In this post we are reviewing the ESP-01 Wi-Fi Relay Module. It is one of the cheapest smart switches you can purchase currently for making smart home, internet of things, and other wireless do it ...
CH_PD: chip power down pin, used to turn off the ESP8266EX chip, when high the chip is enabled and when low the chip is off, also named as CH_PU (chip power up) and CHIP_EN (chip enable) GPIO2: ...
At the heart of the ESP-01 module is the ESP8266 chip with at least two boot modes — the normal mode and the programming/flash mode. The latter refers to uploading any software (or firmware) to the ...
The ESP-01 module based on the ESP8266 is all the rage with IoT folks at the moment – and why not. For about 5 bucks, it can’t be beat on price for the features it offers. The one thing that such ...
Looking for practical Arduino projects? This guide shows how to control a relay from your smartphone using an Arduino Uno — either via Bluetooth or Wi-Fi with an ESP8266 ESP-01 module. With ...
Hi! Thanks for this part. On my ESP-01 (and from what I have seen on the Internet, other people) fritzing pin4 is in fact connected to /RESET not to GPIO-16. This pin works as a reset on my module. In ...
In this article, we will explore a straightforward method to create an IR remote-controlled FM radio with RDS (radio data system) using the ESP-01 module. We will utilise the Arduino IDE for software ...
