Raspberry Pi’s power consumption is increasing with each version. Increased power usage cause core temperature to rise. We can monitor the Raspberry CPU temperature without an external temperature
Digital clocks are affordable and ubiquitous. In this post, we will build a digital clock using ESP32 and TM1637 on Arduino platform. There are several TM1637 based 4
TM1637 is versatile LED driver and keypad scanner chip. There are many 4 digit 7 segment display boards readily available in the market. In this post we will
You might have seen some kind of large token display systems in hospitals and other waiting areas. In this post we will develop a token display system using
I have described about TM1637 interface protocol here. In this post we will see how control TM1637 using arduino uno board. We will implement a counter that counts
TM1637 is an inexpensive LED driver come keypad scanner. There are many 4 digit 7 segment displays in market that uses TM1637 LED driver. It can driver upto
