use what is called “Port Manipulation” to control them in a much faster manner than using digitalWrite(). Why? Speed! Using...
Tutorial: Arduino Port ManipulationWelcome back fellow arduidans! This will be the first of two chapters that will examine another useful form of input – the numeric keypad; and some applications that hopefully may be of use. Here...
Tutorial: Arduino and Numeric KeypadsHello readers Another month, so time for another kit review. In this article we exame the LoL Shield by Jimmie Rodgers. So what’s all this about? Simple – the Lol Shield is a shield with nine rows...
Kit Review – the LoL ShieldWelcome back fellow arduidans! This article continues with the push-wheel switch introduced recently. In the previous article, we learned how to read the value of a single digit using the digital...
Tutorial: Arduino and multiple push-wheel switchesWelcome back fellow arduidans! In this article we discuss how to use the Microchip MCP23017 16-bit serial expander with I2C serial interface. This 28-pin IC offers sixteen inputs or outputs – and...
Tutorial: Maximising your Arduino’s I/O portsWelcome back fellow arduidans! In this article we go back to the past via the use of push-wheel/thumb-wheel switches with out Arduino systems. Here are some examples sourced from somewhere on eBay...
