Arduino sampling code and circuit schematic
The code implementation discussed in the previous post has been initiated. To improve organization, the code has been modularized into functions, simplifying the overall structure. It is available along with the other code. Challenges were encountered in calculating averages while...
twitterpop
After acquiring an Arduino and several 8x8 LED matrices, a project was initiated to effectively utilize these components. Concurrently, there was an increasing interest in Twitter and its API, leading to the development of a Twitter popularity meter. This system...
message in a bottle
Message in a Bottle is an Arduino microcontroller and sensor project that enables an individual to record their voice inside a glass bottle and send it to someone else for playback. By uncorking the bottle and speaking into it, the...
get on the blinkm bus with a blinkm cylon
BlinkMs are entertaining devices that function as small network components, each assigned a unique address on an I2C network. The potential of BlinkMs is particularly evident in their ability to simplify the control of multiple RGB LEDs. For a demonstration...
Arduino AVR High-Voltage Serial Programmer
This Arduino sketch is designed to recover ATtiny microcontrollers that have become non-functional due to incorrect fuse settings. It achieves this by placing the affected ATtiny into high-voltage serial programming mode and rewriting the fuses to safe values. The Arduino...
arduino code for buffalo ii dac lcd connection
For an effective tutorial on connecting a standard LCD to an Arduino and utilizing the standard LCD library, refer to the LadyAda Tutorial on LCDs. The diagram illustrates the fundamental connections with a standard LCD that is compatible with the...
Arduino Make your own hardware
The Raspberry Pi single-board computer (SBC) has garnered significant attention for being a complete system priced under $50. However, it is not the most affordable computing device available. For only $13.50, a mini computer that connects to a PC's USB...
Control the speed of a DC motor with a potentiometer with an Arduino board
A quick circuit showing how to control the speed of a DC motor with a potentiometer with your Arduino board. Also shows how to use a TIP120 transistor to allow the Arduino control a larger power supply.
This circuit utilizes an...
5-motor hexapod circuit
This circuit has a long history, originating from an idea by Rich Piotter and later refined by Wilf Rigter and Bruce Robinson. The final result does not include the necessary motor drivers, which are typically H-bridge based, but presents a...
