The damages that can be done by fire are devastating. To prevent causalities or damages, it is necessary to detect the fire, so that warnings can be provided and even automatic fire suppression ...

A cheap USB-programmable analog output is great for setting intensities, power levels, or general analog signalling in many experimental contexts. There are lots of solutions when you want one or two ...

The LM35 is a precision integrated-circuit temperature sensor (PTAT; proportional to absolute temperature) manufactured by Texas Instruments (https://www.ti.com ...

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

There is one thing that unites almost every computer and logic circuit commonly used in the hardware hacking and experimentation arena. No matter what its age, speed, or internal configuration, ...
