LED lighting is becoming more important in every car segment: It increases road safety and enables new design trends, such as flexible styling. To address the resulting requirements, Infineon Technologies is expanding its LITIX Power family with the dual-channel, stand-alone DC-DC controller TLD6098-2ES. The controller is the first product that can drive a full LED…
Contactless temperature measurement guns have become very popular during Covid times. Almost all the places had the device to ensure safety protocols. However, one of the drawbacks of the current contactless temperature measurement guns available today is that they measure body temperature – not the distance of the body (object) from the sensor. The body’s…
The majority of sensors have an analog output. Few sensors come with a built-in controller and can stream the output measurements over a digital protocol. That is why analog to digital conversion is one of the basic features that every microcontroller/port has. The other basic features include digital input/output, analog output, PWM generation, and serial…

Microcontroller boards require communicating data with a lot of other devices that include sensors, actuators, other microcontrollers, and microcomputers. This data transfer or exchange is carried over serial interfaces using standard protocols like UART, I2C, SPI, 1-wire, etc. UART is one of the common serial data communication protocols available on almost every microcontroller. UART is…
8255 is general purpose programmable peripheral interface. It is used with many microprocessors and microcontrollers for various purposes. The device has three 8-bit ports port A, port B and port C. These ports can be used as input or output. These ports are further divided in to two groups A and B. Each group further…
The proposed simple electronic spy Bug circuit is basically a high gain amplifier using the IC 741 as the heart of the circuit and also a couple of high gain output transistors. The IC 741 if configured as a non-inverting amplifier which performs the function of a pre-amplifier stage. The gain of this IC 741 preamplifier stage may be varied as desired, using the pot across its input and output pin outs. The gain setting is used to set the sensitivity of the amplifier and is set to maximum so that even low volume speech conversation may be picked through it. The mic at the input transforms sound vibrations into minute electrical pulses, which is further amplified by the IC 741 to suitable levels before applying it to the output amplifier stage consisting of a standard DARLINGTON stage. This Darlington stage is made using a couple of high gain transistors bc107A’s.
