Here’s the Arduino version of a project to use the General Instruments (GI) SP0256-AL2 vintage speech synthesis chip to say “hello world”. I’d previously shown how to do this with a Basic Stamp 2. Here’s what it sounds like saying, “hello world” 20101215_164333.mp3 How it works, in short, is that the GI chip must be […]

Si4707 Hookup Guide
Introduction Weather-band radio is an awesome public service provided in the US, Canada, and Bermuda. With hundreds of transmitting stations dotting the country, weather radio acts as the “voice of NOAA” (National Oceanic and Atmospheric Administration). In addition to spouting out weather forecasts, weather radio also implements a messaging protocol for emergency weather alerts called […]
Arduino UNO Tutorial 6 – Rotary Encoder
We have written a tutorial for Rotary Encoders using a Microchip microcontroller but now would be a good time to make an Arduino UNO version. With a rotary encoder we have two square wave outputs (A and B) which are 90 degrees out of phase with each other. The number of pulses or steps generated […]
Arduino LEDs
Description In this tutorial you will set up and turn on a single LED. Note that this code can actually be executed with just the Arduino and no other components as in Figure 5. If you notice, next to pin 13 is a tiny LED on the board. If you execute the code below, you […]
Arduino Leonardo AVR Development Board
Arduino Leonardo AVR Development Board is a microcontroller board based on the Atmel ATmega32u4. It offers 20 digital IOs (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. The Arduino Leonardo differs […]
Android Phone Controlled Robot using Arduino
The Android phone that stays in your hand most of the time is useful in many other applications apart from Whatsapp, Facebook; appliances; monitor your health parameters. How it would be if it can control a Robot, which can assist in your daily work. With this project you can make a robot that can be […]
Servo powered peristaltic pump controlled by Arduino
This instructable shows you how to make a pump using a servo motor and an Arduino Uno to transfer small amounts of liquids. The pump is a peristaltic pump which consists mainly of a motor, flexible tubing and a circular pump casing. Two rollers attached to a turning rotor press the flexible tube to the […]
Use A Simple Cheap Webcam To Make DIY Microscope
This Project Is A Part Of The Afrimakers Event http://www.afrimakers.org/ Introduction We used a simple cheap webcam to make a microscope. In short, a small hack to the optics of a standard webcam with an adjustable focus-lens, allows to create video data, with a magnification of around 100 to 400x (depending on the model) at […]
Temperature Sensor v2.0
Overview This board allows you to use a thermistor to measure the temperature of something. It is designed to be used to measure things in the range of 100C – 300C, but with the proper calibration and resistors, it can be adapted to any temperature range you need (under 300C). If you need something that […]
