LED Matrix Display using Arduino

Engineeering Projects

Today, I am going to teach you how to make an LED matrix display using Arduino. Here we had designed a 7×5 LED matrix display but can be extended as per desire. If you are using Arduino uno board the number of rows can be extended up to 14 and the number of columns can be extended up to 6. This is because there are only 14 digital pins (D0 to D13) and 6 analog pins (A0 to A5). Thus, you can make a 14×6 Led matrix display in the…

Today we come with a unique idea i.e. Photodiode using LED. This project utilized an LED to detect and respond to the presence and absence of light. Before starting the description and working of circuit DIY Light Detector Circuit using LED, we would like to describe a few electronics components. LED: Light-emitting diode is a photoelectric device that converts electrical energy into light energy. It is a heavily doped P-N junction diode that under forwarding bias emits spontaneous radiation. Photodiode: Photodiode is an optoelectronic device in which current carriers are…

sound meter circuit

The project sound level meter circuit shown here comprises a display circuit for 10-segment resolution i.e. used to indicate sound level up to 10 levels. Recording of sound in the studio involves critical adjustment of recording levels and level of bias current. If the level of sound is very much it may cause some distortion while a low level of sound reduces the SNR (Signal to Noise Ratio) as a result the sound may be too noisy. Care should be taken while recording sound to regulate the signal so that…
