Various versions of the Arduino will reset the board by toggling the serial DTR line, a feature called auto-reset.  Since it relies on the DTR line, it won’t work with TTL serial adapters that don’t break out the DTR line.  After writing my half-duplex serial UART, I thought of using the TTL serial break signal […]

Microinverters provide an effective solution to solar-energy harvesting by providing power conversion at the individual panel level. The emergence of highly integrated MCUs offers an attractive approach to microinverter design, providing an option that reduces the cost of complexity which limited widespread adoption of microinverters in the past. Today, designers can build highly efficient microinverter […]

This instructable will tell you how to make and connect a soft potentiometer to a microcontroller, in particular we will connect it to a Lilypad Arduino. In our case soft potentiometer means a potentiometer made of a textile conductive ribbon. What you need: 1. soft conductive textile ribbon. The important thing here is that the […]

There are many ways to make your own homemade PCB’s, They all work, but some better than other, some faster than other, ones are cheap and others expensive…. After several attempts, i found the way of making PCB’s, which is the cheapest, easiest and fastest for me. I hope this instructable will help you to decide […]

In this Arduino UNO tutorial, we are going to use a Light Dependent Resistor (LDR) to create a simple childrens bedroom nightlight which turns on automatically when it gets dark and turns off when it gets light. An LDR’s resistance changes depending upon the amount of light hitting the sensor.  For the LDR we are […]

Sometimes I just have those days where I really want to make something neat with the Arduino I have lying around, but I know I don’t have the patience for a more involved project that’ll take more than a day or so. This is for one of those days. The premise is as follows: A […]

The “MYdata TPsys CAD converter” is a small universal program which read the pick and place export data of the most pcb design softwares out there, and converts them to a machine readable MYdata TPsys “.pcb” file, so that the smt machine is programmed quickly and you can save a lot of time and money. […]

I’ve been on mission lately to design a handheld bluetooth game controller. I’ve made a prototype in the past but, it never was really usable as a gaming device. Although the concept worked well the form factor was not quite there. Well after a few months of tinkering and several designs I finally have one! The design […]

I bought a small aquarium (54l) as an impulse buy and I needed some lights for it, so naturally I wanted to use LEDs. I also needed a timer for the lights. I also wanted the lights to fade in and out when they were going on or off as a cool effect. I ordered […]

Your own firefly light show anytime Watching fireflies is one my most memorable childhood events.  Every summer, I would look forward to watching fireflies dance with their seemingly random blinks.  I marveled at how a living creature could produce light all on its own.  Even today as I share this experience with my children, I […]
