This project is to make a simple RESTful Web service library for IoT Devices. The library is written with C language code and on WIZwiki-W7500ECO platform board from WIZnet. With it, users can implement a RESTful Web service on IoT devices easily. Monitoring IoT devices can be done by RESTful API based on JSON, as […]

Have you ever been anxious to receive your new break-out boards, only to find out that the pin layout is not breadboard friendly? If only those pins were aligned differently. Well, let me show you how I have made an easy breadboard adapter that will fit the nRF24 or ESP8266 boards. No modifications or soldering

Tiny Basic Controller (TBC) is a simple device that can operate as a PLC (program logic controller) for home automation, control, etc. For example, this one can dial-up by modem to the remote computer and control the system, can control some processes, temperature regulation, battery charging, can be used for education and hobby purposes. TBC is

This fun project lets you take control away from the person holding the remote control by intercepting the invisible signals as they travel through the air so you can play them back to the TV or video machine. You can also “train” your Remote Hijacker by recording certain button presses directly from the remote so

The MCP4725 DAC is a pretty common and cheap single channel 12 bit buffered voltage DAC, it also has an onboard EEPROM. To drive this chip we can use I2C interface. The ATmega8 used for my implementation has an embedded I2C interface, so we just can use that interface. The selected I2C library is the one proposed by Peter Fleury,

Contact bounce (ref. https://en.wikipedia.org/wiki/Switch#Contact_bounce) is a common problem with mechanical switches and relays. Switch and relay contacts are usually made of springy metals. When the contacts strike together, their momentum and elasticity act together to cause them to bounce apart one or more times before making steady contact. You can find below a sample of a bouncy
