In this video educ8s.tv shows us how to use the Color OLED display with the SSD1331 driver with Arduino. It's very easy! A few weeks ago, I discovered this promising new display on Banggood.com and I thought that it might be useful in some of our projects so I bought it right away....

Omniblox, the Eagle .brd 3D viewer we previously covered here has released a new version that uses fonts and corrects rotation issues in silk screens. Code and instructions available on github. Omniblox – Eagle BRD 3D viewer update -...

byteparadigm.com has a nice introductory article on I2C and SPI protocols: Today, at the low end of the communication protocols, we find I²C (for ‘Inter-Integrated Circuit’, protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well-suited for...

Intersil announces the adoption of its latest family of buck-boost switching regulators in one of Huawei's newest smartphone. The ISL91110 buck-boost switching regulator powers the Huawei P9 smartphone's key system peripherals providing excellent efficiency and performance....

Scott @ swharden.com show us how to interface an analog signal to a microcontroller that doesn't have an ADC. I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method...

Susan Nordyk @ edn.com discuss about LTC2986 which is able to digitize and linearize a combination of temperature sensors in Celsius or Fahrenheit degrees. A 10-channel temperature-measurement IC, the LTC2986 from Linear Technology directly digitizes any combination of thermocouples,...

Lukas Fässler shares his Maximum Point Tracker Solar Charger Design based on PIC18F26J50: At the core of the design is a PIC18F26J50 in a 28 pin SOIC package. It’s capable of running at down to 2.15 volts and consumes extremely little power when running at lower clock speeds. And...

An open source CO2 monitoring project from Roving Dynamics: The project described below uses a MH-Z16 or MH-Z19 CO2 sensor and a DHT-22 (or DHT-11 if less accuracy is required) to measure the Temperature and Humidity. It has a 4 line by 20 character LCD Display to show the current...
