The circuit in Figure 1 produces a single debounced pulse each time you press S1. Moreover, the circuit uses only logic power from the remote pull-up resistor, R2. You can use the circuit to detect when a key is pressed in a non-energized device, such as a device in a system that’s just coming up from […]
Stereo volume and balance control with Rotary Encoder using MAX5440
https://www.electronics-lab.com/stereo-volume-balance-control-rotary-encoder-using-max5440/
The project described here is a compact stereo volume and balance control with rotary encoder. It provides 32 log potentiometer steps with buffered wiper output. The project can easily replace mechanical potentiometer. 5 LEDs indicate the volume level or balance settings , depending on the status of the mode indicator D1 LED. The MAX5440 includes […]
Arduino Button Debounce Tutorial
https://www.electronics-lab.com/arduino-button-debounce-tutorial/
One of the major problems encountered when using push buttons and switches in digital electronics project is the problem of bouncing. When we press a button once it may register twice and when we press it four times, in a row, it may register just twice. This occurrence is due to a property of switches […]
