LIS3LV02DL is a MEMS three-axis digital linear accelerometer that provides both I2C and SPI interfaces for communicating with microprocessors. My […]
I was inspired by Paul’s 7 segment display and decided to build one myself. He used 4 common cathode 7 […]
I have been using the FTDI bitbang method piloted by Kimio Kosaka and improved by others (1,2,3) to flash Arduino […]
H-bridge is frequently used to control DC motors and stepper motors. When controlling a bipolar stepper motor, two full H-bridges […]
After going through some of the tutorials on Arduino’s site, I really started to appreciate what a powerful platform Arduino […]
When I first started interfacing electronics with computers back in the early 90’s my hardware choice was an ISA AD/DA […]
Using PC’s parallel port is a convenient way to control a stepper motor. For unipolar stepper motors, up to two […]
Using DTR (data terminal ready) and RTS (request to send) pins of a PC serial port (RS-232) without actually using […]
One of my older CRT TVs does not have a built-in degauss button and after sitting in the corner of […]
A touch sensitive on/off switch can be made with a single MOSFET. The following schematics illustrate such a switch using […]
