Arduino Altimeter Project Using BMP085

This Arduino Altimeter project features the BMP085 atmospheric pressure sensor by Bosch. Because atmospheric pressure is directly related to altitude above sea level, we can use this sensor to determine current height with respect to the height of the oceans. The height is given in meters and is displayed on …

NodeMCU WiFi Jammer

There is, in fact, a way to create a NodeMCU WiFi jammer although technically, this is a deauther and not really a jammer. A jammer sends out noise on the WiFi frequency spectrum (2.4 GHz) while the program in this tutorial sends packets that disrupts the normal functions of your …
