Arduino Pressure Sensor Wiring Diagram - Objective of the tutorial. Well, the goal and the output of this tutorial is to build a low cost circuit able to: Power up a full bridge strain gage load cell (the 4 wires-one). In the mid 1970s large numbers of small FM transmitters, operating in the FM radio broadcast band (88-108 MHz) appeared on the market. It started with a self-build kit from the Danish manufacturer Jostykit that allowed everyone to build a small FM transmitter for a few Euros..
