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
All digital clocks experience clock drift. They need to periodically synchronisation with reference clocks. Networked devices such as PCs and smartphones use Network Time Protocol (NTP) for clock
ESP32 is an inexpensive IoT chip. ESP32 makes it easy to add internet capability to embedded systems. We have seen how to develop a token display using Arduino
Data centers and racks full of servers with multi-core processors comes to mind when we think of web servers. For small webpages, we don’t need all these big
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
ESP32-CAM is an inexpensive ESP32 based video processing board. It comes with ESP32-S AI-Thinker module and 2MP OV2640 camera. Seems the board is designed such that It can
ESP32 supports many development platforms such ESP-IDF, MicroPython and Arduino.We had already seen how to interface servo with esp32 using ESP-IDF and MicroPython. In this post we will see how to
