Build a simple 9600 BAUD 8n1 LCD terminal for debugging and testing the projects having RS232C output. Introduction This LCD terminal provide two modes of operation by selecting jumper J1. When J1 is open the terminal operate as a normal ascii display terminal, when J1 is closed the terminal displays the input serial data in […]

A new method of processing signals via fiber optic cables could vastly increase the distance at which error-free data is transmitted via submarine cables without additional signal amplification. As the technique is capable of correcting corrupted or distorted data being transmitted, it may also assist in increasing the capacity of all optical fiber communications. With […]

If you ever wanted to do a project involving microcontrollers, the first thing you need is a microcontroller, and programmer. Many commercial PIC programmers exist. These programmers cost anywhere from 25 to 250 dollars depending on how many different PICs are supported and how greedy the manufacturer is. In my other article, I gave a […]

The electronics trend in automotive is continuously rising due to the demand in the market. The technological developments are now into embedded system in which the manufacturers are developing products that suits to the needs of the people. In this design, it features a automotive lighting control using an MCU with S12 CPU core, 25 […]

Methods: Use a TTL HI output for the RS232 GND: Steve Walz of armory.com says “Use a TTL HI output for the RS232 *GROUND*!! Then you get +/-5VDC levels to fake out the RS232. When TTL-GND goes HI, then a TTL-XMT LO looks like -5VDC and a “mark”. Even sign problems go away in hardware! […]

AVR ATTiny85 microcontroller running at 8MHz internal clock and 3.3V. ATTiny85 Datasheet. HM-10 Bluetooth 4.0 Low Energy module. HM-10 Datasheet. Powered by single cell 3.7V […]

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, and Digilent, Inc. announced expanded capabilities for the 32-bit PIC32 microcontroller-based chipKIT™ Development Platform for the Arduino™ community. The chipKIT development platform is a 32-bit Arduino solution that enables hobbyists and academics to easily and inexpensively integrate electronics into their projects, even if […]

If you´re searching for an enclosure with a high variability and for a reasonable price, then we can recommend you the EH basic series enclosures. Searching for a compromise between the quality (materials, design,…) and production costs is a theme at development of every device and naturally – also at development of components. Also from […]

AN589 is microchip’s application note for a parallel port pic programmer circuit which I chose as I wanted something reliable to get up and running quickly. It is really quite a simple circuit and its main objective is to provide ICSP connections to your pic microcontroller. Here is the pcb version (click to enlarge): Note: […]

After CNCPaul/LathePaul created such an awesome-looking heating chamber, the postie once again knocked on the door at Nerd Towers to deliver yet another eBay purchase – this time, it was a K-type thermistor and breakout module (basically just a MAX6675 on a board with pin headers) We  had looked online at temperature controllers but they […]
