This is an Arduino tutorial on how to detect lightning from far away. In this tutorial, we will build a lightning detector using an Arduino Uno, a few resistors and some jumper wires. Most lightning detectors often cost too much for the normal hobbyist, however this does not mean one...

"bogdan" published a new project, a device able to automatically reset your router, camera or server. AutoResetRRR is a kind electronic frustration reducing device: it cuts the power periodically to devices that can go nuts (routers, net cams, servers), but it does give a heads up....

Marko Pavlin has published a USB to RS485 converter. He writes: Testing of sensors with RS485 using PC without proper interface is not possible. Since RS232 interfaces are very rare, the interface should be hooked to USB. The interface between USB and RS485 can be soldered with one...

Optically isolated parallel port  break out board designed for Hobby CNC, Routers and Motion controller, This Board is an easy solution to drive stepper Motor driver through PC parallel port, The Board is compatible with various CNC software specially made for LPT port data output....

In this video educ8s.tv is  going to show us how to use the SD card slot of the popular 1.8" Color TFT display which uses the ST7735 driver. Then we will save some bitmap images in the SD card and we will display them on the display. In other words, we will build a simple Photo Frame...

LTC3896 is a high voltage inverting switching regulator controller that drives an all N-channel synchronous power MOSFET stage. Most low to medium power inverting DC/DC converters use a coupled inductor or transformer: this device uses only a single inductor. The chip converts a 4V...

Jason Jones has tipped us with his latest project. He is working on a semiconductor curve tracer and details his progress on his website. I have thought about this a lot recently and - in order to get the cost down - the unit must have a cheap or available power supply and must coopt...

This is a tutorial on how to use a 433MHz long range transmitter/receiver with Arduino. I just explain how i have use the 433MHz RF Long Distance Transmitter / Receiver Pair and a arduino to install it on my rc truck for a firework ignition, lamp , pan tilt camera system How to Use...
