The RFduino compass is a fully functional stand-alone compass which also transmits the current heading via Bluetooth low energy technology to phones, tablets, personal computers or any other equipped device. The RFduino compass is known as a Bluetooth Smart device. While other combinations of materials may be used, the ones used for this project and […]
This is a small dev board I designed to make experimenting with and deploying the ESP8266 ESP-03 modules a bit easier. As well as breaking out all the pins to 2.54mm headers it has a position to fit either a DS18B20 temperature sensor or a DHT22 temperature/humidity sensor plus the required pull up resistor. It can

C020 This project is a RS232 to RS485 interface module Description This project provides a simple and easy solution to connect your computer to a RS485 Network in either Receiver or Transmitter mode. This circuit has been designed around popular MAX232 and MAX485 interface IC. An Onboard 9 pin female D connects this PCB to

This project starts a few weeks ago. My six years old daughter usually sleeps with a light on in her bedroom. Talking with her, we decide to hack her LAMPAN Ikea lamp to make some improvements, including a manual RGB controller to set the light colour, a timeout to turn off the light after 30

Nextion is a Seamless Human Machine Interface (HMI) solution that provides a control and visualisation interface between a human and a process, machine, application or appliance. Nextion is mainly applied to IoT or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube. This solution includes hardware part
This chimera is a microcontroller emulation of a UK101, an 8-bit microcomputer from the early 1980s. Needless to say I had one; it is a shocking thirty-three years since, as a spotty teenager, I soldered one together over the course of a few days. I recall the kit cost the equally shocking sum of £99.95 (a lot of pocket-money), and

Hi all! With a bit of delay, here’s my last work, a PICnano breadboard based on the PIC18F2550 microcontroller. I have in mind a new project and I want to use an small board, like the Arduino Nano board. This new project is battery powered (3,7V Li-Ion battery). After checking the schematics of the Arduino

I ordered this awesome N|Watch kit the other day, which requires some serious SMD hand-soldering skills. There’s always the easy alternative to use a reflow oven, but guess what, there is no stencil included (and no, I don’t have a paste dispenser). In a desperate need of a third hand (!) in order do a
In this Instructable, we will be building a compass using the TinyShield Compass as well as the Circle Edge Led shield. Before starting, the proper drivers must be installed to detect the COM ports. These drivers must be installed before downloading any codes from the codebender plugin. The drivers needed can be found here. Lucky

In embedded systems, oftentimes it is needed to generate analog outputs from a microcontroller. Examples of such include, generating audio tones, voice, music, smooth continuous waveforms, function generators, voltage reference generators, etc. Traditionally in such cases the most common techniques applied are based on Pulse Width Modulation (PWM), resistor networks and external Digital-to-Analog Converter (DAC)
