6 Digit LED Clock

I recently found six 2.3″ red 7 segment displays in my collection which I purchased from Rapid Electronics when they were clearing out non-RoHS stock. Since I have no clock at my work bench I decided to construct one from some prototyping pad board, a Microchip PIC18F26K20 microcontroller and a Dallas DS32KHZ temperature compensated 32.768kHz crystal. The displays I used are SA23-12SRWA, which don’t appear ...

Line Follower Robot using Arduino

Line follower Robot is a machine which follows a line, either a black line or white line. Basically there are two types of line follower robots: one is black line follower which follows black line and second is white line follower which follows white line. Line follower actually senses the line and run over it. Concepts of Line Follower Concept of working of line follower is related to light. We use here th ...

Live Temperature and Humidity Monitoring over Internet using Arduino and ThingSpeak

Humidity and Temperature are very common parameters for measuring at many places like farm, green house, medical, industries home and offices. We have already covered Humidity and Temperature Measurement using Arduino and displayed the data on LCD. In this IoT project we are going to Monitor Humidity and Temperature over the internet using ThingSpeak where we will show the current Humidity & Temperature ...

An adapter with standby power consumption below 0.1W already on stock

DoE 2016 is a known term naming stringent regulations established by DoE (department of energy USA) valid from year 2016. Among other things it brings a requirement for a standby power consumption of small adapters to be below 0.1W. In Europe we have here a limit of 0.5W for majority of small adapters, but even here can be expected toughening in the nearest years. That´s why German company Friwo as a long-t ...

Arduino Based Digital Thermometer

Thermometers are useful apparatus being used since long time for temperature measurement. In this project we have made an Arduino based digital thermometer to display the current ambient temperature and temperature changes on a LCD unit in real time . It can be deployed in houses, offices, industries etc. to measure the temperature. This project is based on Arduino which communicates here with LM35 temperat ...

Frequency Counter using Arduino

Almost every electronic hobbyist must have faced a scenario where he or she must measure the frequency of signal generated by a clock or a counter or a timer.  We can use oscilloscope to do the job, but not all of us can afford an oscilloscope. We can buy equipment for measuring the frequency but all these devices are costly and are not for everyone. With that in mind we are going to design a simple yet eff ...

Short circuit protection for (almost) any power supply

Hello, everyone! This instructable is about a universal short circuit protection that I've designed to use in bench power supplies. I've designed it to fit in most power supplies circuits. In order to this circuit fit in your bench power supply, you will need to do some calculations, but don't worry, I'll explain everything on the next steps. The circuit is really easy to understand. A resistor of low value ...

Interfacing Arduino with Raspberry Pi using Serial Communication

Raspberry Pi and Arduino are the two most popular open source boards in Electronics Community. They are not only popular among Electronics Engineers but also among school students and hobbyists, because of their Easiness and Simplicity. Even some people just started liking Electronics because of Raspberry Pi and Arduino. These boards have great powers, and one can build very complicated and Hi-fi project in ...

The CANable: a small USB to CAN adapter

The CANable is a hardware clone of Eric Evenchick’s CANtact project, an open-hardware USB to CAN adapter compatible with socketcan. I took his design and reworked the hardware to be a bit more suitable for my personal needs, with a screw terminal instead of a DB9 connector and a much smaller PCB. The design is open-source hardware and the schematic is nearly identical to CANtact except CANable uses the STM3 ...
