“With such a wide range of GSM modules available for the hobbyist, most of us ended buying one. I purchased a SIM800L module locally, and ended up playing with the different commands of the module. Using the Arduino Uno and …
“Last time I did the Hot wire foam cutter but I missed the temperature control. So that’s why I made a simple PWM control. The whole project was based on Arduino ATtiny85 Digispark. For this project I only needed …
“IoT (internet of things) environment monitor based on Esp8266 (NodeMCU), Arduino, Jquery, Django REST, Fritzing, the third industrial revolution, and the Hammond 1551k project box. Designed in Colorado by Object Syndicate. ioTank captures real time (every 300ms) sensor readings for …
“Hi there, today we are going to use Rfid(RC522 with 5110 screen. But this sensor is different than others. Because we will use EEPROM. We want to; 1 - When we show our ID card we see the ”Welcome Ensar …
“This tool is used to test capacitors. It is really easy to make, as only additional hardware needed (besides the capacitor that will be tested) is 2x220ohm resistors.”
“This work extends the IKEA-Hackant project from Robin Reiter , who reverse engineered the controller board of an IKEA Bekant motorized adjustable table. He added an Arduino board and four buttons to the controller, so that you can store two …
“Solar power meter measures the voltage, current and power of my 40W solar panel. On the PCB are two electrolytic capacitors, connectors, 3.3V stabilizer, ESP-01, voltage and current sensor INA219. OLED display is screwed to the box. The …
“One of the interesting usage possibilities for the RasPiO InsPiRing system is illuminated signage. What could be better than flashy, blinky, multi-coloured signage? Well, not much really? So I decided to make an arrow out of two straight 8s and …
“The pattern lock of Android device fascinates me. From the inspiration of Android pattern lock I made a physical pattern lock using IR sensors and Arduino microcontroller. You can use the lock where some sort of security is required such …
“Build an Arduino-powered version of the “Four Letter Word Generator” (FLW). This version generates “words” on the fly – it does not use a list. The “original” version from the 1970’s used B7971 nixie alphanumeric tubes. These tubes are getting …
