With the local oscillator working entirely, the next step is checking to see if the signal goes through the bandpass filters properly. To do this, I needed to program the arduino to select the ...

Arduino script to control a 5V Noctua A6x25 PWM fan (or any other 5V PWM fan) with the onboard Arduino Leonardo on an Udo Bolt. I got one of the first Udoo Bolts in 2019. As its fan was horribly noisy ...

Powering an Arduino has a little magic to it. It wasn’t obvious to me when I first started working with them, but Arduinos have on-board regulation. Taking advantage of this allows for longer power ...

If your introduction to digital electronics came more years ago than you’d care to mention, the chances are you did so with 5V TTL logic. Above 2V but usually pretty close to 5V is a logic 1, below ...

The sensor has 3 wires RED, YELLOW, and BLACK as shown in the figure below. The red wire is used for supply voltage which ranges from 5V to 18V and the black wire is ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

In this article, I am going to explain how we can design and assemble a battery charge meter through the assembly of a circuit with Arduino. It is very common to have various electrical devices around ...

The ESP8266 is the reigning WiFi wonderchip, quickly securing its reputation as the go-to platform for an entire ecosystem of wireless devices. There’s nothing that beats the ESP8266 on a capability ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...
