Sameer Gupta tipped us with his latest project, a DIY Quadcopter: “Drone The Quadcopter” is an featured UAV. I design my project with F450 arm in X-mode design. The full operation takes place via a Flysky FSCT6 remote control unit which gives a better operating range of 800 Meter to 1.2KM. Drone The Quadcopter – […]
Everything You Need To Know About Bluetooth beacons in A White Paper
https://www.electronics-lab.com/everything-need-know-bluetooth-beacons-white-paper/
Bluetooth 4.0 introduced the Bluetooth low energy (BLE), which is a version of Bluetooth protocol designed for devices with power constraints like battery powered sensors. Bluetooth low energy beacons are BLE (Bluetooth Low Energy) enabled devices, they repeatedly broadcast radio signals to nearby smartphones, containing a small amount of data. Mobile apps can listen to […]
How to compare your circuit requirements to active-filter approximations
https://www.electronics-lab.com/compare-circuit-requirements-active-filter-approximations/
By Bonnie C. Baker (WEBENCH® Senior Applications Engineer): Numerous filter approximations, such as Butterworth, Bessel, and Chebyshev, are available in popular filter software applications; however, it can be time consuming to select the right option for your system. So how do you focus in on what type of filter you need in your circuit? This […]
