AC (Alternating Current) is used for the transmission of mains voltage, one of its main advantages for use as a method of transmission over DC (Direct Current) is that a change of voltage between High Voltage, Low Voltage, and SELV (Safety Extra-low Voltage) can be performed using a transformer. A […]
Ohm’s law (sometimes written as Ohm law or Ohms law) is one of the fundamental first principles of electronics. The law was named after the German physicist Georg Ohm and states that the electric current through a conductor between two points is directly proportional to the voltage across the two […]
The MCP23017 is a popular I2C 16bit IO module, it can be used to allow you to have more GPIOs available, There is also the MCP23018 available, which does fundamentally the same as the MCP23017, but with a few differences: On an I2C bus, each device has a unique address, […]
First, we are going to cover some basics in this case Resistors, but, to do this we are going to tell some lies, if you know what the lies are, then chances are that you don’t need to read this post… but please do anyway. Resistors’ values are measured in […]
