PWM with STM8S

PWM is a great way to control brightness of LEDs, speed of motors, etc. Most microcontrollers including STM8S has built in ability to generate PWM signals. In this article I share simple code to generate PWM signal in STM8S microcontroller. However, I don’t write anything about PWM theory other than basic calculation to get required… Continue reading PWM with STM8S

Bootloader-less Programming Arduino Pro Mini

Recently I was creating a configurable timer circuit based Arduino Pro Mini. The circuit has a momentary push button which user can press to turn ON the device. The device will turn OFF itself once the time is elapsed. On starting, Arduino has to turn on a relay to get permanent connection to power source,… Continue reading Bootloader-less Programming Arduino Pro Mini

Install Driver for TP-Link TL-WN823N in Raspberry Pi 2 Model B

Recently I brought TP-Link TL-WN823N wireless USB adapter to connect my Raspberry Pi over wireless network. Mine is Raspberry Pi 2 Model B, so not having built in wireless capability. I chose TP-Link TL-WN823N over Edimax EW-7811Un because of its 300 Mbps speed, both were available on amazon.in with similar price. It did not get… Continue reading Install Driver for TP-Link TL-WN823N in Raspberry Pi 2 Model B
