A digital soil moisture meter is used for indicating the water content of a given soil sample. As crop production requires water at different stages and in different amounts, it is important to measure soil moisture from time to time to know its status. The digital soil moisture meter circuit presented here, for monitoring the

The miniscule event counter based on a microcontroller is built using the affordable Digispark Attiny development board. A benefit of this design is that it can be connected to its trigger input regardless of whether it is an active or passive switch. Every time the switch is turned on, the microcontroller will count the event

Precise measurement of line signal frequency is very important in many applications, especially in the management of power grid systems. Tasks like calibration of governors of engines that run generators in power plants need a resolution up to 0.01Hz. Frequency is also an important parameter in load sharing among several power plants in the grid.
