In this video, Circuit Basics walks us through the steps to change the screen rotation on an LCD touchscreen for the Raspberry Pi. Since there are separate drivers for the display and the touchscreen sensors, we need to change the orientation of both. It's pretty simple to do, but a...

Sometimes it may be necessary to use a display when making a hardware project, but one confusing thing is the size of the display and the required pins to control it. This tutorial will show you how to use a small I2C OLED display with Arduino using only two wires. The display...

A new competitor to Raspberry Pi Zero W is just out! A new single-board computer by Orange Pi that is now available at AliExpress is competing against Pi Zero W, the Orange Pi 2G-IoT. Using this powerful SoC you can build a computer, a wireless server, games, musics and sounds, a...

Massimo Gottardi@ edn.com writes: The Design Idea in Figure 1 is a color detector capable of generating an RGB triplet over a high dynamic range, a useful attribute for machine vision applications. The circuit implements auto-exposure control to achieve this. Thus, RGB values for a...

The LT8641 is a monolithic, constant frequency, current mode synchronous (external schottky diode is not necessary) step-down switching regulator. Its 3V to 65V input voltage range makes it ideal for 12V or 24V automotive and industrial applications. It delivers up to 3.5A of...

A teardown of a TDA7375 audio amplifier IC from Electronupdate: The TDA7375 audio power amplifier. Another example of a long-lived integrated circuit.  1st introduced in 1998… looks like it’s still being made. Teardown of a TDA7375 audio amplifier IC -...

Tom from Magic Smoke writes: This is my first time designing a PCB for MSP430. I really like the NRF24L01+ booster pack but I would like something smaller to use for remote temperature sensors. With that in mind I’ve designed a 24.5 x 50 mm PCB (2 on a 5×5 cm prototype) featuring...

AUTomotive Open System Architecture (AUTOSAR) is a worldwide automotive consortium trying to create and establish an open and standardized software architecture for automotive electronic control units (ECUs). However, as is always the case with industry consortiums and standards, they are...
