Electronic Control Device
The first electronic medical device to be made is the relay. It was invented in 1835 by John Henry, who was an American scientist.
You build an electronic device to control a transistor switch that causes a mechanical device to push the switch. Now days we bypass the mechanical switch and the circuit can do the switching.
Philo T. Farnsworth he did in fact invent this device.
first----->he invented the first electronic video camera tube. second--->from that he invented the first electronic television third----->he invented the fusor device. it is one of nuclear fusion device. fourth---->he contributed in the making of electron microscope
A remote control is used to control an electronic device form a distance without wires. It uses infrared or radio frequencies to transmit the data to the device.
Probably the machine that can go at the speed of light that was invented in 2012.

Any device that uses the control of electrons to operate. So, anything battery operated or anything you plug in that controls the flow of electrons would constitute an electronic device. So, for example, a telephone is an electronic device, and a vacuum cleaner sort of blurs the line but can be considered an electronic device these days because there have to be semiconductors at least in the power supply.

The theremin device was one of the first electronic music instruments. It was the first to be mass produced. It was invented by Lev Sergeyevich Termen.
