WebApr 30, 2024 · ESP8266: Interfacing MAX485 TTL-to-RS485 on serial port. I am using the ESP8266 NODEMCU. I am aware that the CH341 on the NodeMCU is bridged to the serial pins GPIO3 (Rx) and GPIO1 (Tx). Hence, any data send on Rx and Tx is also visible on the serial monitor. I need to interface MAX485 TTL-to-RS485 to the ESP8266 on different …

WebLet us demonstrate an example of RS485 serial data transfer between an ESP8266 NodeMCU and a n ESP32 board using the MAX485 TTL to RS-485 module. Our aim will be to send ADC values from the master ESP8266 connected with a potentiometer through the RS485 module to the slave ESP32. The slave ESP32 will be connected with an LED and an … WebTutorial Summary.

WebMay 6, 2024 · Several TTL outputs in paralel. I was using Sparkfun PIR motion sensors with open collector output. I have used multiple motion sensors connected to a single input pin (pulled up to 5V) on Arduino and if any of the motion sensors triggered, the input pin was pulled low. Recently I bough couple of these eBay PIR motion sensors with TTL output. WebHi guys, in this tutorial I will show you some NPN transistor based logic gates. What you need. -A breadboard. -A bunch of 5k and 10k resistors, and transistors. -A LED. You can use any NPN type transistor (for example 2N3904, BC547, BC548, BC549 etc.) These are basic circuits, so they can be improved (with diodes for reverse voltage protection ...
Webdevices, that are similar to PNP transistors. Although it is common knowledge that HEXFET®transistors are more easily driven than bipolars, a few basic considerations have to be kept in mind in order to avoid a loss in performance or outright device failure. 2. GATE VOLTAGE LIMITATIONS Figure 2 shows the basic HEXFET®structure. WebDec 31, 2024 · Open Collector Outputs Summary. We have seen here in this tutorial about the open collector output that it can provide a current sink or current source output depending on the type of bipolar transistor, NPN-type or PNP-type, used. When an NPN-type transistor is in its “ON” state, it will provide or “sink” a path to ground.
