Story I have a nice “carranca” (or wall mask) from Chile that stands in my corridor. It’s a very beautiful decorative mask that I liked from the very first moment I saw it at the shop. Few weeks ago I wondered if I could bring it to life by adding a motion sensor and some …
Story I have been collecting data from Raleigh’s trails and parks for the last couple years. My primary platform has been a custom Arduino board I developed for low-cost (hey, these things may get damaged or stolen) and long battery life. I wanted a connected sensor to provide current data and, after looking at various …
These days theft has become a serious crime. People are now much more conscious towards there precious items are purses and jewellery but due to the busy routine of this life we are not able to take care of our things. That constant detraction of threat is a great problem. But don’t worry, I am …
This instructable will guide you to use a flame sensor with the Mediatek Linkit ONE. A flame sensor is a device that can detect the presence of fire nearby. A buzzer connected to linkit one beeps when fire is detected by the sensor. …
Do you face such situations when you leave your reading lights, table fans or soldering irons without switching them off and later realize that they were on for too many hours which subsequently jumps off your electricity bills? Well, if you have such a problem of forgetting things which probably most of you would have …

InLinea01 is a simple PID controlled line following robot. This is not speed oriented line follower, this is just a prototype I built to experiment with this type or machines, though it can be the first step to build a faster one. The goal of a line following robot is follow a line that is draw on the …

I have been experimenting using different ESP32 development boards, recently I ordered of the TTGO T-Beam variety which come with a Battery socket to add your own 18650 Lipo, this really takes some of the power regulation complexity out of building a small robot, as it has the battery and charger circuit in place already. …
Having already experimented with creating a robot using a cheap motor driver board, I decided to look at the one provided by Kitronik, I liked the look of it as it came with easy to use screw terminals to attach wires and had 4 inputs by default. …

One way to extend the functionality of the micro:bit is to use a board called moto:bit by SparkFun Electronics (approximately $15-20). It looks complicated and has many features, but it isn’t hard to run servo motors from it. Moto:bit allows you to run more powerful motors than the tiny micro-motor that you can run from the micro:bit …

Based on the Atmel ATtiny12L-4PI microcontroller -A real Time Clock/Calendar for less than US$1.50 in moderate quantity. This is the timekeeping test circuit. It includes a one-transistor circuit to switch in the 5V power supply when present and drop back to the 3v battery the rest of the time. That loop of blue wire-wrapping wire …
