| The infrared (IR) decoder described here was designed to enable an E-Blocks development system to process commands from RC5 (compatible) rem...
| The circuit described here and its accompanying BASCOM software arose from the need to control the temperature in a laminator. The laminator...
| Pretty graphical simulators are all very well when developing circuits using microcontrollers, but sometimes there is no substitute for a pr...
| For devices where there's no need to read an LCD continuously, the backlight doesn't need to stay lit up all the time — several seco...
| Many simple function generators do not offer the facility to measure either the frequency or the amplitude of the output. The module describ...
| Not having enough ports on a microcontroller to drive all the functions of a circuit is a commonly-encountered problem. The clever port expa...
| With all the processing power under the hood of the Atmel ATtiny13 and ATtiny2313 micros, it’s not too difficult to get them interfaced to t...
| The cathode ray tube (CRT) has made way for the LCD and digital has replaced analogue technology. This trend is also evident in the design o...
| The backlights used in some LCD panels are not exactly economical: typical current draws of 20 mA to 100 mA are common. Normally the current...
