In this project, we’ll design a wireless joystick dc motor controller using ATtiny85 and Arduino. It will offer a long range, operating up to 1 km. (You can learn how to control the joystick’s motor speed and direction using Arduino in this article.) Wireless joystick controls for dc motors are used in many industrial, domestic,…
How to make an IoT-based analog clock using ESP32
In this project, we’ll design an analog display clock using ESP32. The clock is an Internet-of-Things (IoT) device that retrieves the local time from a Network Time Protocol (NPT) server and displays the time (as well as the date) like an analog clock. The display used to build this IoT clock is SSD1306. However,…
How to use Arduino’s analog comparator
Arduino boards have a built-in analog comparator used for different applications. This is noteworthy because digital input/output and pulse width modulation (PWM) are typically used while analog comparators are not. A built-in analog comparator is useful in microcontrollers, providing voltage comparisons, digital-to-analog conversions, threshold detection, and PWM. Depending on the Arduino board (there are several…
STMicroelectronics launches 2.5V digital-to-analog converter for satellite applications
STMicroelectronics‘ RHRDAC121 radiation-hardened, digital-to-analog converter (DAC) operates down to 2.5V for use in modern, low-power system designs that older 3.3V parts cannot support. Consuming just 0.6mW at its maximum speed and supply voltage, the 12-bit 1Msps successive approximation register (SAR) DAC helps reduce size, weight, and power (SWaP) in next-generation satellites. Typically used in circuits…
How to program an OLED display with Arduino
Sensors are used to convert a physical quantity, such as light intensity or temperature, into an electrical one. There are several types of sensors that can easily be used with an Arduino board, which is an advantage. For example, any analog or digital sensor easily interfaces with Arduino as the board offers both analog and…

The VN9D30Q100F and VN9D5D20FN from STMicroelectronics introduce a new generation of automotive intelligent switches — the first in the market with digital current sensing among the fully digital on-chip diagnostic features. Designed for high-side connection in applications powered from a 12V battery, the drivers simplify the hardware and software design of electronic control units (ECUs)…
Insight – How Analog Speedometer Works
You may know how to drive or you are just like me who always tag along as side kick, but there is one part of automobile that is voluntary known to each one of us “Speedometer”. You may not be driving but one step on accelerator by the driver and you are squirming on your seat just as the needle on the meter. Ha!We have never really thought how does a needle move on the meter? What makes the number change on odometer? We look at speedometer but never really notice it. But not anymore join me in this insight to learn all about speedometer. Let’s understand in depth all about it.
An Introduction to Analog Electronics
The world of electronics is all about electrical circuits, electronic components, and interconnected technologies. All these elements can be primarily categorized as digital, analog, or a combination of both. However, here we will be focusing on the basics of the analog category in detail. Analog electronics is a branch of electronics that deals with a continuously variable signal. It’s widely used in radio and audio equipment along with other applications where signals are derived from analog sensors before being converted into digital signals for subsequent storage and processing. Although digital circuits are considered as a dominant part of today’s technological world, some of the most fundamental components in a digital system are actually analog in nature.
