RADIO CONTROL CIRCUITS PDF

The 4017 traffic light circuit connects four legs to the green LED and two legs to the amber LED. This configuration raises the question of whether it could function with only one leg per LED. Each output is activated...

The transistors create a differential pair with an active current-source tail. This configuration, referred to as a variable-transconductance multiplier, produces an output that is proportional to the product of the two input signals. The multiplication effect arises from the...

Schaer is a generic programmer circuit capable of uploading and downloading firmware to and from several electronic devices, such as microcontrollers. The Schaer programmer circuit is designed to facilitate the transfer of firmware between a host computer and various electronic...

The transmitter is shown and although straightforward, there are a couple of tricks that I had to incorporate to minimise battery drain during standby. Although the PIC quiescent current is only 200uA, that will still flatten a pair of...

Here is a simple radio that is easy to build and inexpensive. In fact, you probably have all the parts you need in your junk box. You'll be surprised at the great reception with this little set. More: The...

A Chemetron wire feeder is being utilized, and there is a desire to use the speed control from the control box to regulate the motor it originally contained. The Chemetron wire feeder is designed for efficient wire feeding in welding...
